Anyone wanna take a guess what this binding noise is?

Dealer told me they can't give me a loaner until they find a drivability issue so I'm trying to do some troubleshooting myself before I figure out how to get to work while they diagnose...car is in 2wd, flat surface just crawling forward in drive and it hear this echoing off my driveway walls.

 

I have another susp sound I can only hear in the cabin over extremely slow bumps like when I drive on grass very slowly sounds like a ball joint almost, not a loud pop / knock more like a bobbling noise.

Are you applying the brakes? I had that same noise ended up being the rear pads.

Sounds like the rear leafs are creaking. They need inner tube rubber placed in between the leafs, and some high quality synthetic grease applied to them to quiet them down.

This can be a possibility

This seems to be more likely, I had the same issue, applied grease and it still squeaks a lot tho

i agree i did the same and it went for good

My 2013 did this a couple of years ago, when the truck had around 20k miles. When I performed the leaf spring lube, the noise was gone for good.

I recommend simple test..

Spray water on completete rear leaf spring assembly to inlcude shock mounts, then do same test.

If noise has gone,, chances are its time for full leaf and pad lubing with good marine / water resitant lube.

 

If no change,, try water spray on front suspension as to isolate front from rear noise.

 

Also check tourqe specs on all components to insure this is not part of problem..
