Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure the vehicle with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Tire Pressure Adjustment

Tools Required: Tire pressure gauge, air compressor
Check and adjust the tire pressure on all four tires to the manufacturer's specifications (usually found on the driver's door jamb).

3. Wheel Alignment

Tools Required: Alignment machine, torque wrench
Position the vehicle on the alignment rack.
Adjust the alignment settings as necessary to bring camber, toe, and caster angles within manufacturer specifications.
- Camber: Should be within -1.0 to +1.0 degrees.
- Toe: Should typically be set to 0.00 inches.
- Caster: Should be within the specified range according to the service manual.
Tighten all alignment components to the specified torque settings.

4. Suspension Component Inspection and Repair

Tools Required: Socket set, wrenches, pry bar
Inspect all suspension components such as struts, control arms, and bushings.
Replace any worn or damaged parts as necessary.
Re-torque all suspension components to manufacturer specifications.

5. Test Drive

After completing the alignment and any necessary repairs, take the vehicle for a test drive.
Ensure the vehicle tracks straight and listen for any unusual noises.
