[Vwdiesel] 81 Rabbit - wheel bearings

[Rolf Pechukas]

shop just told me 'klunk' is wheel bearings in both rear wheels
pass side is much worse, but apparently driver's side is iffy too
they did not want to re-pack b/c they might be shot, and then 'big  
money'
what's the best move here?
order new bearings for both sides and install?
any online how-to procedural anywhere?
I'd like to know exactly what to expect b/c this will be a driveway  
operation at 10°f in 2' of snow
thanks all
