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.
The original center support bearing carrier from the factory employs a thin layer of rubber to secure the driveshaft, minimizing movement to reduce noise and vibrations in the vehicle's cabin. However, this design struggles to maintain the bearing's alignment under load, leading to gradual sagging and misalignment of the driveshaft. This, in turn, results in play during gear shifts and throttle application. Even in well-maintained vehicles, the initial rubber bushing can deteriorate and turn brittle, often developing cracks within 5-10 years. When this deterioration occurs, it can lead to heightened vibrations, clunking noises, and increased stress on the bearing. Additionally, replacing the stock carrier is a challenging task because it is permanently connected to the center support bearing, necessitating specialized tools for replacement.
