Took the LT in to Open Road BMW in Newmarket for its 20,000 km service and to get a leak from the boot on the final drive checked. When they were removing the sleeve to repair the pinion seal they stripped the 4 notches in the sleeve that allows the tool to pull the drive out of the sleeve, so now they can't get it out, the dealer has sent it out to an outsource repair service. Question to those in the know, can this repair be made or am I looking at a new final drive (as I heard one service advisor mention)? or should I be insisting on a new drive thinking how the procedure could be done in the future with the notches stripped? It's an 04 and its under warranty although it doesn't really matter as it was the dealer who damaged it.
