Power steering not working?

My guess is that if you look clese enough you'll find a boot that is split and spinning the grease out. Just debris kicking up while driving is probably where the grit is coming from.

Maybe the problem is the rack and pinion and not the power steering pump? Usually when you replace the power steering pump, the info says to flush the system, get the old fluid out of it. In the past I have taken return line loose from the pump, aim the return line into container, rotate the pump pulley by hand to circulate the old fluid out. When the fluid runs clear, the old fluid is gone. I guess the new fluid is clear and not colored? That will also show you that there is circulation. If no circulation, maybe power steering hoses have a problem? I haven't looked up your power steering pump operation. If the info I posted isn't applicable, I'll find more info.

Just to add, you have to keep adding fluid when you flush it. The hi pressure hose is usually a threaded fitting, the return line is usually low pressure and uses a hose clamp.

What engine do you have. What liter

There is a speed sensor located in the steering column or the rear of the pump that has gone bad, this sensor tells the steering system how much pressure to release at a particular speed. Please check it out and get back to us so it can help others

Its on the passenger side by the fire wall down deep into the engine bay. Right side of the engine towards the front of the engine

It does sounds like it could be the rack but I have seen where the steering wheel angle sensor goes out and causes the same thing. To test the pump you need a flow test

Here is the location, its not to easy to replace but it fixed the last car we had in the shop.

Check out the diagrams (Below)

Please let us know what you find.

Cheers

If the dealership told you that replacing the pump would fix your steering problem then I would take it back there and make them fix it for no additional charge. Changing a rack and pinon takes different amounts of time depending on your rack set up.

The flow pressure test will see if the pump is good and if its good and the sensor is good you have a bad rack

Your welcome thats what were here for.
