  1. this is my first post:

    I bought my 94 LS 400 in Aug. 07, so i've only had it a few months. shortly after i bought it, it began making a faint whining noise. in my experience with cars, i know this to mean it's getting low on PS fluid, so I checked it. it was fine. very quickly, the noise began to get worse, so I took it to a shop to have them listen to it, and the mechanic told me that it had air in the pump. they also diagnosed a few other things for me, which they ended up being wrong about, so I decided to go elsewhere. I went to my a friend's mechanic, who told me that I needed a new pump. So i went to the parts store, bought a new one, put it on, no difference. i cleaned the solenoid filter, which was disgusting, and got the fluids back to where they should be, and still no difference. I will say, however, that i was amazed at the difference in how the steering responded after cleaning the filter. it's nearly effortless. but the whining is still there, what's the chances that i was sold a bad pump? does this happen often? i was told that it could be the rack & pinion. when the belt is off of the car, it doesn't make this noise. would the R&P still make this noise with the belt off? i'm baffled. thanks for your help, guys

    so i put another pump in the car yesterday... it still whines. funny thing was though, when i backed it down off the ramps, it stopped whining, for about 10 seconds. as soon as i touched the wheel again to turn it, it started up again, and hasn't stopped since. i've changed the pump twice, cleaned the filter, and turned the wheel lock to lock 35 times each way. i was told that this would bleed the system. i'm lost. i really have no idea what could be the problem. the steering is VERY smooth, especially since i've cleaned the filter. so this doesn't seem to be affecting the car's performance any, it's just a loud, obnoxious noise. and like i said, it's not something that comes and goes. it's constant. if the pump is not bolted down correctly, would it have anything to do with it?


  2. yes, harky, it was a reman from autozone, came with a warranty, so i think i'll be pulling it off and taking it back for a replacement. my uncle told me the same thing last night, that in 45 years of him being a mechanic, he can count on both hands how many bad pumps he's been sold that were reman. thanks for your help.
