u can check the moter by hooking it to the leads of the ones that u know works if its the moter replace it if its the speed controlit coud be a bad soder joint or a burnt out esc at wors case change the esc.

gonna have to crack open the rear axle, see if something is broke. maybe as simple as a loose pinion set screw

try turning 1 rear tires while holding the other. if you can, then the axle will need to be opened up as the diff locking part is missing or broken. both wheel should turn together as the diff is locked.

if they do both turn together, then i would open up the motor cover. see if the pinion is meshed with the spur, or if the pinion is loose on the motor's shaft.
