Parts for Dana-Spicer Model 30 Front Axles in 1972-1986 Jeep® CJ and 1971.5-1977 IHC Scout II

International first used the open knuckle Dana 30 with the new Scout II which which replaced the Scout 800B in mid-year 1971. Jeep followed a year later with the redesigned 1972 CJ-5/CJ-6 Universals and Comando. Jeep would retain the Dana 30 all the way to the end of CJ production in 1986. International, however offered an optional Dana 44 starting in 1972. Most sources state the Scout did not use the Dana 30 after 1974, however, International Parts Books do not list an end date for the Dana 30 and Spicer axle catalogs do show International used the Dana 30 as late as 1977 so there may be a few special production or base model 1975-1977 Scout II Dana 30 axles out there.

Axle Shaft Seals (Inner Oil) and Seal Kits

top_page
product note
On 1972-1986 Jeep and 19Dana 30 front axles, an Inner Axle Seal is pressed in the inboard end of each axle tube, right next to the differential side bearings. These seals contact the inner axle shafts to prevent gear oil from running out of the differential and down the axle tubes. Old age, blown axle u-joints, and/or grit that works it's way into the axle tubes and cuts the seal are the usual causes of failure. A bad Inner Axle Shaft Seal can be detected by oil coming out the end of the axle tubes next to the axle shaft u-joint. Usually when these Seals start to fail, they will seep oil so the leakage may go unnoticed for quite some time. Many a ring and pinion set has been burned up from axles that lost all their lube when long term seepage was not seen. Replacing your Inner Axle Seals requires axle disassembly up to and including removing the differential. The axle seals are then driven inward into the center housing. Installing your new seals is easy IF you have the correct tools we show below. Otherwise, it can be a real WITCH!

Axle Universal Joints

product note
Jeep used a Small Axle Shaft Universal Joint on 1972 to 1986 CJ Dana 30 Open Knuckle Front Axles. For replacing these small 1-1/16" u-joints, we have only one non-greaseable choice as the small cross will lose too much strength if drilled for lube channels

Ball Joints

top_page
product note
The 1972-1986 Jeep Dana 30 Beam Type open knuckle front axle uses replaceable Ball Joints pressed into the steering knuckle. Both Ball Joints are weight bearing. A threaded adjuster that screws into the upper hole of the axle yoke is used to provide preload on the Ball Joints. Dana has modified the seal configuration on the current production parts, but the high quality and basic Ball Joint design has remained unchanged since the early 1970's. Over the years we have found the average Ball Joint life of our non-greaseable, factory Dana Ball Joints to be 7 to 10 years for vehicles used as daily drivers and/or work vehicles

Gaskets and Gasket Makers

top_page
product note
In the mid 1970's Dana made a differential cover design change to heavy gauge covers with flat mating flanges. Unlike the previous, thin gauge covers with embossed flanges which were made for use with a cut gasket, the new design, thick gauge covers are designed for sealing with RTV. If you desire, you can still use a gasket with the new type cover by combining the gasket with thin films of RTV. We stock both Ultra Gray RTV Sealant and genuine Dana Diff Cover Gaskets

Spindles and Spindle Nuts

top_page
product note
Jeep CJs with manual lock-out hubs or solid drive flanges use the same four piece spindle nut parts as the World War II military MA and MB Jeeps. A thrust washer is used between the outer wheel bearing and inner spindle nut. The inner nut adjusts the wheel bearing end-play. The outer nut functions as a lock nut, it is held in place by a bend-over lock washer located between the two nuts. Vehicles with Warn Lock-O-Matic Hubs require special lockwashers and round outer nuts

Wheel Bearings and Seals (Individual)

top_page
product note
Drum brakes were the only front brake option available when the open knuckle Dana 30 was introduced for the 1972 Jeep CJ and Commando. Drum front axles use smaller inner wheel bearings and wheel seals than those used on 1974-1977 Scout II and 1976-1985 Jeeps axles equipped with disc brakes. Three different front wheel Seals were used by Jeep for disc brake models. The ID and OD of these Seals are the same, however the width and lip design will vary by year. The outer wheel bearing for all drum and disc brake axles is the same. For the inner bearing, drum brake axles use the same bearing as the outer, but disc brake axles use a higher rated bearing with a larger ID bore
