Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety goggles and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure the vehicle on jack stands to ensure stability while working.

3. Inspect and Replace Components

A. Check Struts and Shocks

Remove the wheel to access the strut assembly.
Inspect the strut for any oil leakage or physical damage.
If damaged, use a socket set to remove the strut bolts and replace with new struts.

B. Inspect Sway Bar Links

Locate the sway bar links connected to the sway bar and control arm.
Check for any play or damage in the sway bar links.
If defective, remove the nuts using a wrench and replace the sway bar links.

C. Replace Bushings

Identify the bushings on control arms and sway bar.
Remove the control arms if necessary, and use a bushing press to remove old bushings.
Install new bushings and ensure they are properly lubricated.

4. Reassemble and Lower Vehicle

Reattach the wheel and tighten the lug nuts to manufacturer torque specifications.
Lower the vehicle from the jack stands and remove the jack.
