Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Tire Inspection and Repair

Check Tire Condition:
- Inspect each tire for visual damage (bulges, cracks).
- Use a tread depth gauge to ensure tread depth is adequate.
Replace Tires (if necessary):
- Remove the wheel using a lug wrench.
- Install new tires according to manufacturer specifications.
- Torque lug nuts to the specified value (typically 80-100 ft-lbs).

3. Tire Balancing

Balance Tires:
- Mount tires on a balancing machine.
- Add wheel weights as needed to achieve balance.

4. Suspension Inspection

Inspect Components:
- Visually inspect shocks/struts for leaks and physical damage.
- Use a pry bar to assess bushing integrity; replace worn components as necessary.

5. Wheel Alignment

Perform Alignment:
- Use an alignment rack to check and adjust camber, caster, and toe settings.
- Adjust settings according to the manufacturer's specifications.
