From my thread on helping me identify my M38 body you will know that I started looking for a M38 chassis to replace the CJ currently under it. Well I found what seemed like a promising donor. Problem is, Im not going to take it apart. Other than the 12V conversion, carb and roll bar this thing is pretty nice and original. And its early, like I wanted. I didn't expect any of this when I went to inspect it, but wow. There is not one spec of rust on this jeep, not even in the cowl battery box. Being an early production, all that hard to find early stuff that I accumulated for Franken Jeep will now go back onto ol yeller.

So the plan has changed, Franken Jeep will continue to be a M38 on a new CJ chassis and I will keep it up at Camp Lockett where I like to explore.

This one will be returned to M38 trim throughout. Im not going to do a 1000 pt restoration either, I want to enjoy it!

It's amazing what you find when you aren't looking for it.

Back from travel. Got a place all sorted out for the new Jeep in the steel building.

Im going to do a couple of things. One is to fix the janky brakes, the other to just start inventorying what is there, what isn't and what is wrong, or incorrect. I think I;; do a better job photoing everything before anything is touched.

The brakes have started easy enough. Came apart nicely, inside looks generally Ok except first wheel has a rusted cylinder. One side completely siezed.

Well, unless it's a flightline rig it's the wrong color....

Brakes are done. All went very easily. One thing though. Got to the rears and the first side I did was just as the manual said it would be. Had to remove the dust cover and loosen the axle nut, then apply a large puller to pull the drum/hub combo.

But got to the other side and as I was getting ready to apply the puller, I noticed that the drum could be removed separately, just like the fronts with the removal of the 3 1/4-20 flat head screws.

So did this come along later? Or is this an A1 set up the made it into this side?
I'd like to duplicate it on the original side, as pulling that hub is a royal pain in the rear.

The good news is that other than the seized wheel cylinders everything else is like brand new inside.

EDIT: I went back to the manual, and frankly its a mess about the rear axle brakes. The instructions say to pull the hub, but the illustration shows the drums that just come off with the three screws (even calls out the screws). The odd ball drum/hub I have has the drum on the backside of the hub and the wheel studs are driven in from the back semi-permanently joining the drum and hub.

The M38 & the M38A1 with the Dana 44 rear axle both use the 3 screw type drum retention system.

The Late CJ2A and early CJ3A used the Dana 41 rear axle which uses the drum retention you described with the drum inboard of the hub.

I would suggest you first determine which axle you have then use the correct drum set-up for that axle.

Hello Wes,
My M38 has a 41. It also has the screwed on brake drums.
Was that a later CJ mod?

Thanks,

Mine has a 44 in there.

Wonder why the manual is so hosed up about how to take off a drum?

Parts list is no help either, it calls out 4 unique assemblies that include the drum and the hub, one for each corner.

Shouldn't be too hard to find a decent M38 hub and drum, I want originals

EDIT: Something is fishy! Your illustrations are close. The M38 drawing you show is how one of mine is. The other labeled CJ2A is different from what I have. Mine has the hub that takes the pressed on dust cover.

The left side hubs have left hand threads. So knowing the Army you have four different hub assemblies.

My guess.

The best way to keep this sorted out in your head is Dana/Spicer Model 41 the brake drum is inboard of the hub and retained by the studs. Dana/Spicer Model 44 the drum is outboard of the hub and retained with three flush screws.

The change from the 41 to 44 was a Dana/Spicer change not Willys or Kaiser.

It has always been suspected that some very early M38's came with 41's. The six pilot model M38's came with the wwII and early CJ2A style full floater rear end the Dana/Spicer model 25-2.

Willys dropped the use of the 41 in 1948/49 on the open bodied jeep series but many were still stocked on the production line.

The TM's and ORD's address the 44 except the very first M38 TM 9-804 which shows a 44 rear axle but all references to the drums/hubs are clearly 41. So the manual with confusion issues is the TM 9-804 and the rest are correct by showing only the 44. The illustration is from the CJ service manual and is a CJ2A mdl 41. It is quite possible the M38 version of the 41 came with sealing caps for the ends of the shafts.

This would be the ideal moment for you to post detailed photos of both sides of your axle and it's rear cover and model stamp.

This is what TM 9-804 has to say about the drums"

TM 9-8012 says three countersunk screws retain the drum on pages 251 thru 253.
