Solution

1. Preparation

Gather tools: socket set, torque wrench, stethoscope, fluid catch pan, and safety glasses.
Ensure the vehicle is parked on a level surface, and the engine is cool before starting work.

2. Inspect and Replace Drive Belts

Sub-steps:
1. Open the hood and locate the drive belts.
2. Check for signs of wear, fraying, or glazing on the belt surface.
3. If damaged, remove the old drive belt by loosening the tensioner pulley using a socket wrench.

3. Check and Top Off Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir.
2. Remove the cap and visually check the fluid level.
3. If low, top off with the recommended power steering fluid type.
4. Inspect for leaks in the hoses and connections; replace any faulty components.

4. Inspect and Repair Transmission or Differential

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Inspect the transmission and differential for leaks and any physical damage.
3. If leaks are found, replace the affected seals and gaskets.
4. Refill transmission or differential fluid as necessary, using the manufacturer-recommended fluid type.

5. Tire Inspection and Replacement

Sub-steps:
1. Remove the tires from the vehicle for a thorough inspection.
2. Check for uneven wear patterns or damage such as bulges or cuts.
3. Replace any damaged tires with new ones.
4. Ensure that all tires are properly inflated to the manufacturer’s specifications.
