This is what it looks like on the inside and the damage



This type of damage is prone to N54 DCT cars when drag racing them where wheel hop occurs most.. It is perfectly ok in roll racing as long as there is no wheel hop
Got my brand new driveshaft and my mechanic went to install today and this was not my failure. The spline shaft that comes out of the differential sheared so now I need a new differential. Now I am trying to decide if I should change my gearing and go with a LSD. Any thoughts?
