Joe, if your diff is loosening after every race night, I would think there is a possibility that there is a thread worn somewhere in that diff. It might be that you need a new diff, or the parts that are threaded replaced, plus a new hex head screw if that's used to tighten it.

I don't run your car so it's hard to tell without knowledge of it. I would be happy to take the diff off you this Friday, strip it down and give it a full inspection before putting back together and dropping off at the model shop for you to pick up on say the following Sunday morning.

I'll have a good look to see if there is any visible signs of where, if not, I'll re-grease it with diff-lube and see if it works the following week.
