I took off the front of my 4x4 traxxas to replace a screw that was hard to get to. I think there might be a problem with the shaft or some of the gears when I put it back together. There is resistance and the shaft does not want to spin. I just tried to roll it with my hand and can see it kind of skip like one of the gears does not want to spin. If I watch the shaft as I attempt to gently roll it it does not move then kind of skips when I roll it.
I obviously do not want to try to run it like this as I am sure I will destroy something. I am a rookie that bought a used truck trying to figure out what to do here. Any help would be appreciated as I am a little over my head with this problem.
