Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and is secure.
Wear safety gloves and goggles.

2. Tire Rotation

Sub-steps:
1. Loosen lug nuts on all four wheels slightly without removing them.
2. Raise the vehicle using a hydraulic jack and secure it on jack stands.
3. Remove the lug nuts and take off the tires.
4. Rotate the tires according to the recommended pattern (e.g., front to rear and vice versa).
5. Reinstall the tires and hand-tighten the lug nuts.

3. Wheel Alignment

Sub-steps:
1. Using a wheel alignment machine, ensure the vehicle is on a level surface.
2. Adjust the camber, caster, and toe settings to the manufacturer's specifications (consult the service manual for specific values).
3. After adjustments, confirm the alignment settings are within acceptable limits.

4. Suspension Inspection and Repair

Sub-steps:
1. Inspect all suspension components (control arms, bushings, struts, etc.) for wear or damage.
2. Replace any worn or damaged components using appropriate tools (socket set, torque wrench).
3. Ensure that all fasteners are torqued to the manufacturer's specifications.

5. Balance Wheels

Sub-steps:
1. Remove each wheel and place it on a balancing machine.
2. Adjust the weights on the rim as needed to achieve balance.
3. Reinstall the balanced wheels on the vehicle.
