I'd get alloy front shafts first.

I blew the rear pinion gear and noticed pitting on the stock hats around the area of the wheel bearing so im replacing em.

Why would you suggest doing the fronts first?

Well, all the parts for the rear axle are slowly coming in various ups shipments.

After a long argument with the parts manager at the local jeep dealership i was able to purchase a d44 pinion and ring shim kit. (it amazes me how dumb computers seem to make people)

Alloy usa came through with the chromoly shafts. (happen to include bearings, seals, and wheel studs)

Buddy happened to have a set of 4.56 gears that were NIB purchased for 50$

Managed to destroy my bearing retainer plate on the driver side. So, ordered some beefed up plates from scoutparts.com. Those should arrive tomorrow afternoon sometime.

Now to read up on how to reinstall all of this correctly.. I keep hearing rebuilding differentials is best left to an expert... Bah, those experts were novices too at one point.

That's amazingly in depth, yet simple to understand.

Well.. After 4 weeks of weekend tinkering i have the rear end re-geared. I put the new Alloy USA axles in... and i come to discover the hub of the shaft and the tire side face of my rotor are the same diameter.



So.... Ya, im stumped.

Anyone have an aftermarket disc setup on their alloy shafts?

Maybe it's the camera but the bolt circle looks bigger. 5"? JK axle maybe?

They're 5 on 5.5 patern and the shafts are for an 80 international scout ii. The original brake setup was off of an 87 ford thunderbird. Don't know if that'll help anything.
