Solution

1. Preparation

Tools Required:
- Socket set
- Pliers
- Fluid catch pan
- Torque wrench
Ensure the vehicle is parked on a flat surface and turn off the engine. Allow the engine to cool before beginning any work.

2. Check and Top Off Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level. If low, proceed to the next step.
Use a clean funnel to add the appropriate power steering fluid (refer to owner’s manual for specifications) until it reaches the correct level.
Replace the cap securely.

3. Inspect and Replace Power Steering Pump (if necessary)

Tools Required:
- Wrench set
- Screwdrivers
Disconnect the battery to prevent electrical shorts.
Remove any components obstructing the power steering pump.
Disconnect the power steering lines from the pump using the wrench. Be cautious of fluid spillage.
Remove the mounting bolts securing the pump to the engine and take out the pump.
Install the new power steering pump by reversing the removal steps, ensuring proper torque on the mounting bolts as specified in the service manual.

4. Inspect and Replace Wheel Bearings (if necessary)

Tools Required:
- Jack and jack stands
- Bearing puller
- Torque wrench
Lift the front of the vehicle and secure it on jack stands.
Remove the front wheel to access the hub assembly.
Check for any play in the wheel by rocking it back and forth. If there's excessive movement, the bearings may need replacement.
Use the bearing puller to remove the old bearings and install new ones, ensuring they are properly seated and lubricated.

5. Check Serpentine Belt Tension and Condition

Inspect the serpentine belt for cracks, fraying, or glazing.
Ensure the belt tension is within specifications. Adjust or replace if necessary, following the routing diagram typically found on the engine bay.
