Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is off.
Engage the parking brake for safety.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is originating.
Secure the vehicle with jack stands for support.

3. Inspect and Replace Components

A. Shock Absorbers/Struts

Tools Required: Socket set, torque wrench, spring compressor (if replacing struts).
Remove the wheel to access the strut assembly.
Unbolt the strut from the lower control arm and the top mount.
Use a spring compressor to safely remove the spring from the strut if replacing.
Replace with new or refurbished struts, ensuring proper alignment with the mounting points.
Torque bolts to vehicle specifications (refer to service manual for exact values).

B. Sway Bar Links and Bushings

Inspect sway bar links for wear; replace if damaged.
Remove the old sway bar link by unbolting it from both ends.
Install new sway bar links, ensuring proper orientation and torque.

4. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Torque the lug nuts to manufacturer specifications.
