Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, socket set, torque wrench, OBD-II scanner.
Ensure the vehicle is on a flat surface and secure it with wheel chocks. Raise the vehicle using a jack and support it with jack stands.

2. Brake Inspection and Replacement

Remove the wheel to access the brake assembly.
Inspect brake pads for thickness; if worn below the manufacturer’s specification, replace them.
Check the rotors for scoring or warping. If necessary, replace or resurface them.
Reinstall the wheel and torque to manufacturer specifications.

3. Wheel Bearing Inspection and Replacement

Spin the wheel manually to check for any grinding noises or roughness.
If the bearing is faulty, remove the wheel, brake assembly, and hub assembly.
Replace the wheel bearing and reassemble components, ensuring to torque all bolts to specifications.

4. Driveshaft Inspection and Repair

Inspect the driveshaft for any visible damage or bent sections.
Check the U-joints for any play; if damaged, replace them.
Reinstall the driveshaft and ensure all bolts are tightened to specifications.

5. Differential Fluid Check and Service

Locate the differential cover and remove the fill plug.
Check the fluid level and condition; if it appears dirty or contains metal shavings, drain and replace it with the appropriate fluid.
Refill to the correct level and reinstall the fill plug.
