Solution

1. Preparation

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

2. Inspect and Replace Suspension Components

Lift the Vehicle: Use a jack to lift the vehicle and secure it with jack stands.
Remove Wheels: Take off the front or rear wheels, depending on where the noise is originating.
Check Suspension Parts:
- Inspect struts and shocks for leaks or physical damage.
- Look for worn bushings in control arms; replace if cracked or excessively worn.
Replace Damaged Components:
- If any components are damaged, remove and replace them. Use a socket set to remove nuts and bolts.
- Torque new components to manufacturer specifications (check the vehicle's service manual for exact torque values).

3. Inspect and Replace Drivetrain Components

Inspect CV Joints: Check for any tears in the CV boot or play in the joints.
Replace if Necessary:
- If CV joints are damaged, remove the axle from the hub and replace the entire axle assembly.
- Ensure you use new axle nuts and torque them to specifications.
Reassemble: Reattach the wheels and lower the vehicle.
