that could be possible, if i were you i would take a really close eye on your mesh and listen to it too. pick up the truck and spin the wheels by hand and check to see if every spinning part is spinning smoothly. the gear mesh, cvd's. check to see if your motor is mounted on the motor mount correctly, make sure it nice and straight, if its a little off it wont mesh good with the spur and cause vibrations. anything can cause vibrations, just check it. Maintenance and these types of check ups will allow you to have many years of trouble free bashing.
