Gather safety gear (gloves, safety glasses).

2. Tire Balancing and Alignment

Sub-steps:
1. Remove the tires and wheels from the vehicle using a lug wrench.
2. Mount each wheel on a wheel balancer and check for imbalance.
3. If not balanced, add wheel weights as required.
4. Reinstall the wheels and use a torque wrench to tighten lug nuts to the manufacturer's specifications (typically 76 ft-lbs).
5. Perform a four-wheel alignment using an alignment machine, adjusting camber, caster, and toe as necessary.

3. Tire Inspection and Replacement

Sub-steps:
1. Visually inspect all tires for signs of damage or uneven wear.
2. If any tire is found to be defective, replace it with a new tire of the same size and type.
3. Ensure that the replacement tire is properly balanced before installation.
4. Reinstall the tires and torque the lug nuts.

4. Suspension and Driveline Inspection

Sub-steps:
1. Inspect all suspension components for wear, including control arms, bushings, and shocks.
2. Replace any worn or damaged parts with OEM or high-quality aftermarket components.
3. Check the driveshaft and CV joints for play or damage and replace as necessary.
