Seems to be rubbing more on the right passenger side then the left, there is a hint of rubbing on the upper control arms of both sides

when I had my blow out on the right rear side (not that long ago) that would explain away the right side having more rub marks, but the left having some doesn't make any sense

i'm just wondering because I look under my truck about once a month to check for leaks and broken or missing stuff, I may not have noticed this before but it sure looks fresh
the ass end has been feeling a little different for a little while now I exchanged the air pump a couple months ago because I thought maybe it wasn't blowing up the shocks every time, I went and felt the bladders earlier and they were empty, it had been sitting since last night and they filled up good when I started it up and now that it has sat for about an hour they are empty again seems like they should still have some air in them? not sure seems like they held air longer before after sitting parked

I, as well, thought fuel pressure issue at first. Although clogged cat(s) present very similar symptoms as a weak fuel supply, I'm leaning away from clogged cat since you said it "just hit out of no where".

My next guesses are faulty crank sensor or throttle position sensor. Reading a freeze frame for the DTC or even live data would keep you from throwing unnecessary parts at it.
Mine came out of nowhere and then progressively got worse over time.

Just looks like you had a bit of weight in it and cornered a bit hard. There is side-to-side movement which can be increased substantially with the above mentioned factors, so slow down on the corners if you’re worried. Or unload the bundles of *******. Or both.

Wonder if he stuck that new fridge in it.

I jumped up and down on it, rocked it back and forth, wiggled the wheels hard as I could and neither gets it anywhere near rubbing, just strange I could see it happening on the front which is typical if running larger tires but the rear doing it just makes no sense to me

Hey I thought the same thing on my bagged Silverado when I got my new $6000 billet wheels that had a slightly different offset than what I ordered. I pushed and shook and had all kinds of room. Then I went for a drive and promptly scraped both lips on the fenders after going around a couple corners. Believe me, there’s no way you can simulate 4000 lbs ( or whatever our rigs weigh) of force being tossed sideways from g forces.

Edit: if you look at what keeps the suspension centered side to side you’ll see it can move. That’s where (anti) sway bars help but even the biggest can’t stop it completely.
