Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Gather safety equipment (gloves, goggles).

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle (depending on where the noise is coming from).
Secure with jack stands for safety.

3. Inspect and Replace Components

A. Inspect Bushings

Remove any necessary covers or shields to access the suspension.
Check all rubber bushings for signs of wear, cracking, or deterioration.
Replace any worn bushings with new ones.
- Tools Required: Wrench set, bushing removal tools.

B. Check Shocks/Struts

Examine shocks or struts for leaks or damage.
If damaged, remove the shock/strut assembly.
- Remove the top and bottom mounting bolts.
- Use a spring compressor to safely remove the spring from the strut assembly.
Replace with new shocks or struts.
- Tools Required: Spring compressor, socket set, torque wrench.
- Torque values: Refer to the vehicle service manual for proper torque specifications.

4. Reassemble and Lower Vehicle

Reinstall any components removed during the inspection.
Ensure all bolts are tightened to the specified torque values.
Carefully lower the vehicle back to the ground.
