This bearing is one of the reasons that the 9-inch has the reputation for being bulletproof. The narrowest production 9-inch axle is 56. And the axle tag says 4. While the iron is molten, magnesium is added to increase the shear strength of the alloy. These third members are the strongest of the production cases and the most desired.
There may be a second dash and more numbers and letters on the top row if there are specifics that are unique for interchange information. Many companies, such as Currie Enterprises, Mark Williams Enterprises, Moser Engineering, and Strange Engineering, reproduce this design today. I have also spent many hours in scrap yards and visiting and interviewing the experts in this field along with years of building numerous axles myself. Inquire directly with our sales agent at 1-800-378-7566 for options and availability. Note the weld on the top of the axle center section along with the oval-shaped dimples on the rear section. They can be hard to see through the rust or undercoating, but like I said earlier, it is also on the silver tag.
The identification process begins with locating the factory rear-end tag and then using visual methods. There is a machined roller bearing race on the pinion head portion that points at the differential opposite the tapered bearing races. The axle housings themselves had many different variations over time as well. Thanks for the help guys! The 8-inch was introduced in 1962 and is found in many lower performance Fairlanes, Mustangs, Falcons, Comets, Cougars, and Pintos, just to name a few of the applications. Both open and limited slip differentials were available.
These tags are typically quite beat up, twisted, and rusted over the years. They will need to be replaced before installation. Here is a quick visual summary: The 1957 housings do not have dimples on them and have an oil drain plug. This pinion has the tapered bearings and collapsible spacer in place. It is underneath one of the nuts that holds the third member in place. The most important is the model, or service code, found in the upper-left corner. It typically takes us approximately 3-5 business days to process a credit back to your account and 2-3 business days for the credit to appear on your account.
The code, 4L11, tells us that it is a 4. The unit on the top left seems to be nodular iron but requires a little more investigation to verify. . Note all returns and cancellations require a prior authorization. There were many instances of cuts and scratches from the thin steel tags sticking up on the axles. No problem, we will replace it at no cost to you. Just remember to add friction modifier if you change rear axle fluid.
This is by far the most common axle used by restorers, hot rodders, customizers, and racers. We can ship anywhere in the contiguous U. These were used sporadically until about 1969. Unless you are building a Pinto or straight six-cylinder vehicle, you want to avoid it. These axles did have metal axle tags similar to the 9-inch axles but they were slowly phased out as vehicle programs were updated.
Both axles share a common design and are often referred to as banjo style or third-member style. There are quite a few companies making Ford 9-inch housings to fi t just about any muscle car out there, including non- Ford vehicles. This complex fixturing and welding process, coupled with fuel economy concerns, is what eventually led to their production demise. None of which changes the strength of the axle shaft. These variations include different-size drum brakes, disc brakes, and wheel hub arrangements.
Common items that are not guaranteed include but not limited too nuts, bolts, links, seals, bushings, ball joints, brackets, bezels, wiring, cables, sensors and other applicable items depending on the part. If you need a special motorized platform Liftgate to lower your order to the ground, we offer it for free upon request at checkout. All of the 8-inch case nuts can be accessed with a socket.

The door tag says c2 which only thing I could find is dana 61 but only listed f250 and not my e350. The third reason was basic health and safety concerns for the assembly technicians and other employees who handled the axles in the manufacturing and assembly plants.
Written by Joe Palazzolo and Republished with Permission of CarTech Inc. I have included the narrow 8-inch axles for reference. The cast-iron third member is installed from the front of the housing. The only dual wheel configuration we have seen is on F350 duallys with the small gas V8 engine. For additional information, call our sales experts at 1-800-378-7566.
