Full-Size Jeep Axle Identification!

This is a VERY common question on this forum so I will try to break this down for the masses:


1974-1979 Full Size Jeeps:

Front Axle:

Passenger Side Drop
Dana 44 (6-lug) or Dana 44 HD (8-lug)
The 6-lug axle comes in both narrow and wide versions (Wagoneer is narrow, J-truck and Cherokee Chief* is wide)
The 8-lug is wide only
1974-1975, disc brakes were optional in these years. In 1976, disc brakes became standard on the front. (EDIT!! They were still optional in 1976!)


Rear Axle:

Dana 44 (6-lug) or Dana 60 (8-lug)
The Dana 44 comes in narrow, wide and wider. (Wagoneer would be narrow, Cherokee Chief* would be wider and J-truck would be widest)
All of the Dana 44's are offset, some are offset less but all are offset

The Dana 60 is widest only and is a little off-set


1980-1985-ish Full-Size Jeeps:

Front Axle:

Driver Side Drop
Dana 44 (6-lug)** or Dana 44 HD (8-lug)
**1982-1984 (6-lug only) could have a vacuum disconnect front axle - I have seen some 1985's with this as well.

Rear Axle:

AMC 20 (6-lug) or Dana 60 (8-lug)
AMC 20 (6-lug) offset just a tad. This is much stronger than the CJ versions. This axle has 1-piece axle shafts stock and the tubes are thicker for use in the heavier Full-Size Jeeps.
AMC 20 Axles come in narrow, wide and wider. (Wagoneer and Grand Wagoneer would be narrow, Cherokee Chief* would be wider and J-truck would be widest)

Dana 60 Rear offset just a tad and comes in widest.


1986-1991 Full-Size Jeeps

Front Axle:

Driver side drop
Dana 44 (6-lug) or Dana 44 HD (8-lug)
The 6-lug axle comes in both narrow and wide versions (Grand Wagoneer is narrow, J-truck is wide)
The 8-lug is wide only

Rear Axle

Dana 44 (6-lug) offset just a tad
Note, some early 1986's have been spotted with an AMC 20 rear axle.
Comes in narrow and widest versions (Grand Wagoneer would be narrow, J-truck would be widest)

*Cherokee note: Some 1974-1983 Cherokees can either be narrow or wide. This link will help break this down: http://www.bjsoffroad.com/cartgenie/....asp#Widetrack

Good question, here is a rundown:

1974-1991 ALL Full-Size Jeeps were Spring Under Axle in the front

1974-1991 ALL Full-Size Jeeps were Spring Over Axle in the Rear

Thanks, I am looking at buying a 79, and will probably be talking to you about springs.

Try that as well, i've never looked too much into it, but it breaks down the numbers for q's on what gearing is in your axle.

Get it off the ground and do the math based on driveshaft/tire revolutions or pop a cover and count teeth.

I'm buying an 82 Dana 44 front from a cherokee chief to upgrade my 95 YJ,the guy said it is a 6 lug...2 questions...
1.is it a high pinion?
2.does anyone sell axles to make it a 5 lug to match the YJ lug pattern?

I will be putting an 8.8 from an explorer in the rear,i would like to keep that lug pattern for the fact i already have 3 sets of rims and tires for it as is.

All my questions are because the guy am buying it from is a guy i work with but he is almost 2 hours from me and we are workin 6-7 days a week,so i haven't had time to go look at it yet.

No, it is not a HPD44. Jeep never used them. Only Ford, and Ford never used a 6x5.5" pattern.

I've never seen a hub kit to get to 5x4.5" and there probably isn't room to re-drill them. This is a common problem that people face when trying to upgrade a YJ with an 8.8 since there is no easy 5x4.5" front solution.

Wanting to retain your rims & tires will doom you in this effort. There are few routes you can take.
  1. Buy a TJ Rubicon D44 front.
  2. Give up on the bolt pattern and buy a matched set of 1986-up Grand Wagoneer D44's.
  3. Skip the D44 front and beef the D30, eliminating the CAD.

My suggestion would be to abandon the 5x4.5" pattern and buy a matched set of axles, such as the 77.5-79 F-250 HPD44/D60 that bolt into YJ's SOA.

Personally, I wouldn't bother with the Chief D44. Too wide and you'll burn $ shortening it that could have been better spent elsewhere. Get a Wagoneer or Grand Wagoneer D44 front (~61").

Thanks for the info,i guess i'll just go with my original plan and use the set of axles out of one of my early broncos,have a junked 77 bronco with dana 44 disk and big bearing 9" rear,was just trying for an easier route to keep the lug pattern.

Ok, after looking through this thread, I know that the Jeep I'm getting is an 8 lug with a HD d44 in the front, and an offset d60 in the rear, but what I don't know is this: What would the spline count be on those axles, and are lockers for a D44 universal for d44's and the same for the d60 provided the spline count matches up?
