Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect Power Steering Fluid

Remove the power steering fluid reservoir cap.
Check the fluid level; it should be between the minimum and maximum marks.
If low, top up with the manufacturer-recommended power steering fluid.

3. Check for Leaks

Visually inspect the power steering lines, pump, and rack for signs of fluid leaks.
Clean any spilled fluid and monitor areas for new leaks after operating the vehicle.

4. Test Power Steering Pump

Reconnect the battery and start the engine.
Turn the steering wheel from lock to lock while observing the pump.
If it makes excessive noise or the fluid foams, the pump may need replacement.

5. Inspect Steering Rack

Lift the vehicle using a jack and secure it with jack stands.
Inspect the steering rack for physical damage or excessive play.
If found defective, it will require replacement.

6. Replace Serpentine Belt (if necessary)

If the serpentine belt is worn or slipping, remove it using a socket set.
Install a new belt according to manufacturer specifications, ensuring proper routing.
Torque any tensioner bolts to the specified values.
