    Diff fluid leak (axle seal) will cause brake binding too. Seems counter-intuitive, but will definitely lock up the brakes.

    You don't have a bent axle?

    I jacked the truck up and had the wife put it in gear and let the tires spin. No wobble or up and down action at all.

    Update. I took the drums off and had them turned. SLIGHTLY out of round, but not terrible. Still have the issues. This issue is driving me nuts. I've been working on it on and off for 2 years now. Luckily this isnt my daily driver. I'm about to say f it and go with the disc brake upgrade to get rid of these dang drums.

    Just spit-balling more ideas to check... Are the backing plate bolts tight? I can't imagine why they wouldn't be, but it's an easy check. Go front to back, side to side checking your leaf spring bushings, bolts, axle mounting plate, U-bolts, etc.

    My truck did that on my 6 lug and although the backing plate was tight, the part at the bottom of the backing plate where the shoes seated in, which had 2 rivets holding it, were loose. I drilled them out and put bolts in with locktight and it has been fine for a couple years now. You shouldn't be able to easily move your shoes around with all the springs on, except a little on the wheel cylinder side.

    Shit I didn't even think about that one, good find. OP, I'd definitely check this next, and anywhere the shoes mount for tightness.

    How about switching the rear drums around and see if the problem moves to the other side?

    Been there, done that. Backing plates are tight. No grooves on them at all. Bushings all look good, etc.
