I have a power steering problem. It looks like fluid is returning into a reservoir making a bubbles and leaks under the cap and pump is making ugly noise before it has warmed up.

make sure power steering pump is full then try bleeding air by turning to lock one way and holding for thirty seconds then do the same in other direction. do this five times then check fluid and only use power steering fluid not transmission fluid. it may be the valve in pump making noise though.

It sounds like you have a power rack and pinion selector valve going out and it is blocking the flow of the fluid. This happens after the pump goes out because of the metal from the old pump gets stuck in the valve.

something like this I would say no due to it being the rack and not the pump if it was doing the same thing.

The "owners" of this site have chosen to screw the experts that are NOT volunteers by paying them $.50 per answer. They are operating out of Dana point in Ca. and that can't be cheap, but they are!

disregard what doc haggerty says . It probably is still the rack gone bad it's the part eh column connects to and goes to turn the car.
