When I shimmed the diffs I used 8mm shims, between the diff cup and the bearing. It took a lot of them. FLM only gave you one shim that would go between the housing and the bearing, which i used on the ring gear side. Reading the Forums here, I think these shims are 16x14mm. I seen some 16x13 mm shims linked somewhere that I ordered. I hope that these will work to shim the bearing closer to the diff cup. Because right now the bearing is what is keeping me from using the stock axle on the one side.

How well do the stock axles hold up? I really think what happened here to break this was the axle was not inside the dogbone cup enough, but there is no way to get it in any more. In the front the pilliow balls are all the way in and its the true track in the rear, so theres only so much you can do.

This was really discouraging, I just got this all together and its broken in a few minutes.
