BMW Driveshafts for BMW E34 M5 S38 3.5L

Got a vibration through the driveline on your BMW? Did you know that the u-joints are not replaceable on a factory driveshaft? Our remanufactured driveshafts allow for future replacement of u-joints and are rebuilt to a higher specification than the factory driveshaft. We start with OEM u-joints and then machine yokes onto the driveshaft to allow for future u-joint replacement. All bushings, universal joints, center bearings are replaced with new hardware (flex discs are not included but available separately). The whole unit is then dynamically balanced on a precision Axiline Balancer.

This Bav Auto replacement flex disc (aka: the guibo) is a vibration dampener mounted on the back of the transmission which connects to the driveshaft. When it has worn, it can produce knocking sounds and a terrible vibration throughout the car. It's especially noticeable at low speeds and when starting from a standstill. Oil leaking from the back of the transmission will significantly reduce its life. This can also be used as an upgrade on the E30 M3. It has much more rubber in between the bolt holes which makes it last longer. This is 5mm thicker than the stock E30 flex disc so adjustment of the 2-piece driveshaft may be required. The original flex disc bolts can be re-used.
