Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface.
Use wheel chocks to prevent movement.

Tools Required:

Tire pressure gauge
Tread depth gauge
Alignment machine
Jack and jack stands
Socket set

2. Adjust Tire Pressure

Sub-step 1: Use the tire pressure gauge to check the pressure of each tire.
Sub-step 2: Inflate or deflate tires to the manufacturer’s recommended pressure (found in the driver’s side door jamb).

3. Rotate Tires

Sub-step 1: Loosen the lug nuts on all four tires using the socket set.
Sub-step 2: Lift the vehicle with a jack and secure it with jack stands.
Sub-step 3: Remove the tires and rotate them according to a standard rotation pattern (e.g., front to back and side to side).
Sub-step 4: Reinstall the tires and tighten the lug nuts to the manufacturer’s specified torque value.

4. Perform Wheel Alignment

Sub-step 1: Take the vehicle to a professional alignment shop or use an alignment machine if available.
Sub-step 2: Adjust camber, caster, and toe angles to meet factory specifications as indicated in the service manual.

5. Inspect and Replace Suspension Components (if necessary)

Sub-step 1: If any damaged suspension components (e.g., control arms, bushings) are found during the inspection, replace them.
Sub-step 2: Follow the manufacturer's instructions for disassembly and reassembly, ensuring all fasteners are torqued to specification.
