Solution

1. Tire Inspection and Balancing

Sub-steps:
- Remove the wheels from the vehicle using a socket set.
- Inspect each tire for uneven wear, bulges, or punctures.
- Take the tires to a tire shop for balancing; they will adjust weights as necessary.
- Reinstall the tires and torque the lug nuts to the manufacturer's specifications (usually 80-100 ft-lbs).

2. Wheel Alignment

Sub-steps:
- If uneven tire wear is observed, schedule a wheel alignment.
- The technician will adjust the camber, caster, and toe angles according to factory specifications.
- Verify that steering wheel is centered post-adjustment.

3. Suspension Component Check

Sub-steps:
- Inspect all suspension components visually for cracks, wear, or damage.
- Replace any worn bushings, shocks, or struts as necessary.
- Tighten all suspension bolts to the specified torque values.

4. Driveshaft and U-Joint Inspection

Sub-steps:
- Lift the vehicle and remove the driveshaft by unbolting the U-joints.
- Inspect the U-joints for stiffness or play and replace if necessary.
- Reinstall the driveshaft and ensure all bolts are torqued to specifications.

5. Wheel Bearing Inspection

Sub-steps:
- Jack up the vehicle and rotate each wheel to check for noise or roughness.
- If play is detected, remove the wheel and hub assembly, and replace the bearing.
- Grease the new bearing appropriately and reassemble.
