Axle Grinding!!!!!

[swamped2a]

i have a nylint crawler i wheel it everywhere but now the front axle grinds and slips when i try to go up an object how do i stop the grinding and make it 4x4 again?

 

[STS]

take the axle apart and tighten up the bolts connecting the motor to the gear box.

or it might be the little gearbox support has broken an ear off//

if thats the case just stuff something between the box & axle housing on opposite side of axle gear//
it will push the gearbox into the axle when you put the housing back together.
