Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Safety warning: Ensure the vehicle is in gear or in 'Park' mode while working.

2. Check and Adjust Tire Pressure

Using a tire pressure gauge, check the pressure of each tire.
Inflate or deflate tires to match the manufacturer's specifications (found on the driver's door jamb).

3. Inspect and Replace Tires (if necessary)

Examine tires for signs of uneven wear.
If uneven wear is present, replace tires as needed.
Ensure all tires are of the same type and size.

4. Wheel Alignment Adjustment

Using an alignment machine, check the camber, caster, and toe angles.
Adjust the alignment according to the manufacturer's specifications using the adjustment bolts on the control arms and tie rods.

5. Inspect and Repair Suspension Components

Check bushings, ball joints, and tie rods for wear and replace any that are worn or damaged.
Tighten any loose components to the manufacturer's torque specifications.
