notched cross pin 8.8, which one?
whats goin on guys, well im ordering my 4.56's either tonight or tomorrow from complete off-road, and they offer 2 notched pins for my front diff, ones a 3/4 notch and ones a 7/8 notch, which one should i get? they are both the same price? thanks
edit: it says the 3/4 is for the 28 spline and 7/8 is for 31 spline, now does anyone know which one the front diff has on my 02 f-150?

Yeah, most people agree that notched pins are not strong enough, especially for use with a locker. They recommend grinding a small portion of the ring gear to let the pin pass through the carrier.
Grinding does not weaken the gear at all because the gears mesh in a patter near the center and not on the egde where you need to grind.

I also ground a small portion of the teeth where they block the pin from entering the carrier, well I had the shop do it anyways. One reason was because I'd read the notched pin was weak, and the main reason was because I was having the Eaton e-locker put in and you can't use a notched pin with it.
This was on my rear 8.8, but I don't see why it would be any different for the front differential.

Update on my thread hijack, lol: I just talked to Auburn and they're sending me a pin for free. Great customer service over there. If you call Auburn, hit "1" on the phone and talk to Nancy, and she'll consult with an engineer named Jamie or Jamey about it. Very helpful and agreed the documentation I received was wrong. It's a small crew for Automotive Products support over there, which tells me that they don't get too many calls to deal with probably. That's a good thing.
If the pin isn't enough to remedy it, I'll get back to them.

I know I used the right pin -- but it must have been the wrong grind.
I put it in the right diff -- but it just didn't quite align.
I know I did a good install -- but I should have ground the tooth off.
I heard from Andy Roach now -- but you know he's just a ****-off... [oops...]
