Leaf springs worn out?

Where'd you get all the plastic **** for the leaf packs? I destroyed a couple of the 3 sided things that snap into the holders/mounts/whatever you call the things that keep the leaves aligned.

I think it was sk springs for those.
They aren’t exactly like the factory ones they are a little shorter but nothing else is available
The round puck isolators where from dorman/rock auto

It’s a vibration. Bent wheel is possible and U joints are brand new. Nothing is above suspicion with this truck lol. And it’s mostly when I’m on the highway that I feel it, but I’ll pay real close attention on the way home from work tonight.

In addition to the other ideas, bent/dented/out of balance driveshaft will do it, as can blown out shocks.

Shocks are all brand new (cheapest Oreillys has to offer) on all four corners. I think they’re Gabriel brand? I don’t know. They’re blue lol. Driveshaft I had to replace when an old U-joint took a vacation on my way home one day and ovaled out one of the holes. Found a really clean one at the boneyard, couldn’t find any dents or bruises on it.

A couple months ago I put Gabriel shocks on my wife's Chrysler 300. A month later they were rattling and I swapped them out for KYBs.

Is this when the vibration started?

Hard to say. It was vibrating before I’m fairly sure. My dad and I deduced that the truck got whacked in the passenger side rear before I owned it and that’s why the axle shaft on that side was bent a little. Afterwards the brake pedal pulsated under heavier braking, I assume because the brake show was worn a certain way? Haven’t noticed it doing that in awhile though.

Additionally. I noticed on the way to work today that with a full tank it smooths the vibes out. Still there for sure, but much less pronounced. The bed has always kind of sagged to the driver side too, hadn’t thought of leaf springs until now.

That’s actually where I ended up buying my new ones from. They were the cheapest I could find when all was said and done. I ordered new U-bolts and nuts as well. The truck rides wat better now too, rattles less over bumps and sags less when I sit on the bumper or put weight back there. Overall a great experience with the company, I’d recommend them.
