problem today while running....need ideas as to cause..

[magman]

Running my mbx-5T w/a ccneu mmm combo on 5s. Using 80% of throttle on radio, 40 punch control, low start power, stock spur 16T pinion

I was running in the street, grass today doing a few small wheelies, speed runs, nothing to harsh and all of the sudden after 10 mins. the truck acted as if it had a slipper clutch and it was slipping. It was very noticeable on start-up and if I gave it full throttle. Took the center diff out and the truck rolls free forward and backwards with no binding.

Neither the spur or the pinion are stripped..Motor spins free w/ pinion on and does not bind.

So I am thinking it is the center diff....
