still got to pull the gearbox out to replace the bearings, not a "hard" job for a mechanic, but a bit of a time consuming one... starter motor off, wires off, tailshaft off, gearbox out. replace items, then put all back in... wouldnt even take a day for a mechanic. might cost you a few hundred though, as the others have said, replace your clutch when you drop the gearbox out... saves paying someone twice to do the same job (pulling theb ox out to do bearings then pull it out again to do clutch)
i know its annoying cause i have that same problem lol. but my clutch is new. but i wasnt able to source a bearing at the time i did my clutch, and now im paying for it with having to pull it all out again... :@ grr...
