Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Raise the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, then secure it with jack stands.
Ensure the vehicle is stable before working underneath.

3. Inspect and Replace Suspension Components

Struts/Shocks:
- Remove the wheel to access the strut assembly.
- Unbolt the strut from the lower control arm and upper mount.
- Inspect for leaks or damage; replace if necessary.
Control Arm Bushings:
- Remove the control arm if bushings are worn.
- Use a press to replace bushings; torque the control arm bolts to manufacturer specifications upon reinstallation.

4. Check Exhaust System

Inspect the exhaust for loose hangers or contact points with the undercarriage.
Tighten or replace any loose components.

5. Reassemble and Lower the Vehicle

Reinstall the wheel and lower the vehicle from the jack stands.
Tighten lug nuts to the specified torque.
