Q: Power steering problem

asked by on

When the truck is stopped there is a rattle and it continues when you start moving. The rattle becomes much worse when I turn the steering wheel in either direction and is accompanied with a hissing sound. I added some PS fluid and the sound still persists and there is now fluid on the engine as if it sprayed out. I dont know if its related or not but I replaced the Universal Joints in the one piece drive shaft about a week ago.

My car has 123500 miles.
My car has an automatic transmission.

Hello. From what you are explaining it sounds like your power steering pump is failing. I usually start by checking the tightness of the power steering belt. If the belt is fine then I check the pressure coming from the pump with a pressure gauge. Most of the time the pump is the issue. I have also seen restrictions in the steering gear box that will cause this also and that will require that the gear box be replaced.
