Solution

1. Preparation

Gather tools and ensure the vehicle is on a level surface.
Safety equipment: gloves and safety goggles.

2. Inspect Serpentine Belt

Tools Required: Flashlight, belt tension gauge.
Inspect the serpentine belt for cracks, fraying, or glazing.
If damaged, replace the serpentine belt:
1. Loosen the tensioner pulley using the appropriate socket.
2. Remove the old belt.
3. Route the new belt according to the belt routing diagram.
4. Tighten the tensioner and ensure the belt is seated correctly.

3. Check Power Steering Fluid

Tools Required: Clean rag, funnel.
Locate the power steering fluid reservoir.
Check the fluid level; if low, top off with the recommended fluid.
If fluid is contaminated, flush the system and refill.

4. Inspect Power Steering Pump

Tools Required: Wrench set, torque wrench.
Check for leaks around the power steering pump.
If the pump is noisy or leaking, replace it:
1. Disconnect the battery.
2. Remove the serpentine belt.
3. Disconnect power steering lines and electrical connections.
4. Unbolt the pump from its mounting.
5. Install the new pump and reconnect all components.

5. Check Transmission Fluid

Tools Required: Transmission fluid dipstick or funnel.
Check the transmission fluid level; add if necessary.
If the fluid is dark or burnt-smelling, perform a transmission fluid change.

6. Inspect Wheel Bearings

Tools Required: Jack stands, socket set.
Lift the vehicle and check for play in the wheel bearings by shaking the wheel.
If play is present, replace the wheel bearings:
1. Remove the wheel and brake caliper.
2. Take off the hub assembly to access the bearings.
3. Replace with new bearings and reassemble.
