Help, weird rubbing noise in reverse
my mustang was on a steep gravel hill and I tried to back the manual up in reverse and it wouldn't move on the gravel. the tires kept spinning and the rpms were almost redlining.
now, when in reverse and mostly OFF the gas, i get a weird rubbing or grinding noise that has a "beat" to it as if it only happens during a rotation. i also hear it going forward at high speeds, but only when not on the gas.
WHAT could have happened to it in reverse on a gravel hill?
thanks for any help...
