terrible grinding sound

[scarletboa]

maybe it's the motor's "notchiness" you are hearing. is it quieter when you are driving the truck at 5-10mph?

Or just set it on the ground and give it a hard shove away from you. If the "grinding" noise goes away but you still hear the gears, and then comes back when the car slows down, then that's it. It's normal for motors with slotted stators to make this noise.
