throw out bearing??

my truck has reccently started to make a rubbing noise and vibration when its warmed up. the sound stops when im starting out in 1st gear but once my clutch is half way out it starts again but when im sitting still and the truck is idleing i can trurn the steering wheel to the right and the sound goes away but once i release pressure from the steering wheel the sound comes back i just replaced the power steering pump a day ago so i dont think its that anymore

thank you

oh and while driving at a constant speed i can hear it and feel it but when im accelerateing it goes away

I Have the same Problem on my 97 f350. I believe it to be the gears in the transmission it self. If you have a single mass flywheel then it will be more noticable. Inspect your tranny fluid if burned or metal ridden then there's your problem. Drain it and put new mercon 5 in and some ER friction modifier. May help a little, or atleast help prolong tranny life.. Also I have been told slightly over filling the tranny can help. other than that you are where I am....pressure plate is another possible culprit, but I'm conviced my zf5 is just about done.
