Well today I was running my EMBE on stock batteries ( li pos haven't come yet ) but I wasn't even close to half throttle and the trucks front diff locked up... I took the front drive shaft out and tried it to make sure nothing else was hurt and it run 2wd again less than half throttle and i heard a clicking noise and I was about to turn around the truck and the rear diff locked up.. I was not on it hard and it did run on 2wd for less than 30 seconds when it fully quit.... Now it just spins the spur gear and it goes nowhere... I think it's the tranny?? Also I wonder if I should replace the diffs just to make sure nothing was hurt??? Also I know the front diff is ok because it freed up after I took the drive line out.. Does any one have ideas why it happened??
