This is what I used on my 2016 leaf spring noise. It stayed on there forever and got rid of the noise. Maybe this would help: https://www.amazon.com/Super-Lube-11016-Aerosols-Dri-Film/dp/B07DCDYM26

I have been running it quite a bit after I saw this post. It seems to get better fuel mileage and is more responsive.

Moe before you order look up the rancho# for the rears for your 2019. It shows to be an RS99198 and the Bilstein equivalent is a 24-186742. Those also show to fit the 99-06 trucks. Bilstein hasnt done much to cross them or even have a listing for a 2019. I am thinking about ordering these soon.

Those look like the GM steps I just installed. I got them from summit for $192. Dealer wanted $400. https://www.summitracing.com/parts/lnd-24010562/

See if this helps:

On my 2016 I had a noise that sounded similar and I stuffed rags all over and taped stuff down and messed with the door plugs. One day I raised up the 40 part of the rear seat and the sound went away. My rattle was the plastic that holds the seat cover on. I taped it up and have not had a rattle since. I hope this helps someone out there!

We had a 2010 W/T and the a/c was freezing up and not cooling after about 5 minutes. It turned out to be the evaporator temp sensor. We had to take it to the dealer as it involved dropping the dash to get to the sensor.

Not sure but it looks like this module GSR-GM03 will add XM to your system if you have factory usb.. https://www.vaistech.com/product/gsr-gm03-w-tuner-kit/ Same thing used to be available at the dealer but who knows these days.......

You have to get the chrome pieces off to pry the rest apart. I destroyed the chrome pieces trying to get them off. Here is a pic of the parts: https://www.ebay.com/itm/Keyless-Entry-Remote-Car-Key-Fob-Shell-Case-Cover-for-M3N-32337100-4b-Chrome/292260183861?epid=2265359433&hash=item440c107f35:g:Sd8AAOSwXLpZwBB5:sc:USPSFirstClass!70360!US!-1&vxp=mtr

You probably pinched the wiring in the harness and shorted it. That is what happened to mine. I was able to fix the harness and route in better after the repair.

Here are the instructions: https://echomaster.com/index.php?controller=attachment&id_attachment=1438 Yes just the radio bezel area and you have to plug in a wire at the MVI behind the glovebox. I did not remove my grill as I just ran the wire and mounted the camera at the M in GMC. I have a Denali grill. If you can do any basic work its easy. I am not a mechanic by any means but I will try a DIY project here and there.

Was pretty easy. Hardest part was running the camera wire through the firewall. You dont have to add power or anything as it hooks up to the factory radio and works from there. Comes with everything you need to install.

Does not fit in the spot but if you get it in there level on the bezel it charges fine! No pics of course.
