You can figure this out by jacking the car put a mark on a tire and a mark on you driveshaft then rotate the tire one complete revolution while counting the revolutions of the driveshaft.

Thanks for your advice.

I’ll add a bit to this to help Dave.

1) Purchase a jack. Don’t worry, the guy at the store will know what it is.
2) Block the front wheels
3) Place the jack under that thing that connects the two rear tires and raise the back of the car...after that follow the above instructions.
