I have gathered some small info about axles and so that might be useful for others.


DANA 25/27
These Danas are indistinguishable in appearance. The military Model 25 has a thick, cast cover, while the 27 and civilian-model 25s have a thinner cover, will accept taller gears, and backed V-6s.
The Dana 25 and Dana 27 front axles were used in:
Jeep CJ2A, CJ3A, CJ3B, CJ5, CJ6, MB, GPW, M38, M38A1, and M170 from 1941-71.

Dana 25/27

DANA 28
The alloy-case Dana 28, with a 6 5/8-inch-diameter ring gear, came in Bronco IIs and Rangers with anything but the 4.0-liter engine. Although 4.0-liter trucks come with Dana 35s, most of the front suspension and/or drivetrain needs to be swapped to replace a 28.

BRONCO II FRONT 83-90
RANGER FRONT 83-90 ,93 & UP

DANA 30
The Model 30, with a 7 1/8-inch-diameter ring gear, was the standard front differential in some 1972-75 CJ-5s and all 1975-and-later CJ-5s and CJ-7s. It is still used in the front of Cherokees and Comanches, and will probably appear in the front of the Grand Cherokee.

DANA 35
This axle, with a 7.56-inch ring gear, is the fronted for 4.0-liter Ford Rangers and Explorers/Mazda Navajos. The 35C version is found in the rear of Cherokees and Comanches.

Dana35

DANA 35c
The Dana 35c has a 7 9/16" ring and pinion and uses one piece axles (2.625" in diameter). Starting in 1990 Jeep switched to an inferior C-clip Dana 35c. The "c" in Dana 35c does not stand for C-clip, it stands for custom. They are custom because they are shipped incomplete from the Dana factory to Chysler and Chrysler completes the build. The two versions have different shafts, bearings, and carrier. There is a C-clip elminator kit available for the Dana 35c. The Dana 35c is probably on the small side for hard four wheeling with larger tires and lockers. If these are your intentions, you might be better off swapping in a Dana 44 or better.
Early YJs built from '87 until '89 used a 10" rear drum instead of the 9" drum used in the later YJ and TJ Dana 35c. The axle in the picture above has the 10" drums.
The R&P ratio ranges supported by the carriers are 2.73-3.31 and 3.55-4.56.
The Dana 35c is the axle used in all YJs (Wrangler) from '87-'95 and it is the standard axle in the TJ (Wrangler), ZJ (Grand Cherokee), MJ (Comanche), and XJ (Cherokee). The Dana 44 is an optional axle on the TJ, ZJ, MJ, and XJ. Some XJs were built with the corporate Chrysler 8.25 axle as standard. The TJ and ZJ versions are coil sprung, the XJ version is leaf sprung (spring over), and the YJ and MJ versions are leaf sprung (spring under).

DANA 41
The 41, which has a ring gear size similar to the Dana 44, came in early CJ-2As. The spiders are the same as a 44's, but the carrier and gears aren't. It is almost universally swapped out in favor of a Dana 44.
The Dana 41-2 was used in the CJ-2A after serial number #13453 in early '46 and it was used in the CJ-3A until serial number #37549 (late '50). Looking at the diff cover, it appears as tall as a Dana 44, but not as wide. It was also used in Willys Wagons and Jeepster VJs during this time period.

DANA 44
All domestic manufacturers have used Dana axles, and the 44, with its 8 1/2-inch ring gear, is likely to be a step up on anything smaller than a 1/2-ton. A narrowed 44 could be the hot ticket for vehicles smaller than a full-size sport-utility. It was standard under the front of pre-1976 Chevy Blazers and 1/2-tons, solid front-axled F-150s and Broncos, and Jeep J-10/J-20s and Grand Wagoneers.

DANA 44-IF
The Ford-version Dana 44 Twin-Traction-Beam setup is similar to other 44s (ring gear diameters are identical), but there are no axle tubes and the "cover" is actually the suspension arm. It's standard in the front of any TTB-equipped Ford except the F-250HD, which uses a Dana 50.
Vehicle Model Year:
Ford Bronco, F-150 1980-96

Dana44-IF

DANA 60
A Dana 60 looks deceptively similar to a Dana 44, but the 60's 9 3/4-inch ring gear diameter is a major factor in strength. It can be found in many 3/4-ton pickup and van rear ends.

DANA 70
Almost identical in appearance to a Dana 60, the Dana 70 is standard in heavy Dodge pickups and GM duallies. The large 10.54-inch ring gear diameter will tolerate much torque, and is suitable for diesel power and/or big tires.

FORD 7.5-INCH
The small Ford rear end, which sometimes uses a fiberglass cover, is found in Bronco IIs and non-4.0-liter-powered Rangers. For bigger tires and/or engines, it's usually swapped for a Ford 9-inch.

The 8.8-inch debuted in 1983 Broncos and F-150s, and is now found also in 4.0-liter Rangers and Explorers/Navajos. It is easily distinguished from a 9-inch by having a cover on the back. Year (81-97)

FORD 9-INCH
The venerable Ford 9-inch is both readily available and strong. Later models have bigger axle tubes and stronger housings. It was standard under 1966-88 F-150s and Broncos. It also came on many vans and the Lincoln Versailles (a popular axle for swapping because of the Lincoln version's disc brakes with parking brake). Year (57-87)

FORD 10.25-INCH
Ford's biggest axle comes with semi-floating shafts in 1983-and-newer F-250s, and as a full-floater in F-250HDs and F-350s. Applications are similar to the big GM 14-bolt and the Dana 70. Year (83-97)

GM CORPORATE 10-BOLT 7.5" & 7.625"
The GM 10-bolt is named for the number of bolts on the cover; ring gear diameter is 7 1/2 inches. Variations of this can be found in the rear of GM S-trucks and some Isuzus, and in the front of S-trucks.

With a 10 1/2-inch-diameter ring gear, the biggest 14-bolt GM rearend looks much like a Dana 70, and is but a few thousandths of an inch shorter in ring gear diameter. This axle is commonly used with big engines and/or overly large tires. It was used under 1973-99 3/4-tons and 1 tons

AMC MODEL 20 American Motors
Used in 1976-and-later Jeep CJs, the Model 20 rearend is both strong and weak. An 8 3/4-inch-diameter ring gear provides strength; weaknesses are the housing itself and the axle-to-hub retaining method. Converting to one-piece axles or full-floaters gives this axle better stamina.

CHRYSLER 9 1/4-INCH
Mopar's 9 1/4-inch rearend can put a stop (notice the octagonal stop sign cover shape) to rearend woes on many lesser-equipped vehicles. Chrysler has used these since 1969, on 1/2- and 3/4-tons.

I did some update on the 35/35c section, explanation of the difference and added a pic to describe where to find the codetag. This is also related to the exploder138's commanche question. The pic is huge, I know..;) But the small thumbnail in the upper right corner needed to be seen clearly...

White95Explorer: thanks!
