My wife's Yaris is in early stage of wheel bearing failure. Its only a slight drone at the moment but jacking it up and spinning the wheels confirm that its the OSR bearing that's noisy. Its only done 33k but a quick google reveals that its not uncommon for them to go that early.
Anyway, my local independent who does most of our car servicing has quoted £202 inclusive. The same garage changed the front wheel bearing (including hub) on my Focus for £140 about six months ago.
Any idea why the Yaris would cost so much more?
