Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety: Wear gloves and safety glasses.

2. Raise the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on where the noise is originating.
Secure the vehicle with jack stands.

3. Inspect and Replace Components

A. Inspect Suspension Components

Examine the struts and shocks for leaks or damage.
- If damaged, proceed to replace.

B. Replace Sway Bar Links

If sway bar links are worn, remove the bolts securing them using a socket set.
Install new sway bar links by aligning them with the mounting holes and tightening to manufacturer specifications (usually 25-30 ft-lbs).

C. Check Control Arms

If control arms are worn, remove the bolts using a socket set.
Replace with new control arms and tighten the bolts to the specified torque (typically around 80-100 ft-lbs).

4. Reassemble and Lower Vehicle

Reattach any components removed for inspection.
Lower the vehicle back to the ground and remove jack stands.
