Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and parts.

2. Inspect and Replace Serpentine Belt

Tools Required: Socket set, belt tensioner tool.
Check the condition of the serpentine belt for cracks or fraying.
If damaged, release the tension on the belt using the tensioner tool and remove the old belt.
Install the new serpentine belt according to the routing diagram (usually found in the engine bay).
Reapply tension and ensure the belt is seated correctly.

3. Check and Refill Power Steering Fluid

Tools Required: Clean funnel, power steering fluid.
Remove the power steering fluid reservoir cap and check the fluid level.
If low, add the appropriate type of power steering fluid as per the owner’s manual.
Inspect hoses for leaks and replace if necessary.

4. Inspect Transmission Fluid

Tools Required: Transmission dipstick (if applicable), funnel.
Check the transmission fluid level using the dipstick (if equipped).
If the fluid is low or discolored, drain and replace with the manufacturer-recommended transmission fluid.

5. Inspect Wheel Bearings

Tools Required: Jack, jack stands, wheel chocks, socket set.
Lift the vehicle and remove the wheel to expose the hub.
Check for play in the wheel by shaking it at 12 and 6 o'clock positions.
If noise is heard while rotating the hub, replace the wheel bearing.
