How hard is it to remove the axles on a '51 M? I have the wheels and tires off, and if it is a halfway painless process I want to try to remove the axle housngs and replace those gaskets because they leak! If not, I'll just pressure wash it and go on.

So how hard is it?

Thanks
 
Pretty hard. Removing the PTO, there is a hole that you can work through to remove the bull gear retainer bolts (see archives for many posts on this)
BUT a good repair can be made by loosening the flange bolts and getting about 3/8" space to clean the old gasket out (carefully, and perfectly).
Then cut the very top of a new gasket and wrap on to the axle flange. (use non hardening #2 permatex on the gasket, thin film on both sides, and a dab where the cut was made. It makes a good job of a hardship. JimN
 
I replaced the gasket on my 400. I did not think it was real tough. Just take your time. I found the most difficult part to be to get the bull gear off the axle shaft.(after removing PTO) I put a spacer between the two axle shafts and then unthreaded the bolt from one shaft, which then pushed the axle out. I was very fortunate that I did do it that way, because the inner bearing needed to be replaced.

I had thought about doing it as Jim mentioned, and had I done so, I would not have found the bad bearing. Which I thought may have been why it started to leak. Then again it was most likely to have been caused by years of water freezing in the rearend.
