Root cause of RH rear wheel bearing ceasing.

[lv619]

Currently have my car in at the mechanics to get the clutch cable fixed and he has informed me that my RH rear wheel bearing is buggered. Now I am not getting this fixed for the time being until I know exactly what is causing the issue as this is about the 3rd time it has happened in as many years, the latest about 6 months ago (probably only 5000km ago, as I FIFO for work and dont drive it that much). I told the mechanic to have a thorough inspection to find the issue, however i suspect he will just tell me that the whole rear assy needs rebuilding.
