Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Serpentine Belt

Sub-steps:
1. Remove the engine cover if necessary.
2. Locate the serpentine belt routing diagram (usually on a sticker in the engine bay).
3. Using a wrench, relieve tension on the serpentine belt tensioner.
4. Remove the old belt from all pulleys.
5. Install the new serpentine belt according to the routing diagram.
6. Re-tension the belt and ensure it is properly aligned on all pulleys.

3. Check and Top Off Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir.
2. Remove the cap and check fluid level against the markings.
3. If low, add the recommended power steering fluid until it reaches the proper level.
4. Start the engine and turn the steering wheel from lock to lock to circulate the fluid.

4. Inspect and Change Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or filler plug.
2. Remove the dipstick and check fluid level and condition (should be a reddish color).
3. If fluid is low or dark, drain the transmission fluid using a fluid pump.
4. Replace with the manufacturer-recommended transmission fluid.
5. Recheck the level after running the engine for a few minutes.

5. Inspect Wheel Bearings and Differential

Sub-steps:
1. Raise the vehicle using jacks and secure it with jack stands.
2. Spin each wheel by hand to listen for any grinding or abnormal noises.
3. Check for play in the wheel bearings by grabbing the wheel at 12 and 6 o'clock positions and shaking it.
4. If any bearings are worn, replace them according to the manufacturer’s guidelines.
