Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Jack up the vehicle and secure it on jack stands.
Remove the wheel to access the suspension components.

3. Inspect and Replace Components

Shock Absorbers/Struts:
- If leaking or damaged, remove the top and bottom bolts using a socket set.
- Replace with new shock absorbers or struts, ensuring to torque bolts to manufacturer specifications (e.g., 35-50 ft-lbs).
Sway Bar Links:
- Remove the sway bar link bolts with a wrench, inspect for play.
- Replace if worn, ensuring new links are tightened to manufacturer's torque specs (typically around 30-40 ft-lbs).
Bushings:
- Remove any brackets holding bushings, using a pry bar if necessary.
- Replace with new bushings, lubricating as required, and reassemble brackets to manufacturer torque specifications.

4. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).
Conduct a test drive to ensure the noise has been resolved.
