Narrow track offset differences

My original set of axles is from a unknown year wagoneer w disks, I recently acquired a second set of narrow track axles (drums)as part of a parts package and I pulled the shafts and notice that my shaft lengths are different between the two axles when did this change.

Front or rear? In 1980 the front went to driver drop and rear went to AMC 20 so that might be a difference.

Rear, one is a 74 rear, the other is a 79 rear

Ones has shaft lengths of 21.375+27.875=
49.25
the other is 19+30.375 =
49.375

Both housing are the same bearing retainer flange to flange or real close to it +/- .125

Sounds like you have a quadratrac and a part time transfer case rears. The q-tracs were offset, more than the part time axles.

Both should be 44's, so the flanges and outer stuff should be the same, they just moved the diff housing

A 6-lug Dana 44 centered rear axle is both scarce and sought after. A drum brake Dana 44 front axle can only be '74-76; front disk brakes became standard in 1977. These Jeeps all had rear drums.

I think you are measuring differently from how Jeep measures. The right axle from a '74-79 manual transmission Jeep (part time) is 25.24" OAL. The Quadratrac axl (full time) is 22.78" OAL. (I presume it's OAL, not shaft length)

He said both were rears, so if a disc setup on one, it was converted somewhere along the line.

I should have added I was not measuring overall shaft length I was measuring from the back side of the bearing to the end of the shaft where it engages with the diff.

I was doing it by myself and that was the easiest way to get it done to compare lengths/difference.

When I said drums I meant front, should of been more clear.

Well I cleared a spot on the healing bench and got my square out and did some measuring. I definitely have a centered d44 from a manual fsj.
