At Oshmo, we can replace your worn out spline with a NEW Siebenrock spline.
The factory ring -gear/spline is a two-part pressed and welded together component. The correct way to repair a worn spline is to machine the spline completely off of the ring gear. See Spline Operations tab above.
You can send us your ring-gear or the entire final drive. Click on the Options tabs for pricing.

OPERATIONS – installing new spline to ring-gear
The ring-gear/spline is mounted to our lathe to machine away the factory weld.
Next we heat the assembly in our oven to 350 deg F.
The heated assembly then goes to our press where we chill the internal shaft and press off the old spline.
The ring then goes back in the oven and heated to 350 F
The ring gear in its heated state is ready to receive the new spline. The spline is pressed in place and held under pressure until it reaches room temperature
The final step , we weld the spline to the ring gear like as it was originally done at the BMW factory.
