Leaking Gear Diff

[chet]

It seems pretty normal in 1/10 for gear diffs to leak. I would say Losi is the worse but my 210 gear diff leaks a lot too.

I've tried the shock oil rings from a 408 instead of the cheap black ones but the seem to bind.

Anyone have a fix or something to help? Mine leaks out of the ends from the black O-rings.

If I run heavy diff oil when I run on high bite carpet tracks it doesn't leak to bad. But if I'm running 1000 it leaks really fast.

cheers
