Alrighty so here is the scoop. I installed an s475 kit about 3 weeks ago, and right from the start I noticed a vibration noise as the motor would stay on longer. I have been scratching my head since trying to figure out wha could be vibrating because everything I could see clears just fine. It was also weird that it would only occur after driving the truck for longer than 20-40 minutes. It makes my truck sound like a ford 
So there were no other symptoms other than the noise before I went on a road trip, and I then I noticed if I came to a stop while turning, my power steering and brakes were gone until I reved the motor up. Then I noticed that my power steering would make a growling noise if I tried to turn while not moving. There are no leaks, and I flushed my system less than 6000 miles ago and the fluid is already very dark brown.
Think it's a bad pump?
