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.

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.

Looks Good MiniB...

 

I think some of the time size recommendations could be shifted some with the addition of higher spline Chromo shafts and upgraded u-joints etc... still a good starting point for "stock" stuff.

I know according to what I bee reading the 8.8 is good up to 40's. So I can keep the 8.8 and run my 37's. Just need to up the 30 to a 44 now. Anyone?

Problem is, there's no easy way to do it. It either requires a lot of work, or a lot of money (or both). :(

I figured eariler on a full spool 4.88 and alloy shaft with c-clip elimanators for the 8.8 and figure a 44 with lockouts for the front and upgrade as well the shafts and for my wheeling style should get a few good seasons out of them.

Then if need bigger to to go to a real frame.

 

Or hey you know I could win the lottery. :fool: Well have to play first I guess :doh:

IMHO, C-clips eliminators and lockouts are both overrated. If they come with the axle already, so be it, but I wouldn't pay for them. My hubs are only used on the road because I have that stupid minispool up front (which I hate and am removing) and you have to break a shaft before the C-clip becomes an annoyance. Good luck with that. :thumbsup: And take some video of it happening. :clapping:
