Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Loosen lug nuts and raise the vehicle securely on jack stands.

2. Inspect and Replace Worn Components

A. Shock Absorbers/Struts

Remove the wheels for better access.
Inspect the shocks/struts for leaks or physical damage.
If damaged, use a socket set to remove the mounting bolts and disconnect the shocks/struts.
Install new shocks/struts by reversing the removal process. Torque the mounting bolts to manufacturer specifications (typically around 30-40 lb-ft).

B. Bushings

Check control arm and sway bar bushings for signs of cracking or wear.
If worn, use a bushing removal tool to extract the old bushings.
Lubricate the new bushings with silicone grease and install them, ensuring they are seated properly.

3. Reassemble and Secure

Reattach the wheels and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and then torque the lug nuts to manufacturer specifications (typically around 100 lb-ft).
