Something wrong with my motor or ESC

[Acksaw]

Hey guys, put in a new battery on my LRP SXX TC V2 and LRP Vector 6.5T motor and with any sort of load (as in car on the ground) it seems like the motor cannot output any power. It appears to make a noise like 2 gears struggling against eachother.

Could this be the sensor gone on either the motor or the ESC or perhaps one has gone? I can take a video if required.
