As one of the Moderators on this forum, I would like to WELCOME you here...


If you are installing another Ford rear end under your F-100......it should have a tag on it.



Similar to the one shown.......this one is a 2.79 gear ratio.

IF you are using a 9 inch Ford replacement ......why not just change the center section.? ?



Just make sure you have a way of putting fluid in it......not all 9 incher are exactly the same...

Jack up one wheel, put trans in neutral, turn other wheel two full rounds counting driveshaft turns (you are only turning one wheel so it turns twice as much/fast as if you were turning both wheels equally).

it's how many drive shaft revolutions (3revolutions=3.00, 31/2 revolutions=3.50) for one 360deg tire rotation with the car in neutral off the ground and no brake drag

tire stem at 12 o'clock for 360deg refererence, drive shaft marked to count rev's and parts of rev's, hand turn the driveshaft

? never have tried xntrick's one wheel method but it sounds correct..probably cause I always jack up using the pumpkin

we're both right. With a posi you usually can't turn just one wheel. With an open you usually can't get them both to turn equally.
