Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use wheel chocks for added safety.

2. Inspect and Replace Power Steering Fluid

Tools Required: Funnel, container for old fluid
Sub-steps:
1. Locate the power steering fluid reservoir.
2. Check the fluid level and color; if dark or below the minimum mark, proceed to replace.
3. Using a turkey baster or siphon, remove old fluid from the reservoir.
4. Refill with the manufacturer's recommended power steering fluid until it reaches the proper level.

3. Inspect and Replace Serpentine Belt

Tools Required: Socket set, belt tensioner tool
Sub-steps:
1. Locate the serpentine belt and inspect it for cracks, fraying, or glazing.
2. If damaged, relieve tension using the belt tensioner tool and remove the old belt.
3. Refer to the vehicle’s belt routing diagram to install the new belt.
4. Ensure proper tension is maintained on the new belt.

4. Inspect and Replace Wheel Bearings (if necessary)

Tools Required: Jack, jack stands, socket set, torque wrench
Sub-steps:
1. Lift the vehicle and remove the front wheel.
2. Check for play in the wheel bearing by grasping the wheel at the 12 and 6 o'clock positions and rocking it back and forth.
3. If there is excessive play, remove the brake assembly, hub, and bearing.
4. Replace the bearing with a new one and reassemble components, ensuring proper torque specifications.

5. Inspect Brake Components

Tools Required: Jack, jack stands, socket set
Sub-steps:
1. Remove the wheel and inspect the brake pads and rotors for wear.
2. Ensure that brake calipers are not sticking; lubricate sliding pins as necessary.
3. Replace any worn brake components to eliminate noise during turns.
