And we also chalked it, and came up with one wierd end result...with the truck off we jacked up the rear tires, put it in drive and calculated a 1.5 per wheel turn(it also is not a posi as both wheels did not turn at the same time). It did not make since as common sense you dont have to multiply or divide to get a more accurate answer so yea that was a doozy.

 

That would be your spider gears splittin up your rotation. If the tag is present , i would assume its was correct, and back up that assumption with your tach at road speed
