When I roll the revo back I hear a grinding and feel resistance, I think its coming from the CB / Spur meshing.

Its not the tranny because when its rolling forwards all 4 wheels move smoothly. What could this be? Gears aren't stripped or damaged as far as i can see and I've tried all different spacing's for the meshing. Out of idea's!

Twisted chase may be the cause where is the sound comming from more info plz if u want our expert help. Thank
 
I gave all the info I could.. :? what else would help you diagnose?
 
so the tranny gears inside are ok?? that would be my first assumtion then i would check the mesh and then if all else fails check the clutch
 
i guess its the clutch that needs to be looked at. What inside could be causing that noise and rubbing.
