Solution

1. Preparation

Tools Required: Tire pressure gauge, floor jack, jack stands, lug wrench, wheel balancer, alignment machine.
Ensure vehicle is on a level surface and allow the engine to cool if necessary.

2. Tire Inspection and Balancing

Sub-steps:
1. Check and adjust tire pressure to the recommended PSI.
2. Remove the tires using a lug wrench and inspect for any visible damage.
3. Mount the tires on a wheel balancer to check for imbalance and adjust as necessary.
4. Reinstall tires and torque lug nuts to the manufacturer’s specifications (typically 100-150 ft-lbs).

3. Wheel Alignment

Sub-steps:
1. Position the vehicle on an alignment rack.
2. Adjust the camber, caster, and toe settings according to the manufacturer's specifications.
3. Perform a test drive to ensure the steering wheel is centered.

4. Suspension and Drivetrain Inspection

Sub-steps:
1. Visually inspect suspension components for any signs of wear or damage.
2. Replace any worn parts such as bushings or ball joints.
3. Inspect the driveshaft and U-joints for any signs of wear; replace if necessary.
