Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, alignment machine (if available).
Safety Warnings: Always ensure the vehicle is on a flat surface and securely supported by jack stands before working underneath.

2. Tire Rotation

Sub-steps:
1. Loosen the lug nuts on all four tires using a lug wrench but do not remove them completely.
2. Use a jack to lift the vehicle and secure it on jack stands.
3. Remove the lug nuts and take off the tires.
4. Rotate the tires to the recommended positions (front tires to the back and vice versa, swapping sides for non-directional tires).
5. Reinstall the lug nuts and torque them to the manufacturer’s specifications (usually 80-100 ft-lbs for most vehicles).

3. Wheel Alignment

Sub-steps:
1. If you have access to an alignment machine, set the vehicle on the machine and follow the manufacturer’s instructions.
2. Adjust the camber, caster, and toe angles to meet the vehicle specifications.
3. If no machine is available, take the vehicle to a professional alignment shop.

4. Suspension Inspection and Repair

Sub-steps:
1. Inspect all suspension parts for wear, including control arms, ball joints, and bushings.
2. Replace any worn or damaged components with OEM or quality aftermarket parts.
3. Recheck alignment after any suspension component replacements.
