Solution

1. Preparation

Tools Required: Socket set, jack stands, torque wrench, pry bar, and a hammer.
Safety Warnings: Ensure the vehicle is on a flat surface and use jack stands to support the vehicle securely before working underneath.

2. Remove the Rear Wheel

Loosen the lug nuts on the rear wheel using a socket set.
Lift the rear of the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the rear wheel.

3. Inspect and Replace Components

A. Shocks/Struts

Check for any fluid leaks from the shocks/struts.
If damaged, remove the bolts securing the shocks/struts using a socket set.
Install new shocks/struts by reversing the removal process, tightening bolts to manufacturer specifications (usually around 30-40 Nm).

B. Bushings

Inspect all bushings for cracks or deterioration.
Remove the old bushings using a pry bar and hammer if necessary.
Press in new bushings using a suitable tool or socket, ensuring they fit snugly.

C. Sway Bar

Check the sway bar links and bushings for wear.
Remove the sway bar links if damaged, using a socket set.
Replace with new sway bar links and tighten to specifications (usually around 25-30 Nm).

4. Reassemble and Reinstall

Replace the rear wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and then torque the lug nuts to the correct specification (typically 100-120 Nm).

5. Final Inspection

Perform a final inspection of all components to ensure everything is tightened and secure.
Test drive the vehicle to ensure the noise has been resolved.
