Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal.

2. Inspect and Replace Power Steering Fluid

Tools Required: Socket set, fluid pump, funnel
Remove the power steering fluid reservoir cap.
Using a fluid pump, extract old power steering fluid and dispose of it properly.
Refill the reservoir with the manufacturer-recommended power steering fluid.
Replace the cap securely.

3. Replace Serpentine Belt (if necessary)

Tools Required: Socket set, belt tensioner tool
Locate the belt tensioner and relieve tension to remove the serpentine belt.
Inspect the belt for cracks, fraying, or glazing.
If damaged, install a new serpentine belt by routing it according to the belt diagram.
Ensure proper tension is applied, allowing for slight give when pressed.

4. Inspect and Replace Wheel Bearings (if needed)

Tools Required: Jack, jack stands, socket set, bearing puller
Lift the vehicle and secure it on jack stands.
Remove the wheel and brake components to access the wheel bearing.
Inspect the bearing for signs of wear or damage; replace if necessary.
Reassemble the components in reverse order, ensuring proper torque specifications are met.

5. Check Differential Fluid (if applicable)

Tools Required: Socket set, fluid pump
Locate the differential and remove the fill plug.
Check the fluid level; if low, drain and refill with the appropriate differential fluid.
Inspect the fluid for metal particles or a burned smell, indicating internal damage.
