Solution

1. Preparation

Gather tools and necessary replacement parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Use wheel chocks for safety.

2. Inspect and Replace Worn Suspension Components

Remove the Wheel:
- Use a lug wrench to loosen lug nuts.
- Safely lift the vehicle using a jack and secure it with jack stands.
- Remove the lug nuts and take off the wheel.
Inspect Struts and Shocks:
- Check for oil leakage on struts or shocks, indicating failure.
- Look for visible damage to mounting points and bushings.
Replace Damaged Components:
- If struts or shocks are damaged, remove the top bolts and lower bolts using a socket set.
- Install new struts or shocks in reverse order, ensuring to torque bolts to manufacturer specifications.

3. Inspect and Tighten Exhaust Components

Examine Exhaust System:
- Check for loose hangers or brackets.
- Tighten any loose bolts or replace broken hangers as necessary.

4. Inspect Wheel Bearings

Check for Play:
- With the wheel still off, grab the hub and shake it to check for movement.
- If there is noticeable play, replace the wheel bearing.

5. Reassemble Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications.
