Safety first: wear safety glasses and gloves.

2. Inspect and Replace Suspension Components

Raise the Vehicle:
- Use a hydraulic jack to lift the vehicle and secure it on jack stands.
- Ensure the vehicle is stable before proceeding.
Check Shock Absorbers:
- Remove the bolts securing the shock absorbers to the lower control arm and upper mount using a socket set.
- Inspect the shocks for leaks or damage; replace them if necessary.
Inspect Control Arm Bushings:
- Use a pry bar to check for play in the control arm bushings.
- If they are worn, remove the control arm by unbolting it from the frame and axle, then replace the bushings or control arm as needed.
Check and Replace Body Mounts:
- Inspect body mounts for cracks or deterioration.
- If needed, unbolt the body mounts and replace with new mounts, ensuring proper alignment.
Reassemble and Lower the Vehicle:
- Reattach all components securely following manufacturer torque specifications.
- Remove jack stands and lower the vehicle.
