Solution

1. Preparation

Tools Required: Safety gloves, safety glasses, jack stands, wheel chocks
Ensure the vehicle is parked on a level surface and the engine is turned off. Engage the parking brake.

2. Inspect and Replace Wheel Bearings (if necessary)

Lift Vehicle:
- Use a jack to lift the vehicle and secure it with jack stands.
Remove Wheel:
- Use a socket set to remove the lug nuts and take off the wheel.
Check Wheel Bearing:
- Spin the hub assembly by hand to listen for noise or feel for roughness. If faulty, proceed to replace.
Remove Hub Assembly:
- Remove any retaining clips or bolts securing the hub assembly. Disconnect the brake caliper if necessary.
Install New Wheel Bearing:
- Press in the new bearing using a bearing press. Reassemble the hub and wheel.

3. Check and Replace Drive Belt (if necessary)

Inspect Drive Belt:
- Visually inspect the drive belt for cracks, fraying, or excessive wear.
Remove Belt:
- Loosen the tensioner pulley and remove the belt from the pulleys.
Install New Drive Belt:
- Route the new belt according to the belt routing diagram. Reapply tension using the tensioner.

4. Transmission Fluid Check and Replacement (if necessary)

Check Fluid Level:
- Locate the transmission dipstick, remove it, and wipe clean. Reinsert and check fluid level.
Drain Old Fluid:
- Remove the transmission pan bolts and drain the fluid into a pan. Replace the transmission fluid filter if applicable.
Add New Fluid:
- Reinstall the pan with a new gasket and refill with the manufacturer-recommended transmission fluid.

5. Final Assembly and Testing

Reassemble Components:
- Reattach any components removed during inspection and repair (wheels, brake calipers, etc.).
Lower Vehicle:
- Remove jack stands and lower the vehicle back to the ground.
