I agree. You will most likely not have a problem with soft-packs (assuming your track allows them) but having watched my Habu melt into the ground, it's just one less thing for me to worry about.
When they get damaged, whatever they are in is a write off. I would hate that to be my rc truck.
I'll give it a shot next time I happen to have both cars apart.

Hmmmmm, I backed off all the diff mounting bolts to make sure they weren't pushing through, but it isn't smooth. I moves (i.e. not caught on anything) but it isn't anywhere near 'free' spinning. How freely should it move?
If I use my thumb on the spur I can maybe get 1cm or so of movement.

I don't know if you are building a kit or not but I ran into this today on the kit I am building. I built my diff's and installed them only to find that one of them would not turn free at all. I forgot to put the gasket in the diff while building it, so I disassembled to install the gasket and discovered that one of the small screws that holds the diff together was not completely seated, it would turn, but not smooth. Once I tightened the offending screw the diff turns fantastic.
I hope this helps.


Or put it on the side of the receiver box and shave some of the center part of the chassis off that divides the two.......

My spur gear feels very hard to turn and when i pull on the belt it feels very tight with no motor.when i remove the belt the front and rear spin very free like a b4.is this normal or could it be belt tension to tight.also the outside of my belt is fraying.any ideas?
