Just 2 days after successfully work out one issue, another rears its ugly head. 1997 Ram 2500 V8 5.9.

So yesterday, I noticed the pitman arm shaft seal was leaking a bit. So I went out and got some Lucas Oil powersteering stop leak as I didnt think the leak was bad enough to need seal replacement, and Im usually a pretty good judge of that.

So I topped off the fluid with the stop leak with the engine still warm, and I checked it with the "HOT" markings on the dipstick. It was right on the money full. It didnt take much to get it back to full.

Heres where I think something went wrong. The engine was warm, but not hot. Thats why the fluid level looked to be just short. When I checked it today, with engine actually hot, the level was overfilled. Not just overfilled, quite overfilled.

This morning, before I checked, it started right up with no noises or strange problems. I drove it about 20 miles before I had to step out with the truck idling, then I noticed the noise. It was not audible from the cab with the radio and heat going.

So, what, did I kill the pump or something? What else could this noise be? Its not an engine knock, its too...prominent to be that. Engine oil is fine. This is definitely a noise from something just outside the engine block.

Check it out. Ram WTF: http://youtu.be/0r5opUptc1k

EDIT: The click gets faster and slower with engine speed, however, volume remains the same. No loss in power steering, engine power, etc.

I have never heard a P/S pump make that kind of noise. It almost sounds like just something hitting something on the belt/pulley/fan etc.
Does the noise change at all with steering input?

Dial up speed or less. I will try it and see if I can get it to work.

After watching some YouTube vids, I agree. Power steering makes whines, not knocks.

I found it I think. It looks like the idler pulley between the AC Compressor and the Belt tensioner. It has a TON of play in it. Even with the belt on it. Will check and report. I made this thread half out of panic.

Yeah, I got really nervous, it sounded pretty bad. The problem revealed itself pretty immediately though through watching. Check out the bearing in the pulley! Toast. Nice and quiet now. Thanks all.

Nice job. It sounds pretty terrible in the video.
