Solution

1. Preparation

Gather the necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and eye protection.

2. Tire Inspection and Replacement

Inspect Tires
- Remove any wheel covers if applicable.
- Inspect each tire for bulges, cuts, or foreign objects.
- Measure tread depth across the tire using a tread depth gauge.
Replace Tires (if necessary)
- If tires are worn beyond the tread wear indicators, replace with new tires.
- Ensure new tires are of the same size and specification as recommended by the manufacturer.

3. Wheel Balancing

Remove Wheels
- Loosen lug nuts with a socket set.
- Lift the vehicle with a jack and support it with jack stands.
- Remove the wheels from the vehicle.
Balance Wheels
- Mount the wheels on a wheel balancing machine.
- Add weights to the rim as necessary to achieve balance.
- Record the amount of weight added for each wheel.

4. Alignment Adjustment

Perform Alignment
- Reinstall wheels and torque lug nuts to specified values (typically 80-100 ft-lbs).
- Use an alignment machine to check the alignment settings.
- Adjust the camber, caster, and toe angles to match manufacturer specifications.

5. Suspension Inspection and Repair

Inspect Suspension
- Visually inspect struts, shocks, and bushings for signs of wear or damage.
- Replace any worn or damaged components, ensuring all fasteners are torqued to specifications.
