M37 Rear Axle - Steel Soldiers::Military Vehicles Supersite

Anything I should do while I'm in here? Swapping out the wheel cylinder and rear brake line.. Seemed to be a little oil 'splash' in the drum, but overall, not too bad for a '54, in my opinion. Brake lining was in great shape, spring was great, all hardware moved freely, wheel cylinder was in great need of replacement... it was 'puking' brown mud... real nice. Anyone have any experience changing any of the seals in this axle? I have a handle on the brake parts, but I'm not that familiar with an axle like this. Any 'mandatory' replacement seals or hardware, such as bearings?? There didn't seem to be any excessive play, from what I can tell at least. Just thought I'd get some second opinions before I button it all up. Pics were taken after cleanup with some brake cleaner. Thanks in advance.

If you want to tackle the seals now for the hub, you might as well do them now. Its pretty straight foreward. **** you got the hard part done and thats taking those flat blade countersunk screws out to remove the drum

Yes.. and I now have the 3 replacement flathead screws, to replace the 3 I had to drill the heads off. That fiasco has a lot to do with why I'm asking this question... Anyhow, how does that hub come off? After I pull the axle shaft, what is there to do?

Well there is a Jam nut to loosten and take off,,,,,,,,,then a key'd lockwasher that slides off and another nut that preloads the bearing. If you had the dodge socket this would be easy too but it can be done with a punch and a hammer to nock the nuts loose but I would buy a socket if you plan on doing the others...........just makes the job easier. Dont ask me what size the nut is...............could not tell you as I have the dodge socket

There are 3 gaskets that you will need once you pull that shaft out and the hub off. Inner and outer hub gaskets and the paper shaft gasket. Put some sealer on the paper one as they are notorious for weeping on the 37.................esp if you dont frequently check your Vents!!!

Come on over to the www.g741.org were all about M37's

Allright, glad to see there's something to this. I kept looking at the diagram and removal/install instructions and thinking, 'there has to be more to this, with all those locks and keys..' I have been to the g741, but its been a while. Thanks for all your help!

There is a bronze bushing and seal at the hub end that's fairly easy to replace. The hardest part is getting the old out. A slide hammer works great. Sid Beck or AB Linn should have the parts. Make sure the seal is not NOS, get new manufacture. If you don't have the manual try and find one, it great.

Are you sure you are not thinking of the front axle's bushing?

No bronze bushing on the rear axle. Two on each end of the front.

That's what I get with not reading closely and dementia.
