Solution

1. Tire Inspection

Sub-steps:
1. Check all tires for uneven wear patterns or bulges.
2. Measure tire pressure and adjust to specifications found in the owner’s manual.
3. If any tires are damaged or excessively worn, replace them.

2. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a socket set.
2. Mount the wheels on a tire balancing machine.
3. Add weights as necessary to ensure the wheels are balanced to manufacturer specifications.
4. Reinstall the wheels and torque the lug nuts to the recommended specifications (typically 100-120 Nm).

3. Suspension Inspection

Sub-steps:
1. Raise the vehicle using a hydraulic lift or jack stands.
2. Inspect all suspension components (control arms, bushings, shocks/struts) for signs of wear or damage.
3. Replace any worn or damaged parts with OEM or equivalent parts.

4. Wheel Alignment

Sub-steps:
1. After ensuring tire and wheel conditions are satisfactory, perform a four-wheel alignment.
2. Adjust camber, caster, and toe settings to match manufacturer specifications.
3. Test drive the vehicle to confirm that the alignment is correct.

5. Drivetrain Inspection

Sub-steps:
1. Inspect drive shafts and CV joints for any signs of wear or damage.
2. Check for any play in the differential or transmission mounts.
3. Repair or replace any faulty components found during inspection.
