So after crashing my car and replacing the part, (cracked a caster block and bent suspension pin) my car wont reverse. after programming/calibrating it again (i originally thought it was the receiver/transmitter being dumb , so i swapped over to my dx2e and still get the same problem), the car just takes off in reverse. any suggestions on what to do?

Swap any two of the 3 motor wires

nope, same problem. the only difference is that the direction it's constantly spinning is reversed
