soo i get this weird humming noise when i push the throttle about 1/6 of the way most noticible in 6th gear anyone have any ideas?

also i know that the previous owner replaced the diff seal and diff oil but i also thought maybe the wheel bearingcould be a problem....any help would be great

thanks, Dan

 

lol, I JUST had the same problem with my car... It actually went away on its own. I have no idea what it was... It was in the passenger's side rear wheel. Sorry I cant be of more help.

 

The best Way to tell if its a wheel bearing is to jack your car up wheels off the ground and try to move the tire left and right ! placing your hands at 9 and 3 oclock you should not have any play if you do its a wheel bearing ! given the symptoms that you have provided this is likely the case !

 

the faster you go the louder the noise ( that's a wheel bearing )

 

no not the faster just when i brely touch the throttle
but when i hit it harder the noise isnt there

 

If your bearings are bad it will get louder with speed and not just RPMs. It sounds like driving over a rumble strip constantly while on the highway. Try to change revs in your car while parked to see if it's an actually anengine problem.
By ther way, what is the deal with these Audi wheel bearings? Luckily my dealer replaced my rear bearings for free when they went bad in my S4 in less than a week. I had a 1998.5 A4 2.8Quattro have its rear bearings go out on me too.

 

yep, I had the same problem hyper. Mine actually came back, and it is speed related, but mine only does it when its under engine braking ... It almost sounds like a stick stuck in the wheel, hititn the spokes, but Ive checked out everything under there and cant see anything wrong...
