2. Remove Component

Raise the Vehicle: Use the jack to lift the vehicle and secure it with jack stands.
Remove Wheel: Take off the wheel to access the suspension components.
Disconnect Components: If necessary, disconnect any components that obstruct access to the suspension part being repaired (e.g., sway bar links, brake lines).

3. Inspect and Replace

Inspect Components: Check the struts, shocks, and bushings for damage. Look for leaks in the shocks.
Replace Worn Parts: If any components are found to be worn or damaged, replace them with new parts.
- Part Example: Struts, shocks, bushings, control arms.
Reassemble Components: Reattach all components in reverse order of removal, ensuring to torque bolts to specifications.

4. Alignment

Perform Wheel Alignment: Use an alignment tool to adjust the wheels to the manufacturer’s specifications.
Road Test: Take the vehicle for a test drive to ensure the noise has been resolved.
