GM 23127629
Knuckle, Driver Side

A technician must use the following steps to repair the Steering Knuckle: first raise the vehicle followed by tire removal. For maintenance you must remove the drive axle nut before putting a drift stick or screwdriver into position between caliper and rotor to stop rotor movement. The service requires removing caliper and support bracket bolts which enables suspension of the caliper while it rests apart from the brake rotor. Start by taking out the rotor then disconnect the wheel speed sensor connector. To remove the hub and drive axle, first remove hub and bearing retaining bolts then extract the components using the hub and bearing puller (J28733-B). You must first separate the Tie Rod from the Steering Knuckle using "steering linkage and Tie Rod puller" (J24319-B) before you proceed to remove dust shield components and all front strut-to-Steering Knuckle retaining bolts. Use the Ball Joint separator (J43828) to disconnect the Ball Joint from the Steering Knuckle before Steering Knuckle extraction. Begin by adding the Steering Knuckle followed by the lower Ball Joint to the installation. Secure the Tie Rod while tightening its end to knuckle nut with 10 nm force (88 inch lbs.) followed by an additional 180 degrees to 300 degrees (3 to 5 flats) while maintaining perfect cotter pin alignment without altering the nut's position. Install the dust shield followed by the hub and bearing to the Steering Knuckle/drive axle and apply 95 nm torque (70 ft. Lbs.) to hub and bearing retaining bolts. After connecting the wheel speed sensor you should install both the rotor and caliper support bracket followed by the caliper assembly. To install the drive axle nut first position a drift or screwdriver between the caliper and rotor to stop rotor motion then apply torque at 145 nm (107 ft. Lbs.) before reattaching the wheel with a final torque of 140 nm (100 ft. Lbs.).

First, raise and support the vehicle to replace the Steering Knuckle. Take off the bearing/hub assembly, then remove two front lower control arm ball stud from the Steering Knuckle, and the outer Tie Rod End. Scribe the strut to the knuckle and remove the bolts and nuts securing the strut to the knuckle before removing the knuckle from the vehicle. For the installation, again place the knuckle on to the vehicle, and then install the through bolts and nuts that join the strut to the knuckle that are tightened to 120 nm (89 ft. Lbs.). Next, attach the outer tie rod to the Steering Knuckle and the front lower control arm ball stud to the knuckle and then set up the front wheel drive shaft bearing. Finally, decrease the vehicle and check the front wheels alignment, if there are any adjustments too.

Before performing repairs or servicing on the Steering Knuckle users must first safely raise and adequately support the vehicle. The first step requires removal of tire and wheel assembly then front wheel drive shaft bearing. First remove the front lower control arm ball stud then use the universal steering linkage puller (J 24319-B) to remove the outer Tie Rod End from the Steering Knuckle. You should first scribe the strut to the knuckle before removing the bolts between strut and knuckle to extract the knuckle from the vehicle. Use the knuckle to reposition itself onto the vehicle before installing the bolts connecting the strut to the knuckle while torquing them to 122 nm (90 ft. Lbs.). Install the outer tie rod onto the Steering Knuckle before fastening the front lower control arm ball stud to the knuckle earlier mounting the front wheel drive shaft bearing. Place the tire and wheel combination back on the vehicle then lower it down.

To change the Steering Knuckle have initially the vehicle to be raised properly and supported. Once the tire and wheel assembly has been removed, next comes the front wheel drive shaft bearing. Subsequently, disconnect the front lower control arm ball stud and take out the outer Tie Rod End from Steering Knuckle. Scribe the strut to the knuckle and then take off the bolts that are connecting the strut to the knuckle before taking off the knuckle from the vehicle. To install, start by installing the knuckle back to the vehicle. Mount the bolts that join to the strut to the knuckle, making sure to tighten them up to 123 nm (90 ft. Lbs.). Remove the adapter washer to fit and replace then remove the top nut, lock washer and nut then washers and nut to the Steering Knuckle not the strut. The ball stud now goes on the front lower control arm knob to the knuckle steer the wheel drive shaft bearing then reattach the outer tie rod to the Steering Knuckle and the front bottom then lower. Lastly, reinstall the tire and wheel assemy and lower the vehicle. There is a list of tools that are needed for this procedure including the j24319-b universal steering linkage puller.

Service and repair operations for the Steering Knuckle start from elevating the vehicle correctly while providing safe support followed by tire and wheel assembly removal. Start by taking off the front wheel drive shaft bearing. Use the j 41820 ball joint/stud separator (J 41820) on the front lower control arm stud to detach it from the front Steering Knuckle while removing the front lower control arm ball stud-to-knuckle cotter pin and nut. Use the j 24319-b universal steering linkage puller (J 24319-B) to detach the outer Tie Rod End from the Steering Knuckle before scribing the strut to the knuckle and removing connecting bolts so you can remove the knuckle from the vehicle. The installation procedure requires fitting the knuckle onto your vehicle followed by bolting the strut to the knuckle and tightening these bolts to 123 nm (90 ft. Lbs.). Connect the outer tie rod to the Steering Knuckle before adding the front lower control arm ball stud to its attachment point on the knuckle. Finally, install the front lower control arm ball stud nut until it reaches 55 nm (40 ft. Lbs.) torque while shifting the slots to match the cotter pin hole without letting the nut loosen. To finish up install the front lower control arm ball stud cotter pin then reattach the front wheel drive shaft bearing before replacing the tire with the wheel assembly followed by vehicle lowering.

To change the Steering Knuckle, the first thing you need to do is lift and support the vehicle in a suitable way. After this, there is a need to take the tire and wheel assembly and the front wheel drive shaft bearing off. Then, remove the front lower control arm ball stud and the outer Tie Rod End from the Steering Knuckle by using the steering linkage and tie rod puller (J 24319-B). Scribe the strut to the knuckle, and then take off the bolts that attach the strut to the knuckle before you pull the knuckle out of the vehicle. For installing, locate the knuckle back on the vehicle and install the bolts that secure the strut to the knuckle, make sure you tighten them to 123 nm (90 ft. Lbs.). Reattach the outer tie rod to the Steering Knuckle and then connect the front lower control arm ball stud to the knuckle and finally replace the front wheel drive shaft tyre bearing. Finally, once you're done, place the tire and wheel assembly back on and lower the vehicle.

The service and repair process of the Steering Knuckle starts when you properly lift and properly support the vehicle first. The first step is to remove the tire and wheel assembly then the front wheel drive shaft bearing. You need to take out the ball stud at the front lower control arm. When the outer Tie Rod End needs detachment from the Steering Knuckle use the universal steering linkage puller (J 24319-B). Rote the strut with a marker onto the knuckle first before uninstalling the bolts between the knuckle and strut for removal. Position the knuckle back onto the vehicle before tightening its bolts connecting the strut to the knuckle at 122 nm (90 ft. Lbs.). First reinstall the outer tie rod onto the Steering Knuckle then join the front lower control arm ball stud to the knuckle before installing the front wheel drive shaft bearing. Put the tire along with its wheel assembly back into place and lower the vehicle.

Repair or service operations on the Steering Knuckle require initial vehicle elevation along with adequate support. Begin repairing the Steering Knuckle by removing first the front wheel drive shaft bearing alongside the tire and wheel assembly. You must detach the ball stud of the front lower control arm next. Use universal steering linkage puller (J24319-B) to detach the outer Tie Rod End from its connection with the Steering Knuckle. First mark the strut's position on the knuckle before uninstalling the bolts that connect the strut to the knuckle and remove the knuckle from the vehicle. Reposition the knuckle back onto the vehicle before you insert the bolts to connect the strut to the knuckle then tighten them to 123 nm (90 ft. Lbs.). Install the front wheel drive shaft bearing by connecting the front lower control arm ball stud to the knuckle followed by reattaching the outer tie rod to the Steering Knuckle. Put the tire-wheel combination onto the vehicle before lowering it down.

Start the Steering Knuckle replacement process by lifting the vehicle before securely supporting it. Start by removing the tire wheel assembly then proceed to detach both the front wheel drive shaft bearing. Break the front lower control arm ball stud loose from its position. The steering linkage and tie rod puller (J 24319-B) serves to disconnect the outer Tie Rod End from the Steering Knuckle assembly. Scribe the strut to the knuckle before removing the bolts connecting the strut to the knuckle allowing removal of the knuckle from the vehicle. Before the knuckle reinstatement place it back onto the vehicle and bolt it to the knuckle using 112 n.m (83 lb ft). After reconnecting the outer tie rod to the Steering Knuckle you can attach the front lower control arm ball stud to the knuckle followed by installing the front wheel drive shaft bearing. Place the tire and wheel assembly back in position then lower the vehicle.
