When I had my bearings replace I got everything done.. can't remember the price (I think about $500 for both sides including mates rates bearings.)
Anyways. For a week or so afterwards there was a very slight oil leak out of both ends. Anyway, leak stopped for a bit and then when I'd stopped checking it it started again. Anyways. Long story short, oil seals had finally died (possibly replacement job pushed them over the edge) and the leaking oil screwed my pads up... bye bye mintex...
My advice, if you're getting the rear axle bearings replaced, get them to do your seals too... Probably need to be done, and saves on double labour by doing them at a later date...
