Solution

1. Preparation

Gather tools and safety gear.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace the Serpentine Belt

Sub-steps:
1. Locate the serpentine belt routing diagram (usually found on a sticker in the engine bay).
2. Use a socket wrench to relieve tension on the serpentine belt tensioner.
3. Remove the old belt from all pulleys.
4. Inspect the belt tensioner and pulleys for wear; replace if necessary.
5. Install the new serpentine belt according to the routing diagram.
6. Reapply tension using the tensioner and ensure proper alignment.

3. Inspect and Replace Wheel Bearings

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel and inspect the bearing for play by shaking it side to side.
3. If play is detected, remove the brake caliper and rotor.
4. Use a hub puller to remove the hub assembly.
5. Replace the wheel bearing using a press, ensuring it is seated properly.
6. Reassemble all components in reverse order and torque to specifications.

4. Check Power Steering System

Sub-steps:
1. Inspect the power steering fluid reservoir; top off or replace fluid if low.
2. Look for leaks in the power steering lines and connections.
3. If the fluid is contaminated, flush the power steering system and refill with the appropriate fluid.
