Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, serpentine belt tool, fluid pump, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical accidents.

2. Replace Serpentine Belt (if worn)

Remove the old belt:
- Use the serpentine belt tool to relieve tension on the tensioner pulley.
- Carefully slide the belt off the pulleys.
Install the new belt:
- Route the new belt according to the belt routing diagram (usually found on the engine cover or in the owner’s manual).
- Reapply tension on the tensioner to secure the belt in place.
Double-check the installation to ensure the belt is aligned properly on all pulleys.

3. Fluid Check and Replacement

Check transmission fluid:
- With the vehicle on level ground, remove the transmission dipstick (if applicable).
- Inspect fluid color and level; it should be bright red and at the correct level.
- If low, add the manufacturer-recommended transmission fluid.
Check power steering fluid:
- Inspect the power steering reservoir; ensure fluid is at the designated level.
- If low, fill with the appropriate power steering fluid.

4. Inspect and Repair Wheel Bearings

Lift the vehicle using a jack and secure with jack stands.
Spin each wheel to listen for grinding or abnormal noises.
Replace any defective wheel bearings:
- Remove the wheel and brake assembly.
- Use a bearing puller to remove the old bearing and install the new one.
- Reassemble the brake assembly and wheel.

5. Differential Inspection

Check the differential fluid:
- Remove the differential cover or fill plug to inspect fluid level and condition.
- Replace any low or contaminated fluid with the correct type.
Inspect for leaks around the seals and housing.
