Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid catch pan, funnel, multimeter, jack and jack stands.
Safety Warnings: Disconnect the battery before working on electrical components. Allow the engine to cool before inspecting any belts or fluid systems.

2. Power Steering Fluid Inspection

Locate the power steering reservoir.
Remove the cap and check the fluid level against the markings on the reservoir.
If low, top off with manufacturer-recommended power steering fluid.
If the fluid is dirty or foamy, drain and replace it:
- Use a fluid catch pan to collect old fluid.
- Refill with new fluid and bleed the system as necessary.

3. Serpentine Belt Replacement

Release tension on the serpentine belt using a belt tensioner tool.
Remove the old belt and inspect pulleys for wear.
Install the new serpentine belt according to the routing diagram located under the hood.
Ensure the belt is seated properly on all pulleys and recheck tension.

4. Differential Fluid Change

Lift the vehicle securely and remove the differential cover bolts.
Allow old fluid to drain completely into a catch pan.
Inspect the differential gears for wear; replace if necessary.
Reinstall the cover using a new gasket or sealant as required.
Fill with the manufacturer-recommended differential fluid until it reaches the fill hole level.

5. Wheel Bearing Inspection

Jack up the vehicle and remove the wheel for access.
Inspect the wheel bearings for play by shaking the wheel; if there’s excessive play, they may need to be replaced.
If damaged, remove the hub assembly and replace the wheel bearings using a press.
