Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the vehicle to cool down if previously driven.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle depending on where the noise originates.
Secure the vehicle with jack stands for safety.

3. Inspect and Replace Components

A. Shock Absorbers/Struts

Tools Required: Socket set, wrench, spring compressor (if necessary)
Remove the wheel to access the suspension.
Unbolt the top and bottom mounts of the shock absorber/strut assembly.
If the shock is leaking or damaged, replace it with a new unit.
Reinstall the new shock absorber/strut and torque bolts to manufacturer specifications.

B. Bushings and Mounts

Inspect all bushings and mounts for wear.
If any bushings are cracked or degraded, use a bushing removal tool to replace them.
Apply appropriate lubricant to new bushings to facilitate installation and reduce noise.

C. Sway Bar Links and Control Arms

Check sway bar links for play; replace if necessary using a wrench to loosen and remove.
Inspect control arms for damage or excessive wear, replace if needed.
