Popping sound from rear end

[HondaHawkGT]

I bought my 2015 Denali Crew cab just two weeks ago and mine is doing the very same - one metal on metal pop when I first accelerate and then again when I brake or decelerate. Dealer swapped the drive shaft and did not correct it - they too called GM and opened a "ticket" to see if the know of a solution. May call them and schedule a time to swap the leaf springs based on feedback here.

 

I GM monitoring this site? Surely they have run into this somewhere and have found the cause hence have a solution ... fix by trial and error has to be costly and frustrating for customers and jeopardize their loyalty.

I picked my truck up after 2 weeks & it still makes the popping sound...They are assigning an engineer direct from GMC to my truck in the next week or so, so I'll drop it back off for round 3

Check your spare tire. Click the link I posted. Don't just push on the tire with your hand. Instead, kick it and you'll hear the popping metallic noise. The cable seems to stretch slightly and allows the spare tire to shift and make noise. I even tightened it up and it still makes noise.

If that is the case that's unacceptable to me to hear that noise on a mid 40K truck

I just gave my spare a few kicks and didn't hear anything ......

I had this noise as well on my '14.....replacing the leaf springs fixed the problem on mine

How did you get the dealership to replace the leaf springs? I've been battling with the dealership and GMcustomer service for months now. They just tell me that the leaf springs will have to be greased regularly, about every oil change. BUT... a day or two after they grease them, it sounds the same if not worse.

You need to flip out or call corporate.......I am on the brink of that right now

My 2015 silverado LT shaker after 75 mph, but the dealership patched a tire and said it might not hold. Doesn't sound too safe to me.

But at first it sounded like a hollow krink noise on uneven driveways or dirt roads. The service manager said right away that it was the leaf springs.They Greased them and torqued everything to factory specs. Now that noise is still there, but every time i stop and go and turn, even when someone gets in or out of the truck you can hear the leaf springs. It is super annoying and embarrassing. You purchase a 40k+ truck brand new and it shouldn't make this noise. The GM customer support on this forum is trying to help me but it has been months of dealing with them and the dealership, just to hear them say it will have to be serviced (greased) regularly. Even though it only goes away for a day or so. Any other members have different solutions? Oh, you can also grab the tire and rock the truck back and forwards and hear it that way as well. Sorry about the rant, I'm just f**king pissed and want this issue resolved.

I said the same thing.....It's a new 40+K truck that sounds like clunkers I had as a teenager. .....unacceptable to me

Yeah. And all they can say is "It just needs to be greased regularly if not more" BS! It is warrantied and I bet money that if i test drive a brand new one on the lot that it will not make that noise. That is not part of maintenance... Like i said, the GM customer member on here is trying "trying" to help me, but i am at the point that i probably will contact GM directly. If anything give our gift vouchers for the trouble so that I could buy a lift kit and fix the problem myself. Everyone is happy.

Yeah that is not regular maintenance .... its got to be fixed not masked

GM Customer Service representative on here just told me that they contacted the dealership and there is nothing they can do about the noise. WHY THE F**K NOT? How about GM gets the dealership to fix my brand new truck! Not just grease it, but fix the issue with new parts? I'm about to contact GM on the phone. I will record the noise and try to post it up later this weekend.
