A 44000 diff housing is usually  Cast  !  36/38 are usually fabricated steel! depending on the year!

It can get more complicated than that... Several years back I researched upgrading from the 12k# front axle on an MR. Turned out the next rating up, 12.6k# IIRC, looked the same but had a more thorough heat treating.

There's also setup with a torque rod from the RR carrier housing to the right frame rail (like airrides have) on Camelback suspensions starting from sertain raiting.

I've got a set of 65K rears under my truck. Never really have paid much attention to the details of it. The axles are physically bigger than the smaller ones, the trunnion mount is massive with lots of bracing, and it's on walking beams.

44,000 is also a Mack fab. steel axle - 44k GAWR with camelback suspension gets 11mm wall thickness while with Air Suspension (HAS/AL) will get a 14mm housing.Recently Mack Engineering approved 11mm @ 46k GAWR for camelback and 14mm @ 46k GAWR for Air suspension. If you have newer version of the housings (post - 2006/2007) then you can use at higher rating.

You have a Cast ductile axle housing @ 65K GAWR with CRD95/96 carrier. This has been in production since 1945.
