Squeaky Suspension

[Landry]

I have a 2019 GMC Sierra Denali with only 14k miles on it.  I took it to the dealership twice and both times they said they that U-bolts of the leaf springs assembly were re-torqued and new real leaf spring inserts were installed.  The squeak goes away for about two days and then comes back.  It sounds like I am driving an 80 year old rocking chair.  Anyone got any advice?

I’m having the same issue with my 2019 Custom Trail Boss.
Did you ever get this resolved?

I am having this issue also.  I had the dealer install the factory 2" lift a few weeks ago, and after I started having a clunking in the rear.  The dealer found a defective leaf spring and ordered a new one under warranty.  It hasn't come in yet and who knows how long it is going to take to get one.
