Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, flashlight
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to ensure safety while performing repairs.

2. Inspect and Replace Serpentine Belt

Remove the engine cover if applicable.
Use a socket wrench to relieve tension on the serpentine belt tensioner.
Carefully remove the belt from the pulleys.
Inspect the belt for any visible signs of wear or damage.
If damaged, replace with a new serpentine belt, ensuring it is routed correctly over all pulleys.
Reattach the engine cover if removed.

3. Check and Replace Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission drain plug and allow the fluid to drain completely.
Replace the drain plug and torque to the manufacturer's specifications.
Refill the transmission with the manufacturer-recommended fluid using a funnel.
Start the engine and cycle through all gears to circulate the new fluid. Check the fluid level and adjust as necessary.

4. Inspect Power Steering System

Check the power steering fluid level in the reservoir.
If low, add the appropriate power steering fluid until it reaches the recommended level.
Inspect hoses and connections for any signs of leakage and replace any damaged components.

5. Wheel Bearing and Differential Inspection

Lift the vehicle and secure it on jack stands.
Spin each wheel and listen for any grinding or abnormal noises indicating a bad wheel bearing.
Inspect the differential for fluid leaks or noise when the vehicle is in motion.
Replace any faulty wheel bearings or differential components as necessary.
