Solution

1. Preparation

Tools Required: Jack and jack stands, OBD-II scanner, socket set, fluid pump, transmission fluid, funnel.
Ensure the vehicle is parked on a level surface, and engage the parking brake. Allow the engine to cool before starting work.

2. Inspect and Replace Transmission Fluid

Check Fluid Level: Using the dipstick (if applicable), ensure the transmission fluid is at the correct level.
Drain Old Fluid: If the fluid is low or dirty, use a fluid pump to drain the existing transmission fluid into a suitable container.
Replace Filter (if applicable): If your model has a replaceable filter, remove the old filter and install a new one according to the manufacturer’s specifications.
Add New Fluid: Using a funnel, add the recommended type and amount of transmission fluid. Refer to the owner's manual for specific fluid type and capacity.
Check for Leaks: Start the engine and let it run for a few minutes while checking for any leaks around the transmission area.

3. Inspect and Replace Drive Belts

Visual Inspection: Check the drive belts for cracks, fraying, or signs of wear.
Remove Tension: Use a belt tensioner tool or ratchet to relieve tension on the serpentine belt.
Replace Belt: Remove the old belt and install a new one, ensuring it is routed according to the belt diagram.
Reapply Tension: Reapply tension to the belt and ensure it is securely in place.

4. Wheel Bearing Inspection and Replacement

Lift Vehicle: Use a jack to lift the vehicle and secure it with jack stands.
Remove Wheel: Take off the wheel to access the hub assembly.
Check Bearings: Spin the hub and listen for any grinding or roughness; replace if necessary.
Replace Bearings: If needed, remove the hub assembly and press out the old bearings. Install new bearings and reassemble.
