d44 axles odd design

the end of the axles on my rear 44 in my cj has open holes right into the brake drums
they're cast into the shafts where it sticks thru the middle of the drum, you can see the brake's workings thru the hole... not sure why it's like that, not sure if that's normal but it's factory design not jimmyrigging
is there supposed to be some sort of plug in those holes? i don't like havin things gettin in there

The hole is to access the bolts that hold the bearing retainer and backing plate to the axle housing.

If memory serves the place that I could see into my brake drums
was through the adjusting hole. I remember this becuase I couldn't get the drum off and that was only place to peer into the drum.

This is why. There are supposed to be plugs in them but usually once they are taken out they don't get put back in. When you have to remove an axleshaft, you'll be happy that hole is there.

This thread is an amalgam of confusion. There is one fairly large hole in the axle flange so you can stick a socket through it and unbolt the axle retainer nuts (like someone said). This hole is never plugged and there is no reason to do so. When you put the drum on you can't see any of this.

There are holes in the backing plate to access the brake adjuster wheel. These have oblong rubber plugs in them which sometimes fall out. You can get replacements at any auto parts store if you are missing one.

This is not always true. I know for a fact that if you use AMC 20 drums on an narrow trac 44, the hole is visible.

I think he is talking about the 1/2 moon machined in the face of the axle flange where the drum slides on. My 73 Dana 44 had this. It would be a place you could pry the drum off the axle but I wouldn't do that. If you can't get the drum off you need to crank the adjusters in until you can. Anyway, I always thought it was there to prevent the drum from completely rusting.stick to the axle.

I had a Dana 44 out of a 74 Jeep Commando and it had plastic plugs in the flange holes but I can see where they could come out easily and get lost. I guess the purpose of the plugs is to keep crud from getting in the brakes.

Edit: I still have the shafts from that rearend and I can see that even with the brake drums installed, a portion of the hole is exposed. Kinda like my AMC 20 with 1 piece axles.

YES, There IS supposed to be plugs in those holes.

They look just like thin 'Freeze' (Core) plugs.

They are about 1-3/16", but you will probably have to get a 1-1/8" plug and spread it out with a socket or something before you install.

Someone that can navigate the Jeep Parts Web Sites can probably turn them up at one place or another and post up the link...
Some guys we have here are REALLY good at finding that strange little stuff like that!

would be cool if someone found that... i'd much prefer to not get crap in there if i could help it
tried 2 parts shops, one was closed, first 2 didnt kno what the hell i meant
i'll drive to one soon as my wheel bearings are put in and my insurance renewed... btw thanks for the front wheel bearing write-up jeephammer, using it for my job, fantastic info!


plus mine's an '83 that originally came with a 4 cyl, now has a 350... i'm aware of no '83 4 cyl that had a dana 44, which mine does
its about 55" wide wms-wms, would that be an original cj axle out of a different one?

Here's my CJ-5 with AMC 20 and 1 piece axles. I guess it wouldn't hurt to find a plug to fit that hole.
