When the truck is on the ground and you gently push it with your feet it makes a crackling sound as if the engine is being resisted in some way. After that initial push, everything seems to be smooth again. I had noticed when putting on the pinion that the engine shaft end did not spin smoothly. Anyways, is this something I should be concerned about, or is it normal? If my explanation was like "wth?" I can always post a video!
Thanks,

is this a factory team truck? or is it ball diff equipped?
if so, its the ball diff slipping.
otherwise, its cogging, turn the start power low, or upgrade your batteries..
the resistance while spinning the motor shaft is perfectly normal, its a 4 pole motor.
