Control Arms and Bushings
- Remove the wheel using a lug wrench.
- Use a socket set to unbolt the control arm from its mount.
- Inspect the bushings for cracks or excessive wear; replace if necessary.
- Install new control arm bushings and torque to manufacturer specifications.
Shock Absorbers
- Locate the upper and lower mounting bolts of the shock absorber.
- Use a socket set to remove the bolts and detach the shock.
- Compare the old shock to the new one to ensure proper size.
- Install the new shock absorber, tightening bolts to specified torque.
Sway Bar Links
- Inspect sway bar links for wear; replace if they are damaged or loose.
- Remove the sway bar link from the sway bar and lower control arm.
- Install the new sway bar link and tighten to the manufacturer’s specifications.

3. Reassemble and Test

Reinstall the wheel and lug nuts, tightening them in a crisscross pattern to the specified torque.
Lower the vehicle and reconnect the battery if previously disconnected.
Test drive the vehicle to ensure that the noise has been resolved.
