Drivetrain Guibo
A common wear item on BMWs over a period of time is the drivetrain guibo. The guibo serves as an interface between the transmission and the driveshaft. Since the guibo is primarily made from rubber, it acts as a damper when shifting and engaging into gears, so that the transfer of power to the driveshaft is smooth and dampened, instead of abrupt and harsh.
Replacement of the guibo depends on age and driving style. We have seen vehicles less than 12 months old with 15,000 miles that had already started developing cracks around the bolt holes. We have also seen vehicles over 5 years old and over 100,000 miles with guibos without any stress cracks whatsoever. Needless to say, if you drive your car aggressively, your guibo may have to be replaced sooner than others.
