x4te Diff.

[Fletch]

Hi,

I've just finished building my x4te and found that the diff. screw lossens during use leaving me with no drive and when I've tightened the screw it's stripped the thread in the nut. Has any one else had this issue?

I'm considering an upgrade to the team c gear diff. if this keeps happening, has any one had any experience making this upgrade?
