Solution

1. Tire Inspection and Replacement

Sub-steps:
- Check all tires for bulges, punctures, or cuts.
- Measure tread depth and ensure even wear.
- If damaged, replace with OEM or recommended tires.

2. Wheel Balancing and Alignment

Sub-steps:
- Remove each wheel and tire assembly.
- Use a wheel balancer to balance each tire; add weights as necessary.
- Reinstall wheels and perform a four-wheel alignment using an alignment machine, adjusting camber, caster, and toe settings to manufacturer specifications.

3. Suspension Inspection and Repair

Sub-steps:
- Lift the vehicle and remove the wheel to access suspension components.
- Inspect control arms, bushings, and struts for wear and replace any damaged parts.
- Tighten all suspension bolts to manufacturer torque specifications.

4. Drivetrain Inspection and Repair

Sub-steps:
- Inspect the driveshaft and CV joints for any signs of damage or excessive play.
- If any components are worn, replace them with OEM parts.
- Ensure all drivetrain connections are secure.
