I had some issues with the power steering pump and box in Moab. The original one I put in the truck when I built it went out, the first replacement I installed in Moab went out after only a few miles and the 2nd replacement worked, but whined really bad (I also plumbed in a cheap cooler and filter when I installed the 2nd pump). On one of the trails I hit a big rock hard enough with the passenger tire to blow out one of the seals on the steering box, so that was leaking pretty bad as well.
I decided the proper fix was a system with at least twice as much fluid capacity and a better cooler along with another stock replacement pump and steering box. I ordered up some parts from PSC and picked up a replacement box, pump, fittings and hose locally. The reservoir also has a built in filter to help keep the fluid clean.
I installed the remote reservoir can on the stock pump using a -6 AN adapter for the high pressure line.
I added some tabs to bolt the cooler on in front of the condenser.
Finally I added some brackets to mount the new reservoir off of the drivers side shock hoop and plumbed everything up.
I used a vacuum pump to bleed the system, the capacity went from the 1qt stock capacity to 2.5 quarts. There was no foaming or noise from the pump after starting it up. I took it on a test run and already I've realized that the new pump has issues too. It appears that the pressure valve is set too soft as I have difficulty steering when driving slow on asphalt or when I'm in four wheel drive and have traction offroad. :cussing:
I'm hoping I can just swap out the valve from the back, but it may require a whole pump swap again. This time I think I'll have a local shop rebuild it instead of getting the crap Chinese reman pumps from Autozone...
