Do I have a diff. problem?
 

So after rebuilding my Assoicated B3 I have found that when you hold the car up and spin one wheel the other one spins in the same direction. Now I can't be sure, but I'm pretty sure that's wrong. Although the car still runs just fine. The other wheel should spin in the opposite direction correct? What might my problem be?

yes, when you turn 1 wheel by hand, the other will go in the opposite direction
I don't know why, but that's how a diff works

Yep I feel retarded now lol. Mus not have had the clutch plate tightened at all.

LOL, Have you ever taken a transmission apart? When you open it, you will notice that the diff/thrust balls spin. That is what causes it.

Yea I have taken them apart, even actually built one for a lego robotics thing, but I'm still a bit fuzzy on how they actually work.
