I have read and the more I read the more confused I get. I got a pinion depth setting tool and understand how to use it (for a dana 80). The problem I have is, it says if I have a + to remove shims or a - add shims to the pinion to get the correct depth. I do not see a number anywhere on the pinion other then 5.812 this is on a USA Standard gear set. It's going in a puller and I have been thru 4 sets in 10 passes. I feel the pinion is not setup correctly but backlash is 0-.002. So can anyone tell me how to read the 5.812 number since there is no +/- number on the pinion?
