Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative terminal of the battery if necessary.

2. Tire Pressure Check

Use a tire pressure gauge to measure the pressure of each tire.
Inflate tires to the recommended pressure as found in the owner’s manual or on the driver's side door jamb.

3. Tire Inspection and Replacement

Remove any damaged or unevenly worn tires.
Replace with new or properly balanced tires if necessary.
Ensure that all tires are the same type and size for optimal performance.

4. Wheel Balancing

Mount tires on a wheel balancing machine.
Follow machine instructions to balance each tire.
Ensure weights are properly placed to achieve balance.

5. Wheel Alignment

Use an alignment machine to check and adjust the wheel alignment.
Adjust camber, caster, and toe settings to meet manufacturer specifications.
Torque bolts to the recommended values as specified in the service manual.

6. Suspension Component Inspection

Inspect all suspension components for signs of wear or damage.
Replace any worn parts, such as tie rods or ball joints, following manufacturer specifications.
Reassemble any components removed during inspection.
