So i had an issue with my earthquake where after about 5 mins of run time, all the power would go to my front wheels, i thought my differntial was done considering i tore the care apart and couldnt find a loose screw anywhere (loctited everything when i got it) so i assumed something in the differential, i picked up a new diff from a local redcat dealer and when im putting the screws in i noticed that the second i tighten them around the diff case the differential stops spinning completely, lossen them and it spins fine, im confused because i dont wanna seal the differential and put it back together and when i go to run the truck see the rear wheels not spin and get stuck taking it apart again,
