In general BMW driveshaft's are of the two-piece design. This design is intended to completely eliminate natural frequency vibrations.  The problem with this design of universal joint is that repair is difficult, relatively expensive and prone to early failure.  And front driveshaft run out, the most common BMW driveshaft design is that the front driveline is centered directly off the transmission main shaft. This  design causes BMW driveshafts to rotate with the smallest amount of radial run-out possible. Additionally the rear part of a BMW driveshaft is centered with the next most accurate means, a precision piloted fit bmw.jpgflange.

As with and high speed rotating mechanism when parts wear or fail, serious vibrations can start small and build to cause sever damage to other drivetrain related components.  An updated designed universal joint is manufactured to exacting specifications, which specifically eliminates the root cause of early BMW u-joint/driveshaft failure. 

Our state of the art manufacturing and high speed balancing facility  provides driveshafts that exceed the original manufactures specifications.  Our shafts also come with a new center bearing.

Replacement of the old existing driveshaft can prevent future diveshaft problems and failure bushing and seal in transmissions and differential caused by excessive vibration.  Also enhancing the comfort of your BMW's ride.

Worn Flex Disc can also cause vibrations

Between the transmission output shaft and the driveshaft, there is a flexible coupler (Flex Disc) bmw_flex_disc.jpgthat joins the two together.  This rubber, reinforced coupler isolates vibration from the rest of the drivetrain, while transferring power from the engine and transmission to the rear differential and wheels.  As the flex disc ages, and is exposed to the elements, these discs can develop cracks and begin to disintegrate.  The rubber shell is reinforced with rope cords on the inside, and it is not uncommon to see one completely fall apart.  It is recommended that you inspect this rubber joint about every 10,000 miles or so (about once a year) to make sure that it still looks okay.  If it fails, it does have the potential to leave you stranded.

The basic function of your driveshaft is to transmit power from one point to another in a smooth and continuous action. In automobiles, the drivetrain is designed to send torque through an angle from the transmission to the rear axle. 

The driveshaft must operate through constantly changing relative angles between the transmission and axle. It must also be capable of changing length while transmitting torque. The axle of the vehicle is not attached directly to the frame, but rides suspended by springs in an irregular, floating motion. This means the driveshaft must be able to contact, expand and change operating angles, when going over bumps or depressions. This is accomplished through universal joints, which permit the driveline to operate at divergent angles, and slip joints, which permit contraction or expansion to take place.

We specialize in high speed balancing of the final assembled driveline's If your shaft drivelinestraight_large.jpgis not balanced with the actual end yoke and U-joints, you have not fixed the potential vibration problems. Our shop features the latest in driveling manufacturing and balancing equipment.

 

High Speed Balancing is the secret to smooth vibration free performance!

 

A driveshaft will not run smooth and vibration-free unless it is straight and in balance. Our shafts are, after assembly and before welding, pre-straighten to the above specifications. We then dynamically high speed balance the entire shaft assembly at the speed representative of the speed the shaft will encounter in its normal application.
