volcano drive train question
 
I have a volcano S30. the right front dog bone fell out and bent. It also broke the cup next to the differential. Is the cup replaceable or do I need to buy a whole new differential?

I dont think that is the right part though.  This comes right out of the front differential. Must be some kind of a shaft that goes into the differential and the drive cup is hooked to it. The cup does not have a set screw on it. I am wondering if the shaft pulls out of the differential or if i have to buy a whole new one just to replace that cup. The dog bone musta broke the cup in half. pins are gone in the dog bone too so i know I need a new one of those.

Those drive cups have to be removed from inside the diff. You take the diff out and remove the gears from it and there is a small E-clip inside that you remove and the drive cup slides out. You need these parts.

The drive cup im talking about is the one that comes out the right side and goes to the wheel. I'm assuming you are talking about the same one Allaboutfunhobbies? Guess I will order the parts and wait till they get here. Truck is still driveable. It is just 2wd instead of 4wd. thanks for your help

Ya that's the stuff you need. The part drive cup C comes out the left and right side of the diff and the dog bones are the ones that go to the wheels.
