Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Lift 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 to ensure safety.

3. Inspect and Replace Components

A. Shock Absorbers/Struts

Remove: Disconnect the top and bottom bolts using a socket set and ratchet.
Inspect: Check for oil leaks or excessive wear on the shock body.
Replace: Install new shock absorbers/struts, tightening the bolts to the manufacturer’s specified torque (usually around 40-60 ft-lbs).

B. Control Arms and Bushings

Remove: Unbolt the control arms from the frame and subframe using a socket set.
Inspect: Look for cracks in the control arm and wear on the bushings.
Replace: Install new control arms and bushings, ensuring proper alignment and tightening to specifications.

C. Sway Bar Links and Bushings

Remove: Unbolt the sway bar links from the sway bar and control arms.
Inspect: Check the bushings for deterioration and the link for play.
Replace: Install new sway bar links and bushings, torquing to the manufacturer’s specifications.
