I've been lurking long enough to know there are some very knowledgable people here. Maybe you guys can help me with a power steering pump problem on my 87 4runner 22re. I'm getting ATF everywhere, but I guess that's OK 'cause the the truck has the "blood bath" interior to match!
So I just moved to NC from flat FL and was looking forward to doing a little more wheeling when my power steering pump took a dump. I got a remanufactured one and also took advantage of the opportunity to replace the noisy tensioner/idler bearing. I followed the instructions in the factory service manual for bleeding after hooking it all up. power steering worked great - really quiet, too!
Then I noticed a puddle of ATF forming under the truck. Turns out the reman pump was p!ssing fluid from the area of the flow control valve. I swapped the pump for another one. Hooked it up, filled it up and bled it. No foaming. No bubbles. No whining. No leaking.
And no friggin power steering at idle! Works great when I got it revved up above 1000 rpm, though. Parts store insists there is air in the pump, so I repeat the messy routine in the manual to get the air out and bleed it again. Same result. No power steering at idle!
Maybe they used the wrong flow control valve? I don't think there is air in there and I am getting tired of (but pretty good at) swapping pumps.
