Solution

1. Preparation

Gather tools: jack, jack stands, socket set, torque wrench, pry bar, and a flashlight.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle as necessary.
Secure the vehicle with jack stands to prevent any accidental lowering.

3. Inspect and Replace Components

A. Strut and Shock Absorber Inspection

Remove the wheel to access the strut assembly.
Check for any signs of oil leakage on the struts.
If leaking or damaged, remove the strut assembly:
1. Detach the lower bolt that connects the strut to the lower control arm.
2. Remove the upper strut mounting bolts under the hood.
3. Replace with new struts as per manufacturer specifications (torque to specified values).

B. Sway Bar Link Replacement

Locate the sway bar links connected to the sway bar and control arms.
If damaged, remove the nuts using the socket set.
Replace with new sway bar links and torque to manufacturer specifications.

C. Bushing Replacement

Inspect control arm bushings and sway bar bushings for wear.
If worn, remove the control arm or sway bar to access the bushings.
Press out the old bushings and press in new ones using a bushing tool.

4. Reassemble and Lower Vehicle

Reattach the wheels and lower the vehicle back to the ground.
Torque all wheel lug nuts to manufacturer specifications.
