Solution

1. Preparation

Tools Required: Tire pressure gauge, jack and jack stands, alignment machine, torque wrench, impact wrench.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Tire Pressure Adjustment

Using the tire pressure gauge, check the pressure of all four tires.
Inflate or deflate each tire to the manufacturer's recommended pressure (found on the driver’s door jamb).
Recheck the pressure to ensure accuracy.

3. Tire Inspection and Rotation

Visually inspect each tire for signs of uneven wear, bulges, or cuts.
If uneven wear is detected, rotate the tires according to the recommended rotation pattern.
Replace any damaged tires before proceeding.

4. Wheel Alignment

Using the alignment machine, check the alignment settings for camber, caster, and toe.
Adjust the alignment settings as follows:
- Camber: Adjust to manufacturer specifications (typically between -0.5° to +0.5°).
- Caster: Should be within the manufacturer’s specified range (usually 3° to 7°).
- Toe: Adjust to between 0° and 1/8” toe-in.
Tighten all adjustment bolts to the specified torque values (refer to the service manual for exact values).

5. Suspension Component Check

Inspect the control arms, bushings, and tie rods for wear or damage.
Replace any worn or damaged parts as necessary.
