Ok so i got my TC3 out yesterday and not to my surprise the same problem as last fall was still haunting it. My differentials get loose after a min or 2 of running to the point where it feels like i hardly have any torque. I am running a Novak 5800 in it. Maybe this motor is too powerful for stock diffs.??? What kind of part(s) would I get to fix this. Also my front diff was rebuilt just pry<5 runs ago. Thanx any help is appreciated

Try putting in a new locking nut on the diff bolt. Might want to use locktite too.

Stock, as in stock PLASTIC diff outdrives? If that's the case, then that's the problem right there. Just get a set of steel outdrives & you'll be good to go(the lightened ones for the TC4 should drop right in, & they work very nicely, I have a set of them myself). Those plastic outdrives tend to heat up alot when you put alot of power through them(like you're doing with a brushless motor, those outdrives even get stressed from a brushed 19 turn motor, & yours is more powerful than that), & as they do, they can loosen, the slots can spead(which has happened to me alot when I used the plastic ones) & they can even melt if you're not VERY careful(done that too, ). But the steel ones will hold their setting well, & best of all, they're practically BOMBPROOF, so you can install, set 'em & forget 'em....

Have to agree with JW and say try a new locknut first.
Failing that then steel or ally diff halves - IRS make some nice blue ones.

i ran 9 turn motor in my tc3 finally blew a diff after close to 2 months of racing. that was with the stock plastic outdrives. i would go with a new springand a new diff nut. the diff nut might spin in the out drive that houses this nut.

FYI - check out EBAY for the outdrives. There is this one guy who is always selling off HG stuff, usually wheels, skidplates, and....TC3 outdrives
