IDENTIFICATION:
Tag Identification:
D30: “30” cast into back of diff casing on top right and left next to diff cover. Tag bolted on diff cover with axle ID and gear ratio.
D35: “35” cast into back of diff casing on top right and left next to diff cover. “C” next to “35” DOES NOT stand for c-clip, but “custom” (unfinished by Spicer). Tag bolted on diff cover with axle ID and gear ratio.
D44: In most cases “44” into back of diff casing on top right and left next to diff cover. Tag bolted on diff cover with axle ID and gear ratio.
D60: Similar looking casing to the D44, except the oil fill plug is elevated to provide more fluid for the larger gears.
Chrysler 8.25: Tag wrapped around passenger side tube with axle ID and gear ratio.
Ford 8.8: See Joe Dillard and T.Dome's writeup linked at the bottom of the page

Differential Cover Identification:
AMC 20: 12 cover bolts, round cover, fill plug not present
D27: 10 cover bolts, oval with straight sides, distinguished ring gear extension, low fill plug
D30: 10 cover bolts (five on top, five on bottom), oval cover w/flat sides, fill plug just below centerline
D35: 10 cover bolts, evenly spaced, oval "dome" shaped cover with low fill plug
D44: 10 cover bolts, hexagon shaped cover with very round edges, fill plug on centerline
D60: 10 cover bolts, hexagon shaped cover, fill plug on centerline
D70: 10 cover bolts, hexagon shaped cover, fill plug on centerline
Chrystler 8.25: 10 cover bolts, oval shaped cover, fill plug just below centerline
Ford 8.8: 10 cover bolts, square with very round edges, fill plug not present on cover




Gear Identification:
If the gears are unidentifiable from the tag or if the tag is missing, there are two methods to find the gear ratio.

1) Spin the tire one full rotation and watch how far the driveshaft rotates. Double the amount the driveshaft rotated, this gives you your gear ratio. Be sure you are spinning the tire forwards.

2) Count ring & pinion gears: Count the number of teeth on the ring and the pinion. Then divide the ring teeth by the pinion teeth to attain the gear ratio.


And thanks to:

for some changes.

1) The AMC20 that came under the CJ is a different animal from the one that came under the waggie. A waggies pumpkin webbing is different, tubes are plug welded in to the housing, 29 spline. I think 2.21 was also a gear option -- I think. One perc to at least the waggie version is the massive pinion - the shaft is the same diameter as a D60.

Where the fuck did you get that information.

You missed about half of the D60 front axles, And you listed the ones you posted as closed knuckle, with drum brakes. Spline count is wrong as well for most of the 60's you posted, Most have 35 inner, and 30 outers, but easily upgraded to 35 outers.

Have you ever even seen a front D60?

I'm not even going to comment on all the Rear D60 variants that you missed.

The rest of it looks pretty good, but before you copy and paste some nonsense on here, at least read it to make sure it's accurate.

I found your info useful. I was thinking of putting a 1996 8.8 in the rear of my YJ, or a older D44. I'll change the axle shafts on witch-ever one I end up with.
But now I hope I end up with the 8.8.
