Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check tire pressures.
Inflate or deflate tires to meet manufacturer specifications as needed.

3. Tire Inspection and Rotation

Remove the hubcaps or wheel covers if applicable.
Inspect each tire for uneven wear; replace any damaged tires.
Rotate tires to ensure even wear across all tires.

4. Wheel Alignment

Position the vehicle on an alignment rack.
Adjust the toe, camber, and caster settings according to manufacturer specifications.
Tighten all adjustment bolts to the specified torque values.

5. Suspension Component Replacement (if necessary)

If any suspension components are found to be worn or damaged, replace them.
For tie rods, use a tie rod puller to remove the old tie rod and install the new one, ensuring it is adjusted to the correct length.
Replace any damaged control arms or ball joints, following manufacturer specifications for installation.
