Be very carefull when you hear that noise that sounds like a bunch of marbles rolling around. It could be the differential pin or pins have come loose! If it gets loud you are going to have to pull the trans before you bust the case. That's what mine did.
I have 2 sho's 1 with the keyless entry pad and 1 without. Can I put the door from the one with the key pad on the one without and make it work? Is the wiring the same on all Sho's?
