Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to ensure safety.

2. Inspect and Replace Serpentine Belt (if damaged)

Sub-steps:
- Locate the serpentine belt routing diagram (usually found on a sticker under the hood).
- Remove the belt tensioner using a socket to relieve tension on the belt.
- Slide the old belt off the pulleys.
- Inspect pulleys for wear; replace any that are damaged or misaligned.
- Install the new serpentine belt following the routing diagram.
- Reapply tension using the tensioner.

3. Check and Refill Power Steering Fluid (if low)

Sub-steps:
- Locate the power steering fluid reservoir (usually near the engine).
- Remove the cap and check the fluid level against the marked indicators.
- If low, add the manufacturer-recommended power steering fluid until the proper level is reached.
- Start the vehicle and turn the steering wheel to bleed excess air from the system.

4. Inspect and Replace Wheel Bearings (if faulty)

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheel to access the hub assembly.
- Check for play in the wheel bearing by wiggling the hub; if movement is detected, the bearing is likely worn.
- Remove the hub assembly and replace the wheel bearing using a bearing press tool.
- Reassemble the hub and wheel, ensuring proper torque specifications are followed.
