Solution

1. Preparation

Tools Required: OBD-II scanner, fluid level dipstick, flashlight, jack stands, and socket set.
Safety Warnings: Ensure the vehicle is secured on jack stands before working underneath it. Disconnect the battery before working on electrical systems.

2. Check and Top Off Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and use a dipstick to check the fluid level.
If low, top off with the manufacturer-recommended fluid until it reaches the proper level.

3. Inspect and Replace Serpentine Belt (if needed)

Remove the engine cover (if applicable) to access the serpentine belt.
Use a belt tensioner tool to relieve tension on the belt.
Inspect the belt for cracks, fraying, or signs of wear.
If damaged, remove the old belt and install a new serpentine belt, following the routing diagram found on the engine bay.

4. Examine and Replace Wheel Bearings (if needed)

Lift the vehicle and secure it on jack stands.
Remove the wheel to access the hub assembly.
Check for any play in the wheel bearings by grasping the top and bottom of the tire and moving it.
If there is excessive play, remove the hub assembly and replace the wheel bearings following the specific service manual for torque specifications.

5. Check and Change Differential Fluid (if needed)

Locate the differential cover and remove it to access the fluid.
Inspect the fluid for metal shavings or discoloration.
If contaminated, drain the old fluid and refill with the manufacturer-specified fluid, ensuring to replace the gasket.
