Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and eye protection.

2. Lift the Vehicle

Use a jack to lift the vehicle at the designated lift points.
Secure the vehicle with jack stands for safety.

3. Inspect and Replace Components

A. Inspect Shock Absorbers

Remove the lower mounting bolts using a socket set (typically 15mm or 18mm).
Pull down the shock absorber to inspect for leaks or physical damage.
If damaged, replace the shock absorber with a new one.

B. Check and Replace Sway Bar Links

Locate the sway bar links and remove the nuts using a wrench.
Inspect for any play or damage; replace if necessary.
Install new sway bar links, ensuring they are tightened to manufacturer specifications (usually around 30 ft-lbs).

4. Reassemble and Lower Vehicle

Reattach the shock absorbers and tighten bolts to manufacturer specifications (usually 40-50 ft-lbs).
Carefully lower the vehicle back to the ground.

5. Final Inspection

Inspect all fasteners to ensure they are tight.
Perform a test drive to verify the repair.
