2. Tire Inspection and Replacement

Inspect Tires:
- Check for uneven wear, bulges, or damage.
- Measure tire pressure and inflate to the recommended PSI.
Replace Tires (if necessary):
- Loosen lug nuts with a socket set.
- Lift the vehicle using a jack and secure with jack stands.
- Remove the wheels and replace with new tires.
- Tighten lug nuts to the manufacturer's specified torque value.

3. Wheel Balancing

Balance Wheels:
- Mount the wheels on a wheel balancer.
- Follow the machine’s instructions to add weights as needed.
- Reinstall balanced wheels on the vehicle.

4. Driveshaft and U-Joint Inspection

Inspect Driveshaft:
- Check for any signs of damage or bent sections.
- Inspect U-joints for play or damage; replace if necessary.
Replace U-Joint (if needed):
- Remove the driveshaft by unbolting it from the differential and transmission.
- Use a U-joint press to remove the old U-joint and install a new one.
- Reinstall the driveshaft and secure it.

5. Wheel Alignment

Perform Alignment:
- Use an alignment machine to check all alignment angles.
- Adjust camber, toe, and caster angles to meet manufacturer specifications.
