I have an 03 KJ 3.7 project I just replaced the engine and a leaky power steering pressure side hose. The pump and hose were disconnected and sitting in the garage for a couple of months while I messed with the engine. When I put everything back together, I tried to burp the power steering and I can't get the air out. I put the front end up and turned the wheel (per the Jeep manual). I also used a vacuum pump. The fluid level doesn't drop and there are no leaks, but there are always more bubbles. And there is no power assist. I also pressure tested the system with a hand pump. No leaks found. I could replace the pump with a reman unit, or I could replace the reservoir o-ring and the return line. The return line on the original is integral to the cooler, but that assembly is pricey. Can I just cut the hose crimps and replace the hoses? Any suggestions would be helpful particularly in diagnosis before I start throwing parts at it.
