Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Use a jack to raise the rear of the vehicle and support it with jack stands.

2. Remove Wheel

Sub-steps:
1. Use a lug wrench to loosen and remove the lug nuts.
2. Remove the rear wheel to access the suspension components.

3. Inspect Shock Absorbers

Sub-steps:
1. Check for any signs of leaking fluid on the shock absorbers.
2. Push down on the shock absorber to test for resistance. If it compresses easily and does not rebound, it may need replacement.

4. Replace Worn Components

Sub-steps:
1. If the shocks are worn, remove the top and bottom bolts securing the shock to the vehicle using a socket set.
2. Install the new shock absorber in reverse order of removal, tightening the bolts to the manufacturer’s specified torque values (typically around 30-40 Nm for upper bolts).
3. If bushings or links are worn, replace them by removing the corresponding bolts and pressing out the old bushings.

5. Reassemble and Test

Sub-steps:
1. Reinstall the rear wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 100 Nm).
3. Test drive the vehicle to verify that the noise has been resolved.
