Does the markings look okay too you on the instructions it says centerd but its ok for them too be close to the toe witch is the inner part of the gear but both of the marks seem to be centerd toward the toe if i take shims out or put in it move them markings to higher and lower that seems to be the centering of the 2 marking. Opinions would be greatly thankful.

It seems to look a little tight. Maybe try a thinner pinion support shim. Be sure to keep the proper bearing preload.There shouldnt be any shims except for the pinion support. Good luck

I just sent you a PM. Keep us posted. I used the word "tight" for lack of a better word. Sorry if that threw you off.

That's not to bad of a pattern.. It should be toward the center of the tooth..But you may not be able to get it there. I have tried, and tried to get there and couldn't..and put it in the car looking like yours, and it worked ok..

Ok thanks there aint much more i can do if i take shims away it moves the pattern off center either way adding or subtracting shims. Really thanks for the replys of i was to losten the pinion nut then that would change the preload so i couldnt do it like that and i can move the diferintal over to the left or the right. Cuzz then it would change the backlash. lol so pretty much there aint much i can do. On the instruction sheets it says it ether is closer to the toe or slightly toward the toe and that they are. On another sight ford trucks site it has a mark chart. and it says on there that there is too much heel bearing. I have no clue what a heel bearing is or even if they make one.
Any more reply or any help from anyone is very helpful i just need to make sure or to fix the problem.

i went to a machine shop and he said that the coast side doesnt really matter but the drive side has to be centerd. Because thats where all of the force is.
Here is a drive side picture

I have a related question on setting up a Ford 9" please...after everything is assembled including the pinion yoke, what do you all use to seal under the pinion nut to keep the lube from leaking out? I read somewhere that all you need to do is goop it up with some permatex sealer under the nut and torque it to keep the lube from following the yoke spline and leaking past the nut. Is this correct? I replaced the pinion seal in mine and there wasn't any washer under the pinion nut so I used Permatex.

Thanks,
Dan B
