Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Tire Inspection and Replacement

Inspect Tires:
- Check for bulges, cuts, or punctures on the tire surface.
- Measure tread depth; if below 2/32 inch, replace tires.
Replace Tires (if necessary):
- Loosen lug nuts with a socket set.
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the lug nuts and take off the tire.
- Install new tire, hand-tighten lug nuts, lower the vehicle, and torque lug nuts to 76 ft-lbs.

3. Suspension Component Replacement

Inspect and Replace Damaged Components:
- Check struts and shocks for leaks or damage; replace if necessary.
- Remove damaged strut/shock using a socket set.
- Install new strut/shock in reverse order and torque bolts to manufacturer specifications (typically around 50-70 ft-lbs for strut assembly).
- Inspect and replace any worn bushings or control arms as needed.

4. Wheel Bearing and Driveshaft Inspection

Inspect Wheel Bearings:
- Raise the vehicle and spin each wheel; listen for grinding noises.
- If a bearing is bad, remove the wheel and hub assembly, replace the bearing, and reassemble.
Inspect Driveshaft and CV Joints:
- Check CV boots for tears and ensure there’s no play in the joints.
- Replace any damaged CV joints or driveshaft if necessary.
