Popping squeaking noise when going slow over bumps and in reverse

[Greenmachine777]

Still waiting for the parts to come in, not sure if the strike will delay.

I have a 2019 rst z71 with same noise!! Leaf spring was there response.. took it twice already first they lubed the leaf springs and second time place rubber inserts in between leafs springs.. it came back after 500 miles..

Truck goes in tomorrow, hopefully fixes the squeak. Only squeaks when it’s dry

So crazy!

Got it in for the fix on Friday, no more squeak.

I have it bad on my 2019 HC.  Do you have a reference number to the TSB?

I have the same noise in my 2019 AT4 the dealer Freeman Buick GMC has had it in their shop 5 times and cannot get it corrected. I had to tell them what I found here. I'm guessing it is a defect in the new platform. They gave me a new 19 Sierra to drive for a loaner with 14 miles on it and it does the same thing!

Here’s the tsb from when I got the squeak fixed, hasn’t done it since, sorry it’s upside down

WHAT IS CTE?

Coefficient of Thermal Expansion

 

Probably in reference to dissimilar materials (metals).

 

F'ing Engineers....

 

FWIW (for what it's worth), my roof has the same popping sound every so often.

No noise out of the leafs yet. 

Or front diff (jingle)

Does have the recirc whistle

3,000 miles.

Any update? My truck is making a real high pitch squeak in the rear now over quick bumps at slow speeds and can also be heard going over speed bumps. Also noticed the squeak goes away after it’s rains but once it’s dry again it’ll come back. I just torqued my ubolts tonight to about 80 ft-lb. No luck on the squeak. Should I try replacing the leaf spring inserts?

Dealer said it is "bed Shift". No fix and truck is still under warranty.

The leaf spring inserts were causing the clanking. Installed new ones on left rear.

problem solved.
