Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during any electrical work.

2. Tire Inspection and Replacement

Check Tire Condition
- Remove the wheel covers if applicable.
- Inspect each tire for bulges, cuts, or excessive wear.
Replace Damaged Tires
- If any tire is damaged, use a jack to lift the vehicle and remove the wheel.
- Install a new tire according to manufacturer specifications and torque the lug nuts to the recommended torque value (usually around 80-100 ft-lbs).

3. Wheel Balancing

Balance Tires
- Mount the wheel on a tire balancing machine.
- Adjust the weights on the wheel as needed to achieve balance.
- Reinstall the balanced wheel on the vehicle and torque the lug nuts.

4. Wheel Alignment

Perform Alignment
- Use an alignment machine to check and adjust the angles of the wheels.
- Adjust camber, caster, and toe settings to match the manufacturer's specifications.

5. Suspension Inspection and Repair

Inspect for Wear
- Visually inspect struts, shocks, control arms, and bushings for any signs of wear or damage.
Replace Worn Components
- If any suspension parts are found to be worn, replace them with new components, following manufacturer guidelines for installation and torque specifications.
