So, the one thing holding me back from my DSM being on the road is the PS system not working.
I've replaced mostly everything associated with it: Rebuilt PS Pump and rebuilt rack and pinion, tie rod ends, other linkage, and a singular PS line (since the others were fairly inaccessible)
And even after replacing all of those components, it still does not function.
Here is what happens:
After bleeding the system, the power steering works for about 15-30 seconds. In fact, there is so much pressure in the system that one of the power steering lines torques under the pressure and my RPM's drop by about 1-300 when the wheel is maxed out in either direction. After cycling the wheel some, the system stops making pressure and the line stops torqueing. On test drives, the PS sometimes starts working again, but very intermittently and only for 1-2 seconds.
Here is the post my dad made on facebook asking for advice:
My son and I replaced a leaky rack & pinion. Power steering worked for about a minute, then stopped working. We then replaced the power steering pump and the high pressure hose. Again, it worked for about a minute then stopped. Here is what we did - replaced rack - with the front lifted on jacks, and the motor off, we turned the wheels lock to lock to bleed all bubbles out - when the reservoir stopped bubbling, we cranked the engine and bled again - power steering worked but then stopped - removed the return line and ran it into a bucket and flushed the entire system into a bucket - started over by rebleeding the system with engine off and then running - power steering worked and then stopped after about a minute. At this point we are stuck. Any constructive input would be greatly appreciated.
Some of the comments from facebook said we might have gotten a bad rack, or maybe the bypass valve for the system was stuck open. Personally, I have no clue. I figured tuners answers would probably be better than facebook so I'm posting it here as well.
