Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.

2. Tire Inspection and Replacement

Check Tire Pressure
- Use a tire pressure gauge to measure all tire pressures and inflate to the recommended levels if necessary.
Inspect Tires for Damage
- Examine each tire for bulges, cracks, or uneven wear; replace any damaged tires with suitable replacements.

3. Wheel Balancing

Remove Wheels
- Use a socket set to remove the lug nuts and take off the wheels.
Balance Wheels
- Mount the wheels on a balancing machine and add weights as needed to achieve balance.

4. Wheel Alignment

Set Up Alignment Equipment
- Position alignment racks and sensors to measure the current alignment settings.
Adjust Alignment
- Follow manufacturer specifications to adjust camber, caster, and toe settings, ensuring they are within the acceptable range.

5. Suspension Check and Repair

Inspect Suspension Components
- Visually inspect and use a pry bar to check for play in control arms, ball joints, and bushings.
Replace Worn Components
- Replace any worn or damaged parts, using manufacturer-recommended parts and torque specifications during reassembly.
