Is it normal for my spur gear not to spin freeely
I was wondering if it was normal
is the spur gear on my tc4 supposed to be hard to spin
well not hard to spin it just deosnt spin freely and makes a lot of noise

In this case, the best thing you can do is post a video or have someone local to help you.

With no motor in the car or the pinion moved away and the drive shaft removed it should spin very free by spinning the spur with your finger. Check the front input cup also, that should spin nice and free too. If it doesn't you have either a bad bearing somewhere in the drive line. If it does spin free. make sure your drive shaft is seating properly. there should be a little bit of play.

its not my spur gear
the tension is on the motor
i just took it off and spun it
try to picture this
i spin it about a little less then a 1/4 turn and it stiffens up
i "brake" that tension and it spins to another stop about 1/4 turn away
im thinking it could be with the magnets inside the can and this is normal maybe its a komodo 19 by the way
its kind of hard to see in the video but every time i stop my fingers thats when i get that "stiffness"
and itll still take a little to processes on youtube

motor
take the thing apart and make sure there is nothing inside the motor and clean your bearings then put it back together but after you clean the bearings let them dry and then oil them and then check and see if you have the same problem , if bearings are good then i would make sure bearings are seated properly in the can

I may be losing my mind,but im pretty sure in your video you are spinning a pinion, not a spur. If thats a brushed motor, then it is normal bc the magnets are causing that.

the bearings seem good
im thinking its something normal
im gana take it to the shop when i get a chance
this way actually have eys seeing it instead of reading it
but you guys where super help
thanks thanks a lot

it is brushed
the spur spins freely with no noise when the motor not in place
but with the motor bolted on it makes so much noise and gets stuck a little when i lightly push it with my hands

If it's brushless, then that's normal. It should make a clattering sound when the motor is geared to the spur. But when the motor is on and running, it will run smoothly. Now, if you remove the motor, then the diffs should run freely, and with no resistance.
