So, I have a 28 spline 3:73 geared 8.8. But the fbody axle is to small of diameter to fit the 8.8 spider. Anyone run into this before? I thought the axle from an fbody would fit a 28 spline 8.8 carrier.
I have never put one of these rears together with factory axle so this is a first. My friend had me put a conversion together, but was wanting to keep the cost down until after school. Any help is much appreciated.

The tag on the 8.8 was wrong! I removed the side and spider gears from the carrier and counted the teeth. 31.
So, now I'm wandering if I can simply change the side and spider gear to 28 spline gears. Any one know? Or where to look to find out
Thanks

I don't recall where but I read you can't just change the spider gears between 31 & 28 carriers.

Damn. That's not cool. Monday Ill have to find out for sure. This sucks, because I put new bearings on the carrier. I have a new 31 spline carrier set up I could have used.
Thanks for the reply Hiltsy

I've got a 28 spline 8.8 rear out of an 03 mustang...id be willing to trade you diffs...I am gonna go 31 spline. Which diff do you have?

Trac lok from an explorer. I just put New koyo bearings on the carrier and pinion.
Where you located?

I thought of using my stock axles with an 8.8 swap, then I read the axles are not quite the same in the c clip area. I forget the exact difference, but I remember reading that the c clip doesn't engage quite right. I plan on ordering custom axles from Moser when I get to that point and would suggest you do the same. Why put this much effort into it and then cheap out on $400 for axles?

Cheep out? That much effort?
I built the rear over the weekend for a friend. The rear in his car ( only car) is almost done. Building the housing is easy. I tried to save him a few bucks by using a 28 spline rear, only the tag on the Rear was not correct. Just attempting to keep it simple until after winter ( Christmas )
