3. Jack up the vehicle using a hydraulic jack and secure it with jack stands.
4. Remove the lug nuts and take off the wheel.
5. Inspect the tire for damage; replace if bulges or significant wear is found.
6. If replacing, install the new tire, ensuring the correct rotation direction. Tighten the lug nuts to the manufacturer’s specified torque.

3. Wheel Balancing

Sub-steps:
1. Mount the wheel on a balancing machine.
2. Adjust weights as needed to achieve proper balance.
3. Reinstall the balanced wheel on the vehicle, again tightening to specified torque.

4. Wheel Alignment

Sub-steps:
1. Set the vehicle on an alignment rack.
2. Adjust camber, caster, and toe settings to match manufacturer specifications.
3. Test drive the vehicle to ensure proper alignment is maintained.

5. Inspect and Replace Suspension Components (if necessary)
