a few days ago i crashed into a concrete parking lot stop thing, that resulted in a bent shocked shaft, its bent pretty bad and and looks like if i hit any harder i would've broken a piece off the bottom of the front bumper, tonight was the 1st night i actually inspected it after installing my new front drive hub. i plugged the battery in and had full throttle and brake, but there's no reverse. also, b4 i connected the front wheels to the center drive shaft, and notice they both spin in the same direction when you spin 1 while the rears spin in opposite. i don't remember the front spinning in the same direction. is my front diff messed up and is that the reason i have no reverse or is it something else?
