Grinding axle shafts

Well as I have found out from a broken warn premium hub my passenger side axle shaft is a little to long. The shaft was riding on the backside of the hub and chewed up the threads for the "free" or "lock" cog to ride on. How much can I take off of this stub shaft? I am guessing that with the splines I should have it done by a machine shop right?

I know people who have cut them with a chop saw. Im not saying you should, but it can be done that way if you go slow and keep it cool. You should be able to cut a 1/4" or so

I've done it before without any issues. Take your time so you don't put any excessive heat into the shaft, then dress the splines with a high quality triangular file.

I had the same issue with my 60 shafts. I Cut them with an angle grinder and a cutoff wheel. Go slow and it shouldn't effect the heat treat. Cleaned and dressed the splines with a file.
I cut as much as I felt I could without weakening the circle clip shoulder.

from what I have read no c clip should be okay. I have read that Ford Super Duty's with auto hubs axle shafts did not have a spot for the c clip or snap ring and that Warn states it is okay to run without it.

Did it fix the issue with your hub getting smashed?

It is a common issue as you know, but I am pretty sure there is a part number for a warn hub dial that is shorter (doesn't stick so far into the hub) that would be way easier than grinding/cutting down the stub... I think it is just a dial from a 30 spline hub that you put into the 35 spline hub body.

They're not too bad to cut, as has been said. Grinder + cutoff wheel, you'll be done before you know it. It will take much longer to take stuff apart and put it back together, than the actual cutting.

This is interesting especialy since I am only in need of one new hub.

I never smashed a hub per-say but the shaft would grind against the hub. Cutting it fixed the issue.

Ultimately, I broke a 35 spline Warn premium on Eagles Nest, got it warrantied and bought a set of drive flanges from Carl (when he was still at Tera).
I don't feel that the locking collar is strong enough when you factor in the higher strength of an alloy shaft. It just seemed like some cheap cast piece: I stripped all the interior splines... it did nothing to the Yukon alloy outer.

Cory did the same thing to a 19 spline D44 warn premium with alloy outers.

I will say that I'd rather blow a hub than a shaft, but I think most hubs are only as strong as a stock shaft. I'd love to see a vendor step up with a hardened locking collar for use with alloy shafts.
