Better BMW Driveshafts

The biggest problem with BMW driveshafts, as you may already know, is that the U-joints from the factory are not replaceable. Typically when your U-joints "go out," you have to order a whole new driveshaft from BMW, which can cost thousands. Or you might find a driveshaft repair shop that will rip out the old joints and reinstall them the same way BMW does it, which puts you right back to square one. Even worse, some shops will simply weld them in, giving them no chance whatsoever at life again. 

We developed a better way to do it.

Every driveshaft that comes through our door is restored beyond its original BMW grandeur by retrofitting it with snap rings. We machine cavities into the yoke to fit snap rings - all done in-house - to create an elegant and practical solution that allows for future U-joint serviceability. Once machined, we install non-greaseable GMB brand U-joints; greaseable U-joints are inherently weaker since the cavity inside allows the grease to travel. Our non-greaseable U-joints are simply stronger, and have been used by Beyer Driveline for 20 plus years with virtually zero issues. 

But we don't stop there.

We also replace the center carrier bearing, which is a common concern for many of our customers, especially when it comes to parts sourcing. We do understand the real lack in quality some brands offer and stay away from them at all costs. We use only quality brands such as the German manufacturer Rein Automotive, because, well, they're just darn good.

Still don't stop there.

In addition to retrofitted snap rings, a new U-joint, and a new center carrier bearing, we also replace the nose busing, any type of center connection slip yoke boot, and center ring clamp. We also rebuild the constant velocity (CV) joint: we take it apart, clean it, polish the bearing races,  and replace the boot and gaskets. 

Not done yet.

Once the driveshaft is put together, we then put it on our balancer and balance it up to 2250 RPM within 0.003" runout, but typically we shoot for 0.0015" or 0.001". Next it moves into our paint booth where it is painted with black, rust-protecting paint to withstand whatever weather you drive in. Once it's balanced and painted, it is professionally boxed up with your individual driveshaft balance report, so you can see just how well we did.

That's it. Well, actually one more thing.

Did we mention that we also do customs? Have an engine or transmission swap you just finished and need a new driveshaft? In addition to our standard service described above, we can also make you a custom driveshaft to fit into your specific build. Just contact us, and we'll send our easy custom measurement guide for you to fill out, ensuring you get a perfectly fitted driveshaft.
