Steering Shaft

Before installing the new lower intermediate Steering Shaft maintain front wheel straightness alongside Steering Column lock position because these measures will help prevent sir coil assembly damage through misalignment. Using your hands turn the Ignition Switch to lock then remove the key from the starter. You can lock the Steering Column by using the Steering Column lock pin (J42640) through the opening of the lower trim cover surrounding the Steering Column. Access the upper to lower intermediate pinch bolt by disconnecting the upper intermediate shaft boot from the lower intermediate shaft boot. After this step remove the lower intermediate shaft to upper intermediate shaft pinch bolt. Tear the lower intermediate shaft from the upper intermediate shaft while also detaching the lower intermediate shaft boot from the power steering gear so the intermediate shaft boot can leave the vehicle. During installation, lift the vehicle to observe how the intermediate shaft relates to the power steering gear and Steering Column. Record these measurements for accurate assembly. Unbolt the lower intermediate shaft to the power steering gear input shaft and separate the lower intermediate shaft from the power steering gear. Lower the intermediate shaft into the vehicle until it reaches the power steering gear then secure it with a wrench using 40 nm torque (29 ft. Lbs.). Put the vehicle in its lowered position before installing and connecting the lower intermediate shaft boot to the power steering gear. Tighten the lower intermediate shaft to the upper intermediate shaft through a pinch bolt torque setting of 50 nm (37 ft. Lbs.). Anchor the upper intermediate shaft boot to the lower intermediate shaft boot while making sure both components create a secure seal through the complete coverage of the lower intermediate shaft boot white insert. To unlock the Steering Column remove the Steering Column lock pin (J42640) from the Steering Column lower trim cover access hole.

Disabling the sir system first would be necessary to replace the Steering Shaft. Next, remove the Steering Column tilt head, and then pull out the Steering Shaft from the Steering Column tilt head assembly. Investigate the car's Steering Column for damage due to accidents. During installation, the Steering Shaft must be reinserted back in the Steering Column tilt head assembly and the Steering Column tilt head reinstalled. Finally, enable the sir system.

To replace the steering column shaft, the SIR system needs to be disabled. Next, take out the tilt head of the steering column then remove the steering shaft from the steering column tilt head assembly. Check the steering column for any traces of accidents. Installation involves the replacement of steering shaft back into the steering column tilt head assembly and fitting of steering column tilt head. Finally, enable the SIR system.

In order to change the lower intermediate Steering Shaft, first make sure of the following procedures: the front wheels are straight ahead and the ignition switch is in the lock position without the key in it. Lock the Steering Column from the hole in the bottom trim steering panel using the j 42640 (J 42640). Lift and support the vehicle, then disconnect the pinch bolt lower intermediate shaft to upper intermediate shaft, and disconnect the plastic insert. Remove the upper intermediate shaft from the lower intermediate shaft, and then take the lower intermediate shaft to the power steering gear input shaft pinch bolt and disconnect the lower intermediate shaft from the power steering gear. Slack off the belts and move the lower intermediate shaft. For installation, remove the car's lower intermediate shaft and reinstall it in place attaching it to the power steering gear. Mount the lower intermediate shaft on to the power steering gear input shaft pinch bolt while tightening it to 45 nm (33 ft. Lbs.). Connect the lower intermediate shaft to the upper intermediate shaft such that the plastic insert flat would be aligned with the flat at the lower intermediate shaft during the pinch bolt installation at the upper intermediate shaft. Finally, install the lower intermediate shaft to the upper intermediate shaft pinch bolt and plastic insert, tightening it onto 23 nm (17 ft. Lbs.), drop the vehicle, and unlock the Steering Column by removing the j 42640 (J 42640) from the access hole.

Install the air outlet duct and unlock the steering column by removing the Steering Column Lock Pin (J 42640) from the access hole.

Reconnect the upper intermediate shaft boot to the lower intermediate shaft boot, install the air outlet duct, and unlock the steering column by removing the Steering Column Lock Pin (J42640).

Take out the upper intermediate shaft from the column.

Remove the upper intermediate shaft to steering column pinch bolt and disconnect the upper intermediate shaft from the steering column.

Remove the lower intermediate shaft to the power steering gear input shaft pinch bolt and disconnect the lower intermediate shaft from the power steering gear.

Disconnect the upper intermediate shaft boot from the lower intermediate shaft boot.
