Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, and a rubber mallet.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if electrical components are involved.

2. Inspect and Replace Worn Components

Shock Absorbers/Struts:
1. Remove the wheel to access the suspension.
2. Unbolt the shock absorber or strut from the top mount and lower control arm.
3. Inspect for leaks or physical damage; replace if necessary.
4. Install new shock absorbers or struts and torque to manufacturer specifications.
Sway Bar Links:
1. Locate the sway bar and inspect the links.
2. Remove the sway bar link bolts using the socket set.
3. Replace with new sway bar links and torque to specifications.
Control Arms and Bushings:
1. If the control arms are worn, unbolt them from the chassis and the knuckle.
2. Replace with new control arms, ensuring all bushings are secured.
3. Torque all bolts according to manufacturer specs.

3. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Reconnect the battery if previously disconnected.
Perform a road test to ensure the noise has been resolved.
