Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery before performing any electrical work.

2. Inspect and Replace Belts

Tools Required: Socket set, belt tension gauge
Sub-steps:
1. Remove the engine cover (if applicable) to access the serpentine belt.
2. Inspect the serpentine belt for cracks or wear.
3. If damaged, remove the belt by loosening the tensioner pulley.
4. Install the new belt, ensuring it follows the correct routing.
5. Re-check tension and secure the engine cover.

3. Check and Replace Transmission Fluid

Tools Required: Transmission fluid gauge, socket set
Sub-steps:
1. Locate the transmission dipstick or fill plug.
2. Remove the dipstick and check fluid level.
3. If low, add manufacturer-recommended transmission fluid until proper level is reached.
4. If fluid is dark or burnt, perform a fluid change by draining and refilling with new fluid.

4. Inspect Power Steering System

Tools Required: Power steering fluid, funnel
Sub-steps:
1. Check the power steering fluid reservoir for level; top up if low.
2. Inspect the power steering pump for leaks.
3. If whining persists, consider replacing the power steering pump.

5. Examine Differential

Tools Required: Differential fluid, wrench set
Sub-steps:
1. Check the differential fluid level via the fill plug.
2. If low, drain and replace with appropriate differential fluid.
3. Inspect for any signs of damage or leaks in the differential assembly.
