Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely raised using jack stands.

2. Tire Inspection and Replacement

Check Tire Pressure:
- Use a tire pressure gauge to measure PSI.
- Inflate tires to the manufacturer’s recommended pressure if necessary.
Inspect for Uneven Wear:
- Look for bald spots or uneven tread depth.
- Replace any damaged or excessively worn tires.

3. Wheel Balancing

Remove Wheels:
- Loosen lug nuts and remove the wheels using a socket set.
Balance Wheels:
- Mount the wheels on a wheel balancer.
- Add wheel weights as needed to achieve balance.
- Reinstall wheels and torque lug nuts to the manufacturer's specifications (typically 80-120 ft-lbs).

4. Suspension Inspection and Repair

Inspect Suspension Components:
- Check bushings, control arms, and struts for any signs of wear or damage.
Replace Worn Components:
- If any parts are worn, remove and replace them with new parts using appropriate tools.

5. Driveshaft and U-joint Check

Inspect Driveshaft:
- Look for any signs of damage or excessive play.
Replace U-joints if Necessary:
- Remove the driveshaft and replace U-joints that show wear.

6. Wheel Alignment

Perform Alignment:
- Use a wheel alignment machine to check and adjust the alignment as required.
