as you can assume from the name of this post, i have a problem with my differential. it goes really rough when distributing unequal forces in the tires, resulting in that both turn exactly at the same speed. what do i have to do to stop this? does it need more loob? thanks for the help

You need to take the diff out and strip it down to see if any teeth are damaged inside...

Thats the most likely cause for a diff going notchy...

If its just been built then maybe the shimming is incorrect also
