Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Inspection and Replacement (if necessary)

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench
Steps:
1. Use a tire pressure gauge to check all tire pressures; inflate as needed to the recommended PSI.
2. Inspect tires for uneven wear; if any tires are severely worn, replace them.
3. If replacing tires, lift the vehicle using a jack, secure it with jack stands, and use a lug wrench to remove the tires.

3. Suspension Component Inspection and Replacement

Tools Required: Socket set, torque wrench, pry bar
Steps:
1. Visually inspect all suspension components, including control arms, struts, and bushings, for signs of wear or damage.
2. Replace any damaged components; consult the service manual for specific torque settings during reinstallation.
3. Ensure the vehicle is aligned after any suspension work.

4. Drive Shaft and CV Joint Inspection and Replacement

Tools Required: Socket set, torque wrench
Steps:
1. Inspect the drive shafts and CV joints for any visible damage or excessive play.
