Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a level surface and ensure the engine is off.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle.
Secure with jack stands to ensure safety while working underneath.

3. Inspect and Replace Components

A. Check Shock Absorbers/Struts

Remove the wheels to access the shock absorbers.
Inspect for any fluid leakage or damaged seals.
If damaged, unbolt the shocks using a socket set and replace with new units.

B. Inspect Control Arms and Ball Joints

Check for excessive play by grabbing the control arm and shaking it.
If worn, remove the nuts and bolts securing the control arm and ball joint.
Replace with new components as necessary.

C. Inspect Sway Bar Links

Locate the sway bar links and check for wear or damage.
Remove the nuts securing the links using a wrench.
Replace with new sway bar links if defective.

4. Reassemble and Lower Vehicle

Reinstall wheels and torque lug nuts to manufacturer specifications (typically 80-100 ft-lbs).
Lower the vehicle carefully and remove jack stands.
