PostSubject: Full-Size Jeep Axle Identification!   Tue Jul 09, 2013 5:42 pm

*Note* This information was taken from a member on Jeep Forum.



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
