I was doing some maintenance on my rustler and while I was at it I figured this would be a good time to open the Diff. and re-grease it.
Everything was going goog I got all of the old grease out re-packed it put it all back together and everything was spinning nice and smooth. I re-installed the tranny back on the truck and everything still worked perfectly, however when I hook the drive-shafts and wheels back on I loose the differential (I hold the spur and turn one wheel and the other spins the same way).
I have gone through the whole process three times now(just to make sure I didn't miss anything), and every time the end result is the same.
has this happened to anyone else ad what was the solution???
