Anyone got a good idea on how to get the drum off? It's stuck to the axel, not the bands. Can I pull the axel with the drum on, making it easier to work on with a BFH..

And, does this look like the correct replacement? Seems different than the original :confused: Looks like the contact area for the bands are wider on the original, but it's enough space for 2 1/2" bands in the replacements.. Can't be sure before I get the old ones of, but if they are most definit wrong I can leave the old ones on until I get the right parts..

I had a 30 ton puller and worked on mine for hours. Then an old timer tells me " Jack it up in back and put it in reverse. When the wheels are spinning pretty good drop it in drive and WHAM". I look in the rearview and the drums were half way off. The only way I do it now. Block and chock the truck properly first.
 
The 13" drums and shoes come in 2 different widths - 2.5" and 3.5" .
The 11 5/32" drums come in 2.75" shoes.

As for getting it off, a hammer and force seem to work good for me.
 
They came off, after some work with a sledgehammer. The shoes were 2.5" wide, while the drums were for 3.5". So the replacement drums did fit after all. :thumbsup:

I am assuming here based on your first post that you are saying that the old one you took off were wider. When I did mine I discovered the same issue, the thing is that the appropriate drums with the wider band for the FF axle have a slightly larger pilot bore so will not work on the semi-floaters. Intrigued by this I did some research and came across a tech article that discusses rear drum noise on the SF axle being cured by GM with a 3.5" drum that fits the SF axle. This then explained why I had a 3.5" size that fitted my axle. My guess is that GM started fitting them at the factory. Running aftermarket drums now with only the 2.5" width and no noise as yet.

I'm not sure I understand this suggestion. Are you saying the wheels are still bolted on the rears? You get the rears spinning in reverse and then suddenly throw it into drive? Wouldn't this damage the tranny?

No wheels on at the time, Rob. Tranny is a lot tougher than that. I'm not saying I spun the axle at 100 mph either. Just enough to let the flywheel effect break the drum loose from the axle flange.
