8.8 TTB

It's about to get funky in here.

This will not be quick, it will not be pretty. It is mainly here to satisfy my own stupidity/curiosity.

Feel free to offer comments. I will steel the ones I like and ignore the others.

Feel free to make fun of this. I know I will.

I have thought the 9 inch with a currie or dutchman housing welded into the beam would be slick. Gearing a differentials would be limitless. Only thing standing in my way is cubic dollars. Combine that with Roberts new brakes and dana 60 hubs but for a dana 60 spread on the ball joints - bomb proof.

Easiest way to put the 8.8 mounting pattern in the beam and get proper ring gear clearance and protection?

Maybe not the cheapest route, but really quick and easy.........

I am currently north of Kansas city on the Missouri side. This will mainly be a Colorado rig with the occasional snow day use here. Maybe if I'm lucky it will get out west some.

Ok, fun acts.

Diff weights.
8.8 51#
D44 70#

Axle diameter
8.8 1.325 Exploder 31 spline
D44 1.275

Axle centerline to diff face
8.8 1.675
D44 1.804

This means the OX diff cover will sit up 1/8" on the inside of the beam, this will make a few things easier. The diff cover is 12#. If you were to use a regular fabricated diff cover there would not be any real gain over a over a plated and gusseted normal beam.

I started but didn't finish (yet) a similar project. I was going to retain the D44 and it was going to to in a Ranger. I was gonna use U joints on the long side (where the phase would cancel out most vibrations) and a CV on the short side. If I was gonna modify the beam to fit a different 3rd I would have started with a 9.75 IRS but I'd be surprised if the 8.8 gave you any problems in that vehicle.

I would ignore steering other than making the basic geometry not too terrible, build it a lot of adjustment and then tune it how you want it.
'94 F150, XL trim, 8ft, 133"wb, 4.9L
rear locker, open front, 3.05/8
manual steering, 2:1 quickener 12+ turns lock to lock
(8-lug front and rear-ttb project on indefinite hold)
(have most of the parts for a manual swap, NP435 or Clark 280vo)
