Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery for safety before performing electrical work.

2. Inspect and Replace Serpentine Belt

Remove the engine cover (if applicable) using a socket set.
Loosen the tensioner using a wrench to relieve tension on the serpentine belt.
Remove the serpentine belt and inspect for cracks, fraying, or glazing.
Replace with a new serpentine belt, ensuring it is routed correctly according to the belt diagram.
Re-tension the belt and secure the tensioner back in place.

3. Check and Replace Transmission Fluid

Locate the transmission fluid dipstick and check fluid levels.
If low, drain the old transmission fluid using a drain pan and a wrench.
Replace the transmission fluid filter if applicable, by removing the pan and replacing the filter.
Refill with new transmission fluid as per manufacturer specifications.
Check for leaks after refilling.

4. Inspect Wheel Bearings

Lift the front or rear of the vehicle using a jack and secure it with jack stands.
Remove the wheel using a socket set.
Inspect the wheel bearings for any signs of damage or excessive play. Spin the hub and listen for noise.
If damaged, replace the wheel bearings by pressing out the old bearings and installing new ones.
