Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Inspect and Replace Serpentine Belt

Sub-steps:
- Locate the serpentine belt routing diagram (usually found on a sticker under the hood).

- Inspect the pulleys for wear or damage.
- Install the new serpentine belt according to the routing diagram.
Tools Required: Socket set, serpentine belt tool
Safety Warnings: Ensure engine is off and cool before working on the belt.

3. Check and Replace Power Steering Pump (if defective)

Sub-steps:
- If diagnosed, remove the power steering fluid reservoir cap and check for fluid levels.
- Disconnect the battery to ensure safety.
- Remove the serpentine belt again if it’s obstructing access.
- Unscrew the power steering pump mounting bolts and disconnect the fluid lines (be prepared for fluid spillage).
- Install the new power steering pump and reconnect the lines.
- Refill the power steering fluid and bleed the system according to the vehicle’s manual.
Tools Required: Wrench set, fluid catch pan
Safety Warnings: Wear gloves to protect from fluid; ensure the battery is disconnected.

4. Inspect Wheel Bearings

Sub-steps:
- Raise the vehicle securely on jack stands and remove the wheel.
- Check for play in the wheel bearing by shaking the wheel side to side and up and down.
- If the bearing is worn, remove the brake caliper and rotor, then replace the wheel bearing using a bearing puller.
Tools Required: Jack and jack stands, bearing puller, socket set
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported.
