Jeep Axle: Dana 44


Several variations of the Dana 44 have been used as the rear axle in Jeeps, all of them use a 8.5" ring and pinion. The Dana 44s used with CJs are one piece shafts with 30 spline axle shafts.

The R&P ratio ranges supported by the carriers are 2.87-3.73 and 3.92-5.89. Not all ratios are available for all the variations of the Dana 44. Common ratios for the CJs were 2.73 and 3.31 but was available in 3.54 and 4.11

CJ Dana 44

Starting in 1972, the Dana 20 transfer case was used which has the rear output shaft centered, so the rear axle has the differential in the center. From 1972-1975 the Dana 44 was used with a 30 spline flanged axle shaft. This Dana 44 uses 11" drum brakes and the most common ratio is 3.73.

In Late 1985 and all of 1986, CJ production was coming to a close AMC 20s were in short supply, so they used wide track Dana 44s in some of the '85 and '86 models. Bolt on compatible with any '76-'86 CJ, but wider than earlier narrow tack AMC 20s. Use of the Dana 44 in 1986 began somewhere between serial numbers ending with 049379 and 054173.  Common ratios were 2.73 and 3.31 but was available in 3.54 and 4.11

All CJ Dana 44s use a 5 on 5.5" wheel bolt pattern.

 

 

Other Dana 44

The Dana 44 used in the military M38, M38A1, M170, Willys Wagon, and Willys Pickup was the same was the version used in the CJ vehicles during that time period. Willys Pickup and FC trucks had a couple others optional rear axles used with models with higher GVW. The Dana 44 was the light weight model for the Willys Pickup and FC trucks. All these Dana 44s use a 5 on 5.5" wheel bolt pattern.

The Dana 44 was standard in Wagoneers, full size Cherokees, and J series pickups. A wide track version was introduced for the Cherokee and Wagoneer in the 80s. The Cherokees and Wagoneers built from 1974 on use a 6 on 5.5" wheel bolt pattern. Models built before 1974 used a 5 on 5.5" wheel bolt pattern. Most rear ends before '74 use the weaker 2 piece shafts, but some of the later ones uses 1 piece shafts. The early Wagoneer and Cherokees used Dana 30 and Dana 27 front ends.

The Dana 44 used in the '72-'73 Jeepster Commandos with the one piece shafts is an excellent low buck swap from '76-'86 CJs. It bolts right on, has 30 spline one piece shafts, and is narrow track width.
