    PSC Hydro Assist install

    I am about 3 weeks post the PSC Hydro Assist install and I must say it is awesome.. Install sucked a good bit, but once we figured out all the differences between the instructions and my JL as well as the bleeding of the system, it has been great. Did the entire set up, new pump, steering box, ram, cooler, etc. The instructions were super detailed which was great, just had some differences between the JL they used and my JL. Biggest issue we had was bleeding the system and destroying the belt which destroyed all the pulleys..

    Based on their directions the bleeding of the system was going to suck, and they were spot on.. it sucked. We ended up having to get a bigger belt than what they sent out and recommended. Calls for 90" belt but we ended up using a 91". The 90 was so tight that it literally melted the upper pulley, started to on the second pulley, and caused issues on the lower pulley.

    Had the PSC installed while doing the UD60 swap so we had to do some figuring out with the pitman arm as the UD60's use JK steering components, but the pitman arm needed the JL TRE. Overall I am quite happy with the kit with both on and off road handling.

    How was your steering before the move to PSC? I've been fighting steering issues in mine for a while and have been talking to PSC about a kit. Any issues with disabling the electric pump?

    It was ok. Wasnít a fan off road with it. It would barely move if move at all my 37ís when running 6-8psi, so I knew it wouldnít be good with the 40ís at all. I know I wanted a complete kit and ditch the electric steering. Using the Tazer to disable the electric pump and a ton of other things when I switched over the axles.

    Mine also melted the pulleys. Switching belts fixed it for you?

    Yes. Went with a 91" belt vs the 90 they sent. I had even tried a different 90" to make sure the one I got wasn't the wrong size by accident.

    Interesting. I installed the kit last week and the 90Ē belt that came with the kit seems fine in my setup. Maybe Iím lucky or destined for failure. I know you had the first PSC JL kit so maybe some changes were made??

    My bleed also went much smoother than what Iíve heard from others. I did loosen the return line on top of the cooler when I filled to let air escape from a high point, but other than that I followed PSC instructions and spent an hour or so but it hasnít taken any more fluid in the last 2 days and the pump isnít cavitating.

    Iím still on 37s so I didnít install the ram yet, but the difference in the PSC setup vs my stock steering is AMAZING! Best mod yet. The shimmy and shakes are gone, steering is tight, it tracks straight on the highway, and it has plenty of power to turn the 37s.

    I talked to Tom about the belt size issue I had and he said he had heard of like 1 other that way. It could be some random variance, a messed up factory tensioner, whatever. My kit was also like 1 version post the prototype and they have since then redesigned a good bit of stuff. Just as a disclaimer.
