I can't remove the drum on a 69 1/2T. Is there something I am not doing right. I don't see any bolt hole I can use to back the drum off. This is my first time changing chevy drums. How do I get these suckers off?

Thanks

Rick

Front or rear? Front is held on with the hub (unless someone has already ground the rivets holding them together off.)

Either on should have a hole in the bottom of the backing plate to use a screwdriver to back off the adjuster.

front...i just realized that I need to remove the hub nut in order to pull the front drums off. ........Thanks....Do the rear drums slide off after i losen the adjuster?

Yes, rears should come off, sometimes they need a little persuasion. On the fronts once you get them off grind off the rivets that hold them to the hub, it will make the job much easier next time.

I've never seen a 70 and older 1/2 ton with slots in the backing plates. They were always on the drum it's self. However, the replacements don't have the hole and you have to grind it out yourself.

Ya,, what longhorn said. I bought the cheaper drums that don't have adjuster holes in them. If a person drilled holes in them whould that not throw them out of ballance? Unless you drilled holes on 2 sides of the drum to balance it out? Maybe it's a sign that I should just convert to disks?

I never noticed a ballance issue when I did that to mine, and I know I had it to at least 105 MPH.
