Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal.

2. Inspect and Replace Serpentine Belt

Sub-steps:
1. Locate the serpentine belt routing diagram (usually found on a sticker in the engine bay).
2. Use a socket wrench to release tension from the tensioner pulley and remove the belt.
3. Inspect the belt for cracks, fraying, or glazing; replace if any damage is found.
4. Install the new belt by following the routing diagram, ensuring it sits properly on all pulleys.
Tools Required: Socket set, serpentine belt tool (optional).

3. Check and Replace Wheel Bearings (if necessary)

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the hub assembly.
3. Inspect the wheel bearing for play by shaking the hub; replace if excessive movement is noted.
4. If replacement is needed, remove the hub assembly and replace the bearing using a bearing puller.
Tools Required: Jack, jack stands, wheel bearing puller, socket set.

4. Inspect Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick (if equipped) or check the fill plug.
2. Remove the dipstick or fill plug and check fluid level and condition (should be red and clear).
3. If low, add the appropriate transmission fluid as specified in the owner’s manual. If dirty, consider a transmission fluid change.
Tools Required: Funnel, transmission fluid.
