Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, and set the parking brake.
Disconnect the battery to ensure safety while working on the steering system.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, add the recommended power steering fluid until it reaches the proper level.
Inspect the fluid for contamination; if dirty, proceed to flush the system.

3. Inspect Power Steering Pump

Visually inspect the power steering pump for leaks or damage.
Start the vehicle and listen for any abnormal noises from the pump.
If the pump is faulty, remove it:
- Disconnect hoses from the pump.
- Remove mounting bolts using a socket set.
- Replace with a new pump and reconnect hoses.

4. Examine Steering Rack and Tie Rods

Lift the front of the vehicle using a jack and secure it with jack stands.
Inspect the steering rack for any signs of leaks or damage.
Check tie rods for play by moving the steering wheel back and forth; replace if any play is detected.

5. Check Drive Belt Condition

Inspect the drive belt for cracks or wear; if damaged, replace it.
Ensure the belt is properly tensioned; adjust as necessary using a torque wrench.

6. Final Assembly

Reassemble any components that were removed.
Reconnect the battery.
Lower the vehicle back to the ground.
