Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Safety warning: Disconnect the battery to prevent electrical issues during repair.

2. Inspect and Replace Shock Absorbers (if needed)

Lift the vehicle using a jack and secure it with jack stands.
Remove the rear wheels to gain access to the suspension.
Unbolt the top mount of the shock absorber using a socket set.
Remove the lower mounting bolt from the shock absorber.
Carefully remove the shock absorber from the vehicle.
Compare the old shock absorber with the new one to ensure proper fit.
Install the new shock absorber by reversing the removal steps, ensuring all bolts are torqued to manufacturer specifications (typically around 40-50 ft-lbs).
Reinstall rear wheels and lower the vehicle back to the ground.

3. Inspect and Replace Sway Bar Links (if needed)

With the vehicle elevated, locate the sway bar links on both sides of the vehicle.
Remove the nuts securing the sway bar link to the sway bar and control arm using a wrench.
Inspect the link for wear or damage and replace if necessary.
Install the new sway bar link, ensuring all nuts are tightened to the specified torque (usually around 25-30 ft-lbs).

4. Replace Strut Mounts (if necessary)

Remove the strut assembly from the vehicle, following the proper procedure to detach the top and bottom mounts.
Inspect the strut mounts for cracks or deterioration; replace if necessary.
Reassemble the strut with new mounts and reinstall it on the vehicle.
