I took out the front stock diff. There's something wrong with it. It's leaking grease everywhere. When I spin the pinion, it feels like the ring gear inside is warped or something. It spins freely for about 1/3 of turn, then I feel the gear mesh and there's ALOT of drag. Hmmmmmm.........Aaah well, I'm not gonna trouble shoot it right now.
This does point toward the fact that this diff was dragging the setup down though.
The RCM diffs feel sooooooooooo smooth and spin VERY freely.

Let me get this perfected. I'll show you the EXACT setup to go with and some video's. |
Sounds like the inside bearing on the pinion let go and the ball bearings are floating around inside the diff. I had the same problem with my tekno revo rear diff. It only had 3 different nitro motors and 1 hour of hard brushless running! Maybe some better bearings, boca avid etc, would be the ticket. They may be expensive, but would sure roll nicely.
