Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, mechanic's stethoscope, inspection mirror.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheels to gain access to the suspension components.

2. Inspect and Replace Worn Components

Examine Struts and Shocks:
- Check for oil leakage on struts or shocks.
- If leaking, remove the strut assembly by loosening the upper strut mount bolts and lower control arm bolts.
- Replace with new strut/shock absorbers.
Inspect Bushings and Mounts:
- Look for cracks or excessive wear in rubber bushings and mounts.
- Use a pry bar to check for play in the bushings.
- If worn, remove the affected components and replace with new bushings or mounts.

3. Reassemble Suspension

Reinstall Components:
- Torque all bolts to manufacturer specifications using a torque wrench.
- Ensure proper alignment of all suspension components.

4. Test Drive

Lower the vehicle and perform a test drive to ensure the noise is resolved and the vehicle handles properly.
