re. Wheel bearing question

[Denis]

  I m agree.

   He should call the bearing dealer to be sure if both bearing is identical or diff. When i went to buy mine i have been told some years 90Q has same front and rear.

    I know that the wheel bearings for the 4000 quattro's are different diamter and thickness for front and rear - I would expect the M80's to be different too.

     A virbration or occillation could be caused by a number of things, starting with wheel/tire out of round, runout or imbalance.  Loose bushings or tie-rod ends may contribute to viration - play will be noted when wheel lifted off the ground and some serious force applied. YES sure.

    A bad wheel bearing typically does not cause vibration(
    Noise = Vibrations. Technically impossible to make sounds without vibrations..... i know i cut the hair in 4 but i wanted to comment :-)
    ), but more of a noise similar to that of a propeller airplane,  increasing in volume with speed and worsening progressively as the bearing goes south. yes

    Greetings,

    My mechanic told me that I had a bad bearing on my '89 80 Quattro.  It 
    sounded like the rear ones to him, so I order one.  In the interim, he had a 
    motorcycle accident and another guy at the shop pulls the wheels and 
    determined that it's the front one.  He puts the rear bearing that I ordered 
    on the front.  Is this acceptable?  Or is the wheel vibration that I hear 
    and feel above 65 attributed to the switch?  Or, is the vibration due to the 
    fact that i'd recently had the wheels aligned prior to the bearings being 
    put on and need to get it aligned again?

    Thanks,

    Thomas Alexander
