Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use a jack and jack stands to safely lift the rear of the vehicle.

2. Inspect and Replace Components

a. Inspect Suspension Bushings

Remove the rear wheel using a socket set and jack stand.
Check the condition of the bushings on control arms and sway bar links.
If any bushings are cracked or excessively worn, proceed to replace them.

b. Replace Shock Absorbers

Remove the upper and lower bolts of the rear shock absorber using a socket set.
Carefully pull the shock absorber out of the mount.
Install the new shock absorber and torque the bolts to manufacturer specifications (usually around 50-60 ft-lbs).

c. Replace Rear Springs (if needed)

Remove the lower control arm bolts to allow access to the springs.
Use a spring compressor to safely remove the springs from their mounts.
Install new springs, ensuring they are seated properly in their mounts.

3. Reassemble and Test

Reattach all components, ensuring all bolts are torqued to the proper specifications.
Reinstall the rear wheel and lower the vehicle.
Conduct a test drive to check for noise and ensure proper operation.
