Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery if working on electronic components.

2. Lift 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 to ensure safety.

3. Inspect and Repair Suspension Components

Shock Absorbers/Struts:
- Remove the upper and lower mounting bolts using a socket set.
- Disconnect the shock absorber from the suspension assembly.
- Replace with new shock absorbers if damaged or leaking.
Sway Bar Links:
- Remove the sway bar link bolts with a wrench.
- Inspect for any wear or play; replace if necessary.
Bushings:
- Remove any components securing the bushings (e.g., control arms).
- Use a bushing removal tool to extract old bushings and install new ones.

4. Reassemble Components
