Hey folks

I suddently got this whining sound from front of the engine. i cant locate it exsactly but it sounds almost like theres not enough oil in the power steering. But there is plenty and the sounds doesnt come from the pump.

it follows the rpms.

yesterday i tried to take of the belt and started up the engine. the sound was gone.

could this be the waterpump on its way out? :-/

could be that transmission pump. drop trans pan and clean the strainer and everything in the pan. refill with Toyota T4 fluid and it should go away.

No it's not the water pump. The WP is inside driven by the timing belt so when you took your serpentine belt off the WP was still spinning. At least you narrowed it down to something spinning with the serp. belt. Maybe the PS pump is starting to go or it could be a bearing in one of the many pulleys that the belt spins. If you still have the belt off try spinning and wobbling all the pulleys to see if any make noise.

I noticed this very recently on my 92 as well. I think it is something to do with the PS system. Mine varies with the rpm as well. Additionally, when I'm turning in to a parking spot while making a low speed (under 5 mph) 90 degree turn, there is a labored sound the more I turn the steering wheel. I haven't had a chance to get mine checked out yet, but it's definitely a concern for me right now. Please keep us posted as to what you find.

i had the same issue as u guys, started it up and whined like mad. another member said it was the Trans pump and i did what i typed out in post 2 and the noise went away.

Licelsior, i took of the serpentine belt and the sound disappeared, so it could'nt be the trans pump then right?

I can exactly say where the sound is coming from. Dont know if its the ps pump.

But i bought a rebuild power steering rack a week ago so maybe it has something to do with that. I also think i can feel a bit humming feeling in the steering while turning. I dont think the power steering operates 100% the same way as before but its hard to explain.

I filled with some swiss power steering fluid. should be great quality and is says Toyota T-IV comparible on the bottle so should be no problem?

lexus recomend to use transmission fluid dextron II or III for power steering

just suggest u using Toyota T4 fluid for the PS and trans. maybe it could be a bad pulley like dean said. i know my fan bracket pooped out and made a slight squeaking sound.

Your fan bracket pooped out? what you mean and what did you do about it?

LiCelsior

The whole fan or is there a bracket or how is it? Can i disconnect the fan so see if the sound dissapears before i go buy all kind of things. its hard to get used parts around here. (Denmark)

if u look at ur fan clutch, the fan bracket is behind it. its a little annoying to remove it since u have remove the timing covers and etc.

take a video of it and try to get a mechanics stethoscope to listen to it.

T-IV for the trans= yes
T-IV for the PS= NO

Power steering needs "normal" dexron/mercon spec transmission fluid.

Hmm okay so that might be the problem. I thought the transmission and power steering fluid was the same :-/

I'm gonna flush the power steering and fill with dexron III instead. Hope that works.

Does putting type IV into the PS instead of using type III really cause a whining noise? or is there even a big difference between using one or the other in the PS?
