Anyone ever have a power steering pump start knocking? I replaced my power steering pump last year and it burned out so I took it back and got a new one. I put it in 2 days ago started my xj up and heard a horrible knocking sound. I thought it was my engine ( freaked me out) but it seemed to come from the pump. It has a new pully on it and I was wondering if this has happened to anyone else? What's a good way to make sure its the pump?

 

Make sure there is no air trapped in the system...turn the wheels from lock to lock lightly contacting the stops several times to bleed air out of the system. Check the fluid level and add if necessary.

 

I already have done this a few times. I don't believe there is anymore air in the lines. Any other ideas? And anyone ever hear it knock before?
