Hello-
Hoping someone can chime in and help me out of a jam. My wife's 94 6 cyl 4Runner was leaking power steering fluid badly so I decided to replace the power steering pump with a remanufactured unit from Advance Auto. Had issues getting the pulley off to remove the leaking unit so i sawed the bolt off that is behind the pulley and removed the old pump with the pulley attached. No problems but cost me a new pulley. That is background info.
I installed the new pump and pulley, had to tap the new pulley onto the shaft , installed the ATF, jacked the front of the vehicle up, turned the wheels to lock in both directions while maintaining correct level of fluid in the reservoir, lowered the vehicle, started the vehicle, tried turning the steering wheel and it was if I had manual steering. Nothing at all. Like the pump was not even installed.
So, i did notice that I forgot to install the small brass fitting that goes in the hole where the air valve goes into the pump. So I took the pump out and corrected that and reinstalled.
Also I notice that the amount of in-out play in the shaft was more than on the original pump about 1/8 inch more. Could the tapping of the new pulley on to the new pump have broken something inside of the new pump? I would not think this to be the case but I am no expert obviously.
Same result - nothing.
So - the next thing I did was remove the low pressure hose that returns the fluid to the reservoir, attached a piece of tubing into the end of it and stuck it in a empty windshield washer container to catch the fluid. I then put my thumb over the bottom of the metal tube part of the reservoir and had my wife start the vehicle and turn the wheel right to left.
I was expecting a pretty decent amount of fluid to come out of that hose and I has a bootle of ATF opened and on hand to keep the reservoir topped off as the fluid come out of the tube going into the empty washer bottle. However, all that came out of there was little dribbles of fluid and an occasional burst of fluid.
So that is where I am currently at.
I am looking for some insight as to if the fact that a intermittent stream of piss came out of that hose indicates that
1- The remanufactured pump was DOA and another one would correct the issue
2 - There is air in the system that is causing this issue and once it is out the problem should be gone.
3 - there is something else that I am missing.
I will also mention that I never heard any whine or growl from the new pump
Also I was wondering if pinching the return line to the reservoir should cause the pump to whine if it is in fact working correctly.
Any help would be greatly appreciated as my marriage may suffer sever stress if I dont get this figured out soon:sing:
I have tried my best to describe my dilemma with the most detail that I could
Regards,
KF
