The axle where the bearing rides is pretty worn. The standard should be 1.062 Should I replace it? There is also a lot of pitting on the tapered part of the axle. What do you think?
The axle should be replaced, but when they are worn like your's is the axle housing is bent. Be sure to check the housing's for run out before you replace the axle.
What is "run out"?
I would replace that axle shaft.
Stephen
The run out is how much the axle housing is bent. I have seen them bent a 1/2 in. Very seldom that one is not bent at all. They have been around a long time.
Do you have a link on the forum that I can review as to how to determine if the housing is bent and how much?
Put the axle together without the outer bearings. See if the axle shaft comes out centered through the hole where the outer bearing mounts. If not, she is bent.
When I did mine, it was off at least 1/2 inch. I had The Tin Shed out in California straighten it for me. They did a great job.

Hi Scott, I wanted share something you might already know, but just in case..... I bought a T that had a rebuilt rear last year. The REPO axles are apparently a little longer than the original. That means I cannot get the wheel on. Now I have to send it out to be ground down or try and fix it myself. Just a heads up. Bob
Robert, why does the extra length of the repro axles hurt. I thought they are 1/8 longer to allow a little more room for the brake shoes, or worn wheel hub tapers. I do not see how the extra length wood keep the wheel from fitting. Im going to need new axles soon so any problems you have encountered would be of interest. Thanks ..
Donnie, you are correct. I've replaced axles on two different cars now with no issues with the longer axles. At best, the drum sticks out a bit further but from what I've seen and read, that doesn't hurt.
Donnie, I am not a good one to explain the problem. I am told the repo axles are to long. There have been others on the forum with the same problem. But then there are those who have had no problem?? You can see by the picture that in my case the drum does not cover the brakes (there are no brakes on the car in this picture.)
Lang's has new axles in both standard length and longer ones, so you do have a choice. Snyder's has only the longer ones. I don't know about the other vendors.
Here is a link about axle housings.

Look for my picture with the washer on the end of the axle.
What does the other side look like?
I am just thinking maybe your carriage is off center?
You have a 1/16 longer axle, .062-50, and your gap is well over 1/4 or .250 thousandths!
Even with a new hub, that shouldn't be, unless a new hub would be off.
Herm.
Many times the inside of the hub has some metal from the previous axles galled onto the surface. You need to clean up the inside of the taper to make sure it fits. The extra length of the axles is not a problem. The extra length is divided between two axles so each hub is only moved out 1/16th of an inch. That is less than the diameter of pencil lead. Maybe your center carrier is off, the housings are off, the hub taper is bad, some other unknown is causing this but the axles being 1/6th longer is not it.
Scott and I looked at these today. We checked both axle shafts in both housings, then switched them to check again. The worn shaft shows run out in both housings, while the other shaft looks good (very little run out) in both housings. With the wear on the one shaft, and poor threads on the other, I'd suggest new axle shafts. Then the housings can be checked again with shafts that are known to be good.
If it were me, I would use the standard length axles if I could get them. I like to stop in reverse so I don't have Rocky Mountain brakes. The extra length might come in handy with RM small drum brakes but adding a shim would be a lot less trouble.
Thank you for all the input and suggestions. Axles have been ordered and can't wait for Fed Ex to get here. @ Dave, Thank you for your help and second set of eyes. Can't wait to take your '15 out for the first time with you. Happy New Year to all.
