The diff's in these trucks are whats known as "open diff's" meaning the torque is going to go to the wheel with the least torque required to turn it. I would take the tire off and pull the driveshaft off all 4 axles and spin the hub. If that's free, then you know it's binding in the diff. In that case, you will need to take the diff out and find out why it's not spinning and is locked up.

If it's not locked up and still spins, it may just need to run in.

If you can get us a quick video of what it's doing that would help out a lot in diagnosing it.

IMO, that looks completely normal. It still drives fine and is not locking up a wheel. As stated, these use open diffs so the two tires that are spinning have the least amount of torque. As long as your driveshafts are good. and your drive pins have not stripped out the inside of the wheels, you should be good to go.

And that thing sounds great. I love the sound in an enclosed space lol.

ok thanks for takeing a look just wasnt sure love this site lots of great info thanks agin for the help now on to the next project the team losi xxx-nt tryin to get my childhood toys back running plus i have a brand new t-maxx with the 3.3 that has only had about ten tanks of gas ran throug it should be a fun summer

Oh, the XXX-NT was a great truck. I ran the RC10-GT with the flat aluminum chassis, but thought about getting the NT. The only issue is it LOVES to melt the diff out of it if you put too much power to it. Only reason I never got one.

Just let us know what you need to know and we will help you out. And as always, videos help a LOT lol.
