Your buddy said it was the rear wheels hopping, right? Is it just one side or both sides? If for instance, it's the right side, try swapping the shoes to the other side. If the hop moves, something is wrong with the shoes. It's been 40 or more years since I got something that did that, but you may have contaminated shoes that are grabbing. You can try running a wire brush over the braking surface (wear a dust mask) to scuff them up a bit if both wheels are hopping.

 

yeah but I haven’t had anybody look since you confirm or get a second opinion. Here’s what they look like now, I pulled them off to see if anything looks odd. I put everything back together, and this time I adjusted them just enough to get the drums back on and it still does it.

That is not normal wear on the shoes. Are the ends of the shoes seated properly?

 

i think so? Sorry I have no clue with drums, everything seems to be the way it was, all friction points are lined up with the new shoes. The pins with the springs are straight, To the best of my knowledge they are, maybe the drums are faulty they gave me?

 

That looks like the drums are out of round

 

I also noticed that with my rims back on, one stud seems to be shorter then the others indicating something isn’t right. Of course they’re all the same length and I even checked to see if the stud backed out some but it didn’t. The drum won’t go back anymore, so good possibility it is out of round. My truck shakes very violently, the back bounces and the dash seems like it’s gonna fall off lol

 

Did you clean the grease out of the new drums before you installed them?? They come with a coating that prevents rust.

 

A little trick I use to check drums for out of round, and easier than a dial indicator gauge, is to remove the tire and drum. With the truck on jack stands, flip the drum around. Put a piece of rope around the shoes to keep them from blowing the wheel cylinders apart. Put the truck in neutral and start it. Now slip it into gear. Do NOT push on the brake pedal. Now you can watch the drum and see how it spins. A warped drum or bent axle will be obvious. After you check both sides, shut the truck off and let everything coast to a stop. Pay attention to where the oscillation was and go from there.

Clean the drums of preservative if you haven't. I suspect something isn't seated right and that is why one stud is shorter than the others. It's probably some minor thing that once you correct it, we'll all copy Homer Simpson and slap our heads saying Doh!

 

ill have to try that out, I’m sure i didn’t do something right. Do these things sit correctly easily or do you have to semi hold it together while you work on it? I remember telling myself I need about 8 hands.

 

It can seem like that lol
