Brake shop could be trying to charge a new tool to your job, OR it might be a different rear axle than you thought. As for the front axle, it easiest to tell by looking at the hub. If it is the size of a Dana 60, then it is a Dana 50 TTB, if it tapers down, it is a Dana 44 HD.

I really dont know what rear end I have Im going off what was stated earlier in the thread. According to that I should have the 10.25 but I dont know off a way to really verify. Id like havin the heavier rear end so Id know I could trust my truck to haul most anything I would need to

Realistically, I do not need a full floater, BUT I like the peace of mind. Look for a fill plug in the rear cover to see if it is a Dana or a Sterling 10.25. Either one are good axles. Refer to the previous picture for a picture of a full floater. A lot of the full float and semi float do not need special tools to remove the drums. If the hub and drum come off together, then all you should need is a special socket. Has the brake shop tried to remove the drum without removing the hub?

Most likely they did. And I think Im doin my own brakes from now on so IF they really needed a special tool I would to. Now you said a fill plug in the rear cover you mean the pumpkin or the ends of the hubs? And if 1 is present which 1 is it?

I think the dana 60 rear has the filler plug in the cover and the 10.25 is in the side of the housing in the cast part. I might have that backwards (Franklin??). The 60 needs a big socket to remove the brake drum (after pulling the axle). The 10.25 drums seperate from the hub allowing you to leave the axles intact. Sometimes you need to use a BFH to break the drums loose so maybe they took the axles out when they didnt actually have to or you have the older D60

I too have a 460, *semi floater* 10.25 axle.
Mine stick out like that but I do not have to remove the axles to remove the drums.

If the filler is in the rear tin cover it's a Dana.
If the filler is on the front side in the casting it's a Sterling.

Simply put, Dana makes a whole bunch of axles. It could be a Dana 60 or Dana 70. They both have plugs on the rear steel cover. The big three used Dana axles, along with most other vehicle manufacturers at one time or another. GM for example, had the 14 bolt around for years, but used the Dana axle at times on the same truck. It can be a number of reasons they put a Dana 60 in there. It was a 3/4 ton axle, so it could have been swapped in there, or Ford might have put it in from the factory. They had a transition period from the Dana 60 to the 10.25 axle.
As for getting the drum off, I believe there was a time where the Sterling axle also needed the hub pulled to remove the drum (but I could be wrong). The drum might also be rusted onto the hub, or the shoes might need to be backed off. I would try messing with it a little more first, and make sure you have the right axle.

Both rears are (equally?) heavy duty, just the 10.25 is more modern. They switched in 84 or 85 IIRC

Ok so theres even another rear end ford used. Yes my axle hubs stick through the wheel some 6-8in but the fillers on the cover like i stated. Is there a vin code or a rear end code on the door plaque?

Post your VIN code and, ideally, post a pic of the safety certification label on the driver's
side door jamb.
There might also be a tag on the axle held on with one or two of the bolts holding the back
cover on, post those numbers if you have that tag and can read it.
