SJ Axels



Tom,
I'm 99% sure of this, the wagoneer axels are the same width from womb to
tomb (first model to last) variations are in the bolt pattern and brakes
(early ones use drums with 5 on 5.5, later ones use discs on the front with
6 on 5.5), J trucks (Gladiators, and the J100, 2000, 3000, and 4000) are
all about 4" wider in track width and some of the heavy weights may have a
5 lug larger circle (like the dodge PWs or early IH trucks) the J10s and
20s were pretty much the same width with disc brakes and a 6 lug on the 10s
and 8 on the 20s (although, some J20s had 6 lug axels, not sure about the
rest of the components, probably really a heavy half ton). In about 80 the
rear axels went from D44s on the J10s to AMC 20s, these are not the same as
the ones used in the CJs and are in fact a good rear end with one piece
axels, you do need to gusset the tube to pumpkin joint (but on a racer you
would anyway).
Ratios are to numerous to talk about, D44s can use almost any ratio.

Of note: Some Very early J trucks may have an oddball set of axels, like a
dana 53, these are not ones you would choose anyway due to brakes etc. Also
the military version of the J truck (M715) used a Dana 70 front and 80 rear
in some applications, but with the large 5 lug bolt pattern and drum
brakes. also some rear axels (d44) used in quadra trac applications have an
offset diff, may not be a good thing!

Short version, Wagoneer/Cherokee (std or 4 door model)  => all the same width
	      J anything/ cherokee wide track => 4" wider than wagoneers,
other wise the same width.
