I'm getting all my trucks ready to take to the beach tomorrow morning, and late last night while getting them ready to pack, I noticed something amiss on one of my Slash's. The truck wouldn't roll with the motor disengaged from the spur. I had just replaced the slipper unit with the center diff, so I knew it wasn't the rear, so I pulled the front end off. I could not turn the input shaft at all.
Now, I'm crunched for time (been rebuilding the Muggy, Flux, and 8T every night for the last week), and need to source some parts at the local LHS, and I'll do the rebuild out at the beach. Anyone have an educated guess as to which parts I should pick up?? I'm almost leaning towards a whole new diff assy, and bearings.
