Solution

1. Preparation

Tools Required: Tire pressure gauge, tread depth gauge, jack, jack stands, wheel alignment machine.
Ensure the vehicle is on a flat surface and turn off the engine.
Wear safety gloves and goggles.

2. Adjust Tire Pressure

Remove valve caps from all tires.
Use the tire pressure gauge to check the pressure of each tire.
Inflate or deflate tires to the manufacturer's recommended pressure (check the driver's side door jamb for specifications).

3. Inspect and Rotate Tires

Jack up the vehicle and secure it with jack stands.
Remove all tires from the vehicle.
Inspect each tire for uneven wear patterns and note their positions.
Rotate tires if necessary (e.g., front to back or side to side) according to the recommended pattern for your vehicle.

4. Align Wheels

Mount the vehicle on a wheel alignment machine.
Adjust the camber, caster, and toe settings to align with manufacturer specifications.
Tighten all adjustment bolts to the specified torque values.

5. Inspect Suspension Components

Check all suspension components for wear or damage.
Replace worn parts as necessary (e.g., control arms, bushings, or struts).
