When pulling drums on full floater, what all should I replace?

[MikeC]

The hub and drum are just friction fit together with a little rust for glue

One of mine came off with a 3lb persuader, the other took a little heat and the same hammer, oops I mean gentle drum removal device.

As a reminder, the 3/4 ton diesels take 1 ton parts in the rear. What this means is you need the 3 1/2" wide shoes, not the 2 1/2" wide ones.

Some parts counters seem to be aware but others aren't.

yep torch will do it,what i've found is as you heat it will pop when it does its ready.

Perhaps we should try to find out if there's a rule on what GM did with these trucks. I am certain that on my '97 the hub/drum was an assembly which was connected by the lug studs (which were pressed through both the hub and drum) and that there is no way to get the drums off without removing the axle and hub. I am running rear discs now... they're also attached to the hubs by the studs which are pressed through both. Anyone know why we all seem to have different results?

The 14 bolt FF in my 1984 takes a socket similar to the older front hub sockets (with 4 prongs), but the socket I needed has 6 prongs. I transplanted this axle from a 1979 Chevy though... and GM may have changed what it takes over the years.

Quack,

I'm not sure because my tools are at home, but I think the socket I used was six point. I do know that if it had rounded pins instead of the square teeth it would have been easier to use. It now has rounded pins

I think mine just might come off when I put the torch to 'em. I can tell that the studs are not press fit through the holes in the drum because the holes in the drum are slightly larger than the studs.

I'm excited now; I get to save some labor AND play with fire! Thanks for everyone's input. I'll report back once I get the job done.

Good Day!

Guess I pulled the axles for no reason. Looks like I paid the moron tax again.

Blessings!

GM did the 14 bolt FF both ways, some you have to pull the axles and hubs/drum and others the drum slides off the hub w/o removal of the axle. If you have to pull the axles then the lugs are pressed in and hold the drum to the hub. I'm sure w/research there is a break down on the yrs each were used. On my 92 I have to pull the axles.
