Was out hitting some jumps and rolled my x, now it wont move. The engine runs fine and the wheels spin if its in the air, but if i put it on the ground and push it it wont move. The Spur gear is fine and spins fine. Any one know what it could be??

Mr snuggles

see if the spur slipper is tight.

check if the pins have fallen out of the cups in the center driveline (front and rear driveshafts)

Spur gear could be stripped.. or the motor shifted and the pinion gear isn't making contact with the spur gear.

Checked the spur gear it is working fine. When the wheels are off the ground the wheels will spin but if i put the truck on the ground it will move a little then stop. And the gears all line up fine also.

I think you may have busted either a ring or pinion gear at either the front or rear diff,

set the truck ontop of a box or something that allows all 4 wheels to hang in mid air,

then grab one of the front wheels and hold it still while turnig the other front wheel,

see if there is any binding or locking up, if not then try this same procedure at the rear wheels,

let us know if you find anything.

Sparky i did that and the front spun up to a point and then stopped and the back did the same. Im pretty new to the hobby so not sure if its normal or if that means there bad?
