I recently had the power steering housing (? wherever you actually pour the fluid in) rebuilt because it was leaking and now its doing something funny. Basically when i first start it up, theres a loud almost whining noise from up front and it gets worse if i push on the brake or turn the wheel. After that it works pretty well. Today i left it running (it was making the noise still) and went and opened the cap off the ps and the fluid had a bunch of little bubbles in it...its not supposed to right? any ideas on the problem?

second thing is my oil pressure. I had an oil leak which i figured out was coming from the oil cooler so i fixed that but now my oil pressure's being really weird. It acts normal sometimes but other times it sits really low while i accelerate and as soon as i let off it starts to move back up into the normal range. again, any ideas on this?

any help would be good

the bubbles means there is air in the system turn the wheel back and forth many times add fluid as needed.. your oil pressure seems normal. my 90 4runner did it..

thanks i'll try that. any ideas on the oil pressure? i know the gauges aren't exactly the best thing to go by, but still...

Jack the front tires off the ground and without cranking the engine turn the wheels back and forth to get the air out and add fluid if needed.

Traben,
Just to be sure....your running ATF in the power steering unit right ?

If not that could also cause the bad sounds.

The OEM oil pressure gage is finicky at best...but this is the general range of its "normal" functionality.

Oil Pressure Guage
The OEM cluster gauge is not very accurate and it the FSM shows the following picture: (look in the thread below for the picture under "oil pressure")
