Solution

1. Preparation

Gather tools and parts needed for inspection and repair.
Tools Required: Jack, jack stands, lug wrench, torque wrench, screwdriver set, multimeter (optional).
Wear safety glasses and gloves.

2. Tire Inspection and Replacement

Sub-steps:
1. Check tire pressure using a tire gauge; inflate or deflate as necessary to meet manufacturer specifications.
2. Inspect each tire for signs of uneven wear or damage. Replace any tires that are worn beyond safety limits.
3. If replacement is needed, remove wheel nuts using a lug wrench, lift the vehicle, and replace with new tires.
4. Torque wheel nuts to manufacturer specifications (typically around 80-100 ft-lbs).

3. Wheel Bearing Inspection and Replacement

Sub-steps:
1. Lift the vehicle securely on jack stands and remove the wheel.
2. Inspect the wheel bearing by rotating the hub; listen for roughness or grinding sounds.
3. If bearing is faulty, remove the brake caliper and rotor, then disconnect the hub assembly.
4. Replace the wheel bearing with a new part, ensuring proper alignment.
5. Reassemble the hub, brake rotor, and caliper. Torque all components to specifications.

4. Drivetrain Inspection

Sub-steps:
1. Examine the driveshaft for any signs of damage or wear.
2. Inspect the differential for leaks or unusual noise when rotated by hand.
3. If issues are found, replace the affected components, ensuring proper lubrication and alignment.
