How to replace the lower control arm on those equipped with an aluminum lower control arm on GMC Yukon?

The repair process for aluminum lower control arms starts with vehicle suspension and subsequent wheel removal before stabilizer shaft link detachment from the Control Arm and wheel drive shaft removal when necessary. First detach the stabilizer shaft link from the lower Control Arm and disconnect the wheel drive shaft if your vehicle has this part installed. Use mechanics wire or equivalent to support the knuckle assembly with the upper Control Arm. First remove the lower shock module bolt screws from the lower Control Arm then discard the lower Ball Joint retaining nut. The j 43631 (Ball Joint Separator) combined with j 45851 (Ball Joint Separator Protector Adapters) enables technicians to detach the lower Ball Joint from the Steering Knuckle. Take the Control Arm nuts and washers away followed by the Control Arm bolts to extract the Control Arm. Position the lower Control Arm accurately and fasten it with Control Arm bolts coupled with washers for installation. Screw and tighten the lower Control Arm retaining nuts to 175 nm (129 lb ft). If the Steering Knuckle features a captured washer use 125 nm (92 lb ft) torque and 50 nm plus 130 degrees (37 lb ft) if it does not have a captured washer to fasten the lower Ball Joint into position. Fasten the lower shock absorber module mount bolts with torque setting at 50 nm (37 lb ft). Reinstall the wheel drive shaft only if required before removing support for both the Steering Knuckle and upper Control Arm. Reinstall the tire with the wheel before removing support then lowering the vehicle for front end alignment.

How to replace the lower control arm (1500) on GMC Sierra 1500?

Begin by elevating and supporting your vehicle before removing the tire along with wheel to replace the lower Control Arm (1500). Complete the following tasks: first, disconnect the stabilizer shaft link from the lower Control Arm and then remove the wheel drive shaft if your vehicle has it. Use mechanics wire or equivalent to support the knuckle assembly and upper Control Arm. First remove the lower Ball Joint retaining nut before using tools to disassemble the lower shock module bolts from the lower Control Arm. The j 43631 and j 45851 tools should be used to remove the lower Ball Joint connection between the Steering Knuckle. The nuts securing the lower Control Arm need removal before removing Control Arm hardware consisting of washers and Control Arm bolts. Position the lower Control Arm in the correct location and use Control Arm bolts a well as washers to secure it. Wedge the lower Control Arm retaining nuts right after installation before tightening them to 175 nm (129 lb ft). Lock down the lower Ball Joint inside the Steering Knuckle through the installation of a fresh retaining nut which you should tighten to 125 nm (92 lb ft). Follow the procedure to attach the lower shock absorber module mount bolts before applying 50 nm (37 lb ft) torque. First remove the upper Control Arm's support and Steering Knuckle support before reinstalling the wheel drive shaft when needed. Replace the stabilizer shaft link onto the lower Control Arm and add the tire along with wheel then pull off the support and lower the vehicle. Finally, align the front end.

GMC Control Arm

Choose OEM Control Arm, you're making the optimal decision for superior quality and perfect performance. You can feel confident because each component goes through stringent quality checks. Every part is carefully built to comply with GMC's factory specifications. You'll enjoy a smooth, worry-free installation that fits just right.

All our genuine GMC parts include a dependable manufacturer's warranty. You'll also appreciate our straightforward return policy and swift delivery services for extra convenience.

GMC Control Arm maintains the position of wheels under the load, thus rides remain stable and predictable. The company was founded in 1901 through hauling roots, constructs trucks and SUVs that shun off heavy loads. GMC joins rigid frames in such a manner that they do not twist and descends in torque-rich powertrains without drama-towing. Its MultiPro tailgate folds, unfolds and turns into a single-person task to be able to load lumber or vehicles. Silent cabins dampen the road noise and such safety features as surround view display the blind spots before misfortune strikes. GMC also does stress tests on the punishing tracks, pursuing the reliability figures that retain the levels. Continuous technological advancements come with time but initial attention is on brute capability. Motorists choose the rig, aim it at employment or mountain, and hope it will come back intact. Control Arm connecting the frame and the wheel hub with bushings and a ball joint allows the suspension to swing up and down without altering tire angle despite being hammered by potholes or trail ruts and cuts weight by modern cast aluminum versions without sacrificing strength, as they combat rust and shave unsprung mass to make the car more responsive. The wear indicated in Control Arm wear is clunking or wandering, thus performance versions employ heavier joints or reinforced steel to deliver lifted suspension, sporty motoring, and mixed terrain operation without losing ride quality.

GMC Control Arm Parts and Q&A

Lower Control Arm, Driver Side
20869201
Q: How to replace the lower control arm on those equipped with an aluminum lower control arm on GMC Yukon?
A:
The repair process for aluminum lower control arms starts with vehicle suspension and subsequent wheel removal before stabilizer shaft link detachment from the Control Arm and wheel drive shaft removal when necessary. First detach the stabilizer shaft link from the lower Control Arm and disconnect the wheel drive shaft if your vehicle has this part installed. Use mechanics wire or equivalent to support the knuckle assembly with the upper Control Arm. First remove the lower shock module bolt screws from the lower Control Arm then discard the lower Ball Joint retaining nut. The j 43631 (Ball Joint Separator) combined with j 45851 (Ball Joint Separator Protector Adapters) enables technicians to detach the lower Ball Joint from the Steering Knuckle. Take the Control Arm nuts and washers away followed by the Control Arm bolts to extract the Control Arm. Position the lower Control Arm accurately and fasten it with Control Arm bolts coupled with washers for installation. Screw and tighten the lower Control Arm retaining nuts to 175 nm (129 lb ft). If the Steering Knuckle features a captured washer use 125 nm (92 lb ft) torque and 50 nm plus 130 degrees (37 lb ft) if it does not have a captured washer to fasten the lower Ball Joint into position. Fasten the lower shock absorber module mount bolts with torque setting at 50 nm (37 lb ft). Reinstall the wheel drive shaft only if required before removing support for both the Steering Knuckle and upper Control Arm. Reinstall the tire with the wheel before removing support then lowering the vehicle for front end alignment.

Q: How to replace the lower control arm (1500) on GMC Sierra 1500?
A:
Begin by elevating and supporting your vehicle before removing the tire along with wheel to replace the lower Control Arm (1500). Complete the following tasks: first, disconnect the stabilizer shaft link from the lower Control Arm and then remove the wheel drive shaft if your vehicle has it. Use mechanics wire or equivalent to support the knuckle assembly and upper Control Arm. First remove the lower Ball Joint retaining nut before using tools to disassemble the lower shock module bolts from the lower Control Arm. The j 43631 and j 45851 tools should be used to remove the lower Ball Joint connection between the Steering Knuckle. The nuts securing the lower Control Arm need removal before removing Control Arm hardware consisting of washers and Control Arm bolts. Position the lower Control Arm in the correct location and use Control Arm bolts a well as washers to secure it. Wedge the lower Control Arm retaining nuts right after installation before tightening them to 175 nm (129 lb ft). Lock down the lower Ball Joint inside the Steering Knuckle through the installation of a fresh retaining nut which you should tighten to 125 nm (92 lb ft). Follow the procedure to attach the lower shock absorber module mount bolts before applying 50 nm (37 lb ft) torque. First remove the upper Control Arm's support and Steering Knuckle support before reinstalling the wheel drive shaft when needed. Replace the stabilizer shaft link onto the lower Control Arm and add the tire along with wheel then pull off the support and lower the vehicle. Finally, align the front end.
