Move positioning the seal and then access the lower pinch bolt that is addressing the intermediate Steering Shaft and remove the lower pinch bolt on the power steering gear stub shaft. Danziela the front wheels in a straight and the Steering Column in lock position before disprotecting the latter Steering Column or intermediate shaft so that it does not align incorrectly and the restraints coil assembly could be damaged. Push in the Steering Column lock pin (J42640) into the Steering Column access hole to hold the orientation, and remove the intermediate Steering Shaft from the power steering gear stub shaft, marking the shaft to gear alignment for installation. Lower the vehicle and reposition the seal to gain access to the upper pinch bolt of the intermediate Steering Shaft, then remove the upper pinch bolt and disconnect the intermediate Steering Shaft from the Steering Column, taking note of the shaft to column alignment, for reinstallation. Eliminate the internal Steering Shaft from the car. Install involving a placement of the intermediate Steering Shaft into the seal and connection with the Steering Column as recorded in the extraction process. Install the upper intermediate Steering Shaft pinch bolt and tighten it to 48 nm (35 ft. Lbs). Attach the intermediate Steering Shaft seal onto the Steering Column, lift the vehicle, and attach the intermediate Steering Shaft to the power steering gear stub shaft as documented during removal. Lastly, install pinch bolt lower intermediate steering strap and tighten to 48n m (35Ft.Lb), attach the intermediate steering strap seal onto the power steering gear and rotate the lower seal as required by having maximum clearance and lower the vehicle.

To replace the intermediate Steering Shaft, take off the Steering Column then lift up and jack the vehicle. Then, you will need to take off the left front tire as well as the pinch bolt at the power steering gear stub shaft, followed by the removal of the intermediate shaft from the power steering gear stub shaft and the intermediate Steering Shaft itself. In the installation process, start by installing the intermediate shaft to the power steering gear stub shaft and ensure that you are following the fastener notice in service precautions. After that, mount the pinch bolt to the power steering gear stub shafts, as well as tightening it to 47 nm (35 ft. Lbs). After that, install the left front tire again, lower the vehicle, and finally install the Steering Column.

The first step before replacing the intermediate Steering Shaft involves lifting and supporting your vehicle. Use the positioner to access the lower part of the intermediate Steering Shaft's pinch bolt before removing the lower bolt on the power steering gear stub shaft. Before removing any components start by positioning the Steering Column at lock and ensuring the front wheels face forward. This step prevents alignment issues that would harm the sir coil assembly. After the j 42640 Steering Column lock pin (J 42640) fits into the Steering Column access hole users can preserve the Steering Column's orientation. First disconnect the intermediate Steering Shaft from the power steering gear stub shaft while carefully recording its alignment setup. Then lower the vehicle to the ground. First reposition the seal to reach the upper pinch bolt on the intermediate Steering Shaft then remove this pinch bolt and finally separate the intermediate Steering Shaft from the Steering Column while keeping track of the required alignment for future reassembly. The intermediate Steering Shaft requires removal from its position in the vehicle. After securing the intermediate Steering Shaft inside the seal, reinstall it to the Steering Column while maintaining the original connection points as established during disassembly. Fasten the upper intermediate Steering Shaft pinch bolt to a torque specification of 48 nm (35 ft. Lbs.). After connecting the intermediate Steering Shaft seal to the Steering Column the technician will raise the vehicle to complete the power steering gear stub shaft installation using markings made during removal. After securing the lower intermediate Steering Shaft pinch bolt at 48 nm (35 ft. Lbs.) install the intermediate Steering Shaft seal onto the power steering gear. Then rotate the lower seal to achieve maximum clearance before lowering the vehicle.

To replace the intermediate Steering Shaft; remove the Steering Column which has the intermediate shaft attached. Next, disconnect the intermediate shaft pinch bolt at the Steering Column and then remove the intermediate Steering Shaft. To install, connect the intermediate Steering Shaft to the Steering Column while adhering to the fastener notice in service precautions. Then install the pinch bolt to the power steering gear stub shaft and tighten it to 47 nm (35 ft.lbs.). Finally, reassemble the Steering Column with the intermediate shaft.

Vehicle maintenance begins by removing the Steering Column followed by vehicle elevation with proper support for replacement of the intermediate Steering Shaft. Start by taking off the left front tire and pinch bolt at the power steering gear stub shaft before removing both the intermediate shaft from power steering gear stub shaft and the intermediate Steering Shaft. Start installation by placing the intermediate shaft onto the power steering gear stub shaft while following the fastener notice in service precautions. Secure the pinch bolt to the power steering gear stub shaft through proper torque termination at 47 nm (35 ft. Lbs.). Reinstall the left front tire followed by lowering the vehicle to complete the installation with the Steering Column.

The first step for upper intermediate Steering Shaft replacement requires front wheels to be in a straight position when Steering Column is locked to protect the sir coil assembly from damage and misalignment. Disable the sir system. The Steering Column needs to be removed as a single unit with the upper intermediate shaft in place. Move forward with rotating the Steering Column away immediately. Carefully observe how the upper intermediate shaft connects with the Steering Column since this information will help with installation. After removing the upper intermediate Steering Shaft to Steering Column bolt detach the upper intermediate Steering Shaft from the Steering Column. First secure the upper intermediate Steering Shaft on the Steering Column according to the removal steps then tighten the Steering Column bolt to 48 nm (35 ft. Lbs.). Reinstall the Steering Column then enable the sir system after you attach the upper intermediate Steering Shaft.

To replace upper intermediate Steering Shaft, first deactivate the sir system. Make sure that the front wheels are straight and the Steering Column is in the lock position prior to the disconnections of the Steering Column or intermediate shaft in order to avoid incorrect alignments and sir coil assembly damage. If you take the Steering Column remove it with the upper intermediate shaft still connected, after noting the relationship between the two in order to properly place it. Then, get rid of the upper intermediate Steering Shaft to Steering Column bolt and pull off the upper intermediate Steering Shaft from the Steering Column. To install, attach upper intermediate Steering Shaft to Steering Column as referred to above during removal, and install the upper intermediate Steering Shaft to Steering Column bolt which should be tight at 48 n.m (35 lb ft). Lastly, install the Steering Column and also activate the sir system.

The intermediate Steering Shaft replacement process starts by removing the Steering Column followed by raising and supporting the vehicle. The first step of replacement involves tire removal and pinch bolt removal from the power steering gear stub shaft and subsequent steps include removing the intermediate shaft along with the intermediate Steering Shaft itself. When performing installation begin by attaching the intermediate shaft to the power steering gear stub shaft while following the fastener notice in service precautions. Install the pinch bolt to the power steering gear stub shaft before tightening it to 47 nm using a beam torque wrench (35 ft. Lbs.). Reinstall the left front tire followed by vehicle positioning and completion of Steering Column installation.

Start by turning the steering wheel left to access the upper to lower intermediate shaft bolts before locking the ignition position. Start by removing the upper to lower intermediate shaft bolts followed by the Steering Column and upper intermediate Steering Shaft from inside the vehicle compartment. Put the upper intermediate Steering Shaft into the intermediate shaft seal while inside the vehicle before installing the Steering Column. Install the lower intermediate shaft onto the upper intermediate shaft following the instructions from the fastener notice in service precautions and then torque the retaining bolts to 48 nm (35 ft. Lbs.).

Before you can replace the upper intermediate Steering Shaft, disable the sir system. Make sure the front wheels are straight and the Steering Column is in lock position before disconnecting the Steering Column or intermediate shaft so as not to have improper alignment as well as damage to the sir coil assembly. Remove the Steering Column along with the upper intermediate shaft from it and remember the fixed placing of the two of them to install properly. Then, remove the upper intermediate shaft to Steering Column retaining bolt and disconnect the upper intermediate shaft from the Steering Column. For installation attach the upper intermediate shaft to the Steering Column as indicated during removal, then bolt it using the retaining bolt, tighten bore to the point of 48 n.m (35 lb ft). Finally, install the Steering Column and enable the sir system.

Begin the lower intermediate Steering Shaft replacement process by first ensuring the vehicle's front wheels face straight ahead and that the Steering Column remains in lock position to avoid damaging the sir coil assembly. Use Steering Column anti-rotation pin (J42640) to lock the Steering Column. Raise and support the vehicle. Record the fit between the center intermediate shaft and lower intermediate shaft that will guide the installation process. Move the retaining bolt connecting the center intermediate shaft to the lower intermediate shaft before removing the retaining bolt which connects the lower intermediate shaft to the power steering gear. First cut the lower intermediate shaft loose from the power steering gear before removing it from the center intermediate shaft. Install the lower intermediate shaft by first connecting it to the center intermediate shaft and afterwards to the power steering gear. Secure both components with torque wrenches: bolt 1 to 50 nm (37 ft. Lbs.) and bolt 2 to 30 nm (23 ft. Lbs.). Lower the vehicle before removing the Steering Column anti-rotation pin (J42640) through the lower Steering Column trim cover access hole.

The first step to replace the lower intermediate Steering Shaft requires straight-wheeled positioning and lock-positioned Steering Column because the sir coil assembly risks damage. Fit the Steering Column anti-rotation pin (J 42640) inside the Steering Column lower access hole. Note the position of the lower intermediate shaft to the power steering gear before removing its retaining bolt to the power steering gear. Access the power steering gear by removing the lower intermediate shaft and its retaining bolt for the intermediate shaft bearing. Take off the lower intermediate shaft from the intermediate shaft bearing before removing it from the vehicle. Follow these installation steps by inserting the lower intermediate shaft into the vehicle before you attach it to the intermediate shaft bearing. Place the intermediate shaft bearing retaining bolt then torque it to 30 nm (22 ft. Lbs.). Place the earlier-made marks correctly and fasten the lower intermediate shaft to the power steering gear using a bolt that needs tightening to 61 nm (45 ft. Lbs.). Remove the Steering Column anti-rotation pin (J 42640) from the Steering Column lower access hole as your final step.

As a first step to service or repair the steering shaft with its bearing and jacket users need to disable the SIR system. Disassemble the system by removing the wiper/washer switch bracket, tilt spring, steering shaft seal, sensor retainer, sensor assembly, and adapter and bearing assembly. Attach the J 21854-01 Pivot Pin Remover to separate the 2 pivot pins found in the steering column support assembly. Pull the tilt lever to disengage the steering column lock shoes from their position on the dowel pins in the steering column tilt head housing assembly. Disassemble the jacket assembly by taking the steering column tilt head housing assembly and steering shaft assembly together before removing the steering shaft from the tilt head housing assembly. Sliding markers on the race and upper shaft assembly and the lower steering shaft assembly prevents wrong assembly which would lead to a 180-degree steering wheel misalignment. Tilt the race and upper shaft assembly to a 90-degree position so its disengagement from the lower steering shaft assembly becomes possible before screw removal of the 4 TORX head screws. The steering column support assembly needs to be reinstalled onto the steering column jacket assembly while securing the installation with 4 TORX head screws tight to 17 Nm (13 ft. lbs.). The exposed shaft engagement areas on the centering sphere need GM P/N 12345718 (Canadian P/N 10953516) application before the lower steering shaft assembly can be installed to meet the race and upper shaft assembly. Feed the steering shaft assembly into the steering column tilt head housing assembly . Next install both the steering column tilt head housing assembly and the steering shaft assembly to the steering column jacket assembly. Put the 2 pivot pins back into the steering column support assembly but replace it if you've staked it more than 3 times. Then stake the pivot pin positions properly. The final step will be installing the adapter and bearing assembly followed by the sensor assembly and sensor retainer and steering shaft seal and wiper/washer switch bracket and tilt spring after enabling the SIR system.

Lift and prop the vehicle to replace the intermediate Steering Shaft. Disassembly of the tire and wheel assembly while you keep the front wheels in the straight position and the Steering Column in lock position to ensure they do not look misaligned. Insert the Steering Column anti-rotation pin (J 42640) to the bottom of the Steering Column and access the lower pinch bolt from the power steering gear stub shaft to be removed. Remove the intermediate Steering Shaft from the power steering gear stub shaft and lower the vehicle. Then take off the left closeout panel and reposition the intermediate Steering Shaft seal to allow upper pinch bolt be accessed. Take off the upper pinch bolt, and disengage the intermediate Steering Shaft from the Steering Column before detaching it totally. During installation, locate the new intermediate Steering Shaft and clamp this to the Steering Column with the top pinch bolt then tighten to 62 n.m (46 lb ft). Put the intermediate Steering Shaft seal onto the Steering Column then once more raise and supporting the vehicle again. Join the intermediate Steering Shaft to the power steering gear stub shaft to fix it with the lower pinch bolt turned to 48 n.m (35 lb ft). Steering Column anti-rotation pin (J 42640) must be removed, the intermediate Steering Shaft seal must be installed to the power steering gear, the tire and wheel assembly must then be reinstalled while lowering the vehicle, and then lastly, the left closeout panel must also be installed.

Before replacing the intermediate Steering Shaft, raise and support the entire vehicle in an upright position. Your first step should be to remove the wheel and tire assembly while keeping both front wheels aligned straight and spinning the Steering Column to lock to protect against sir coil assembly issues. Position the Steering Column anti-rotation pin (J 42640) into the bottom segment of the Steering Column. First position the intermediate Steering Shaft seal to see the lower pinch bolt. Then take off this bolt from the power steering gear stub shaft and separate the intermediate Steering Shaft from both components. Lower the car while you remove the left instrument panel insulator from its place. First reposition the intermediate Steering Shaft seal to reach the upper pinch bolt. Next remove this bolt while disconnecting the intermediate Steering Shaft from the Steering Column. Place the intermediate Steering Shaft into position and insert the upper pinch bolt to the Steering Column. Properly torque the bolt to 48 nm (35 ft. Lbs.). Lift your vehicle once more for support while you attach the intermediate Steering Shaft to the power steering gear stub shaft. Fitting the lower pinch bolt requires a torque of 48 nm (35 ft. Lbs.) before removing the Steering Column anti-rotation pin (J 42640). After lowering the vehicle place the left instrument panel insulator and finish by installing both the tire and wheel assembly and the power steering gear intermediate Steering Shaft seal.

The process of installing a new intermediate Steering Shaft begins by first identifying two essential requirements.alignment of the front wheels and a lock position of the Steering Column prevent both structural misalignment and any harm to the sir coil assembly. Elevate your vehicle before reaching the adjacent Steering Shaft crank. Shift the intermediate Steering Shaft seal for exposure to the lower attaching bolt. Use a wrench to detach the lower pinch bolt from power steering gear stub shaft and freely separate the intermediate Steering Shaft. You must lower the vehicle next to remove the left knee bolster. Then use the intermediate Steering Shaft seal to reach the upper pinch bolt. Asthe final step disconnect the intermediate Steering Shaft from the Steering Column after you remove its upper pinch bolt. Before installation follow the fastener notice precautions then align the intermediate Steering Shaft correctly before fastening the upper pinch bolt at the Steering Column using 48 nm torque. Start by positioning the intermediate Steering Shaft seal on the Steering Column then raise the vehicle again along with supporting it while you connect the intermediate Steering Shaft to the power steering gear stub shaft. Begin by attaching the lower pinch bolt at the power steering gear stub shaft while tightening it to 48 nm (35 ft. Lbs.). Next, position the intermediate Steering Shaft seal onto the power steering gear. Lower the vehicle before reinstalling the left knee bolster.

Start the upper intermediate Steering Shaft replacement by setting the vehicle's wheels in a straight position and locking the Steering Column because this prevents sir coil assembly damage. Start your procedure by inserting the Steering Column anti-rotation pin (J42640) through the Steering Column's lower access hole. Begin by taking off the intermediate shaft bearing and then the retaining nut and bolt which fasten the upper intermediate shaft to the Steering Column. Disconnect the upper intermediate shaft from the Steering Column and take it away. Start assembly by joining the upper intermediate shaft to the Steering Column and finally secure it with the retaining nut and bolt. Tighten the nut to a torque of 64 nm (47 ft. Lbs.). Reinstall the intermediate shaft bearing then remove the Steering Column anti-rotation pin (J42640) through the column lower access hole.

While replacing the upper intermediate Steering Shaft, the vehicle wheels have to be straight ahead and the Steering Column has to be lock to avoid the damage of sir coil assembly. Start by installing the Steering Column anti-rotation pin (J 42640) in the lower access hole of the Steering Column. Then take off the intermediate shaft bearing, then the retaining nut and bolt for the upper intermediate shaft to the Steering Column. Remove the upper intermediate shaft from the Steering Column, then disconnect it. For installation, attached the upper intermediate shaft to the Steering Column, attach the retaining nut and bolt (2 to 1) and tighten the nut hence to 64 nm (47 ft. Lbs.). Lastly, install the intermediate shaft bearing; take off Steering Column anti-rotation pin (J 42640) from the Steering Column low access hole.

You need to start by locking the Steering Column and positioning all wheels straight ahead to stop damage from happening to sir coil assembly before you can replace the lower intermediate Steering Shaft. Drivers should start by placing the Steering Column anti-rotation pin (J 42640) into the lower access hole on the Steering Column. Take a marker to record the lower intermediate shaft's position as it relates to the power steering gear because you will need this information for reassembly. Use a socket to remove the retaining bolt which maintains the lower intermediate shaft connection to the power steering gear subsequently disconnect the shaft from the gear. To proceed with the disassembly start by taking out the bolt which holds the lower intermediate shaft to the intermediate shaft bearing and then separate the shaft from the bearing component.
