Solution

1. Tire Inspection

Sub-steps:
- Remove all four tires using a lug wrench.
- Visually inspect each tire for bulges, cuts, or uneven wear patterns.
- Check the tread depth using a tread depth gauge. Replace if worn below 2/32 inches.

2. Tire Balancing

Sub-steps:
- Mount the tires on a balancing machine.
- Use weights to balance any imbalances found during the process.
- Reinstall balanced tires on the vehicle, ensuring proper torque (typically 80-100 ft-lbs).

3. Suspension and Alignment

Sub-steps:
- Inspect all suspension components for wear, including control arms and bushings.
- Replace any worn components with OEM or equivalent parts.
- Perform a wheel alignment using a professional alignment machine, adjusting camber, caster, and toe settings to manufacturer specifications.

4. Driveline Inspection

Sub-steps:
- Inspect the driveshaft for any bends or damage.
- Check CV joints for wear; replace any defective components.
- Tighten all bolts and fasteners to the specified torque settings.
