vibration at idle in brake pedal and steering wheel

[hammerstroker]

i have a 00 f-350 psd dually. at idle the brake pedal and steering wheel vibrate and when i take off it goes away or when im in park rev it alittle and it goes away. its a really annoying sound. anyone help?

power steering fluid?

its full thats the first thing i checked could the pump be takin a crap?

Could be the pump or the hydro-boost. Also, once I had one in the shop with similar issues, and it had a cracked p/s cap. $6.00 fix!

now its while im driving like 5mph. but i can only feel it through the steering wheel. its like a buzzing/rattle noise it also does it while at park so i know its not in the drivetrain.

I am having a similar problem. I can't hear it, but my brake pedal feels like someone is holding a palm sander on it. It doesn't do it all the time either, maybe 50% of the time. I tend to think it's the hydroboost going out, but not sure. If you figure it out please let us know.

Ha! I just turned 154,000 too! I also forgot to mention that when I feel this vibration my brake pedal becomes noticeably mushy.

we are guessin its my powersteering pump. now its only makin noise when i turn the wheel or hit the brakes. some im buyin one and i will let ya know what the turnout is.
