Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is coming from.
Secure the vehicle with jack stands for safety.

3. Inspect and Replace Suspension Components

Struts/Shocks Replacement:
1. Remove the wheel to access the strut assembly.
2. Disconnect the strut from the lower control arm by removing the bolt (use a socket set).
3. Remove the upper strut mounting bolts (usually located in the engine bay).
4. Replace the strut/shock absorber with a new unit, ensuring proper alignment.
5. Torque the upper and lower mounting bolts to manufacturer specifications (usually around 50-60 ft-lbs).
Sway Bar Links Replacement:
1. Locate the sway bar links connecting the sway bar to the control arm.
2. Remove the nuts securing the links using a socket.
3. Replace with new sway bar links and torque to specifications (typically 35-40 ft-lbs).

4. Reassemble and Lower Vehicle

Reinstall the wheel and tighten lug nuts to the manufacturer’s torque specification (usually 76-83 ft-lbs).
Lower the vehicle and remove jack stands.
