I got my axles (8 3/4) back from mechanic pressing old tapered bearings off of axle.
He stated he had to use torch on one and got it very hot to remove ring against bearing.

Does this look like maybe it is not as strong now that its been so hot?

I sure would hate to twist an axle!

What say you, anyone?
 
Get out the hot wrench. He must have been taking the retainer off. Too late now but those can be drilled and split or cut/scored and split with a chisel. No need to turn them blue or melt them off.
 
Run it.

You will twist the splines off the other end of the axle before you will twist that part of it in two.

By the way whoever did that to your axle I would never let him touch anything of mine again.
 
Heating the axle is not the problem................the "cooling off" process is the problem............. oh sorry, did I mention axial warpage??

I would damn sure check it for trueness

I'm sure everyone knows how to straighten an axle tube???? You heat one side and it straightens out. If you heat one side of an axle it will bend. I'm not saying that's what happened here but you never know????
 
It was glowing at some point based on those heat marks. Which means it got hot enough to change the hardness. Whether it actually changed the hardness or not is anyone's guess, and will depend on how it cooled. But it's a very real possibility that axle is no longer as strong as it's supposed to be. Whether or not that's a problem for you depends on the application. And whether or not the axle is still straight.
 
if your around a machine shop check the rockwell hardness in the affected area and in a non-affected area see if the hardness matches. if you know someone who works in a machine shop you should be able to check for free. only takes less than 5 minutes

If I was to go to a machine shop, I`d have them chuck it in a lathe and check flange run out. You could test this installed if you have a indicator.

That is very unfortunate, I could almost bet money it is bent. I have seen it happen before and you really can't get them straight again. If it is warped you might want to call Strange, Mark Williams or someone that makes axles and ask them. If you are .002 out at the axle flange you have to figure it at 14" out from center to see how much run-out you have.
 
Drdiff.com, new axle set, $300-ish area, green bearings, stronger than stock axles, home run, why waste time and money?
Go fetch self a pair.

You could check it with two V-blocks and an indicator, at least within .003??:

yup 2 v blocks and an indicator would be the best way to check it. not in a lathe. a lathe would involve too much time spent setting it up with a steady rest and would basically be accomplishing the same thing as the v-blocks
 
Never in my life have I used a torch to do that. I've pressed off a crap ton of them too.

In the old service manuals they show grinding them down almost to the axial and then taking a chisel and popping them with a hammer to crack them then they slide right off.

Yup. I'm lazy. I've always just pressed them off. They come right off.
 
I guess if your really lucky you may just have center bores on the ends you can use to help you check runout.........
