Later model Dualmatic-style-Free-Lock hubs. The name was originally part of the Free-Lock Hub Corporation

Ann’s longtime friend invited me to look at a jeep yesterday that they just inherited from her uncle. They were confused about the model, so hoped I could identify it.

From the front, the jeep was clearly an early M-38A1 (turned out to be a 1953), with the hinged grille and early fenders. The dash was also correct, the correct large hole fuel inlet, and it had the early M-38A1 cowl with screws. However, it also had a tail gate that didn’t appear added. The body itself was in great shape, yet the body wasn’t mounted using all the holes, in fact some holes were missing. The cowl also lacked both the “JEEP” stamps along the side of the cowl AND the passenger side indent common for M-38A1 bodies.

Thankfully, the uncle had kept receipts, one of which was an invoice for a replacement body. Aha, that’s why it did not have JEEP or WILLYs stamped anywhere.

But, more interesting to me than the jeep, was that another document they had was an original set of instructions for Free-Lock hubs (more on Free-Lock Hubs), the style that looks just like the Dualmatic hubs. This is the first time I’ve been able to document that at some point Free Lock branded hubs were made exactly the same as Dualmatic hubs.

As you can see in the two images below, we have basically the same set of instructions for both hubs, with one that is labeled Free-Lock and the other Dualmatic. The Dualmatic is dated “8-28-74”, which the Free-Lock has hand written instructions, which I believe indicates the Free-Lock hub instructions were from an earlier date.

These two pics show a few more details, including that there are two sets of screws on opposite sides of the hub.

    I have a set of these on the CJ-6, but I know they aren’t free-lock. Could be dualmatic, but I know I have seen “Sears” branded hubs exactly like this too.
