hi all, the bimmer started whining the other night after a long run home, i suspected either belt tensioner or alternator bearings, after using my trusty steel rod to listen.This morning i performed exploratory surgery and found the problem, a worn front/nose bearing in the alternator.now, are there any places i can get this repaired, or should i just go for a s/hand unit? and, ah-em, does anyone have one laying around?...i need to get this sorted, wify been forced to use the family p$%£&n s"&athanks
