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 originates.
Secure the vehicle with jack stands and ensure stability.

3. Inspect and Replace Bushings

Inspect: Check control arm bushings and sway bar bushings for cracks or excessive wear.
Replace:
- Remove the bolts securing the affected bushings.
- Use a suitable bushing puller to extract the old bushing.
- Install new bushings, applying lubricant as necessary per manufacturer specifications.
- Torque the bolts to the manufacturer’s specifications.

4. Check and Replace Shock Absorbers/Struts

Remove: Detach the top and bottom bolts of the shock absorber/strut assembly.
Inspect: Look for signs of leaking fluid or physical damage.
Replace: Install the new shock absorber/strut assembly, ensuring proper orientation.
Torque all bolts to manufacturer specifications.

5. Examine and Replace Springs (if necessary)

Inspect: Look for sagging or broken coils in the springs.
Remove: If replacement is necessary, compress the spring using a spring compressor and carefully detach it.
Replace: Install the new spring and decompress it slowly.
Recheck all components for proper installation.
