Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Tools Required: Jack stands, socket set, fluid pump, mechanic's stethoscope.

2. Check Power Steering System

Sub-steps:
1. Locate the power steering reservoir.
2. Inspect the fluid level; if low, fill with the manufacturer-recommended fluid.
3. Check for leaks in the power steering lines and hoses. Replace any damaged components.

3. Inspect Serpentine Belt and Pulleys

Sub-steps:
1. Remove the engine cover if necessary for access.
2. Visually inspect the serpentine belt for cracks, fraying, or excessive wear.
3. Use a belt tension gauge to check the tension; if tension is low, replace the belt.
4. Inspect the pulleys for wear and replace any that are damaged.

4. Check Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Check fluid level and condition; if low or burnt, drain and refill with the appropriate transmission fluid.
3. If necessary, perform a transmission service including filter replacement.

5. Inspect Differential Fluid

Sub-steps:
1. Locate the differential cover and remove the fill plug.
2. Check fluid level; if low, refill with manufacturer-recommended gear oil.
3. Inspect for metal shavings or debris in the fluid; if present, consider a differential rebuild.
