    if you want peace of mind and can afford to replace the lot then do it

    are you sure its a wheel bearing and not tyre noise?

    You can normally tell if its tyre noise or wheel bearing, does the noise change when you steer when driving? Steppped tread can make wheel bearing type noise, If you run your hand along the tread it should be fairly even , if not can cause noise similar to a wheel bearing.

    get it on a jack and spin the wheel.. you will know straight away if its the bearing or not, i've had to do mine ( i think it depends on how you drive ) i've bought a premium one (68 pound each) from andrew page, put them on and one was faulty... so the job had to be done again but at least ive learned how to do it myself ( using my friends hydraulic press)

    Just had my nearside one replaced, on 150k so can't complain, my previous B6 Avant one went at 160k so seems about typical, 215k is very good

    My old FWD needed the front bearings done at ~150k.

    The quattro had a rear done before i baught it (~90k) which failed in relatively short order (fitters had damaged the seal!), the other rear became noisey and after replacing both of them i realised one of the fronts had started making a racket too, i ended up changing all four by 120k.

    On some cars the 'wiggling a jacked wheel' doesnt always tell of a wheel bearing failure. The most obvious is the 'whump whump' noise from a wheel when on a long steady turn, such as a motorway turn off.

    also this might help; when my bearing was worn, the noise was getting quiter when breaking.. but when i lifted the car up and span the wheel there was a clicking noise so i knew it was the bearing.
