Hey guys I have a problem I recently ran in to. I recently replaced my power steering gear box on my 96 Cherokee due to bad seals in the old one, after I replaced it I bled the system properly doing the whole wheels off the ground, turning lock to lock 15-20 times ignition on and off, watching for bubbles and topping off power steering fluid. When my jeep is on the ground my wheels dont turn even with the ignition running it's very stiff to turn my wheel when reversing/driving and makes a grinding sound sometimes turning left and right about 1 1/2 turn. I replaced the seals in my previous gear box but they just kept blowing out from the pitman arm, after about 5 times redoing the seals I replaced the whole gear box. It seems like I'm not getting any power steering at all, my fluid is topped off, no whining while turning, just really hard to turn while driving and can't turn the wheel at all when sitting still. Sorry to the long post but any solutions to my problem guys? Thanks!
