Checked the run out on the rim today and found it was 70 thou out of true.
I pulled the wheel and brake drum off the stub axle and found 40 thou run out in the stub flange. The axle is ok only 5 thou in it. The flange has two high spots opposite each other and two low spots inbetween the highs. The brake drum rocks when put on the stub flange. So it definately has a problem.
Does the flange come away from the axle or is all one piece. Looks like it should come off the shaft. Took the split pin and nut off, but couldn't budge the flange with a puller today. I will do some investigations.
I put the wheel back on but found that by rotating it 90° a few times I could reduce the run out to 35 thou. So the rim is out too. Double problem evident.
I checked thd manual and the stub flange does come off the axle. Does any one have the correct tool. Or does a modern puller do the trick.

Oh dear. I took my car to an axle specialist who did trucks as well They called me and said they could not press off the flange with a 10-ton press. Did I want to go to the 50-ton truck press? Soaked it in diesel for a few days then tried it on the 50-ton press while heating with an oxy. They said when it came off, there was a seismic event in the area.

You probably need to get another axle, pull out the current one, and get it into a press to get the flange off. We put the flange on my new axle, and set it up in vee blocks to check runout. The axle I had was second hand and from memory, there was about 10 thou run out.

Someone with some more experience may be able to add to my experience.

Hi, I'm a bit late on this but for what it is worth.
The flange can get distorted when people use a great big press to get the flange off the axle. If you are using a press you should ensure the flange is all (or as much as you can and as close to the axle as you can) resting on the plate on the press to get a full surface to take the load. If you only sit it on two sides it can distort the flange and actually tend to clamp the flange to the axle as it distorts. Also always screw the nut back on the axle, loose, so that when the flange lets go, it will retain the axle and prevent it from shooting across the shop. They do come off with a bang.
The best way is to use the correct puller if you can get your hands on one. You fit this to the flange and then tighten the center bolt as tight as you can then give the end of the bolt a sharp clout with a lump hammer. It just falls off or at least always does for me.

Hi Brian
Yep I love to try one of the correct pullers. They look like they screw onto the large flange thread. Don't suppose anyone has one handy.

Its a lump of a puller and attaches to the hub by the four wheel studs. the secret is that a pressure is applied to the axle/hub while a good sharp blow is applied to the axle. If you had a press that applied pressure and was able to strike a blow to the axle then that would work. Unfortunately it will not on a hydraulic cylinder.
A normal press relies on brute force to separate the two parts and that force can be quite substantial.

The churchill type tool looks to be the one to use. I've been looking at a few forums to see what people use. As you have said. A nice load then an impact is usually the best way. I have to find out if I can source one or make one. Thanks Brian

Looks like your flange is already distorted so you will need a new one,i destroyed both of mine with a 20 ton press and yes they do come off with one hell of a bang good luck

I got them from Moss Europe, they don't come with studs so you will need new ones at the same time.
