I had the same issue with my Silverado. Sounded like a loud bottom end rap. Happened driving about 50mph, slowed the truck down, stopped and shut it off. Waited about ten minutes before I started it and never happened again. I would have bet anything that I spun a bearing but will never know. Good luck but not sure you will ever know Sent from my iPhone using Tapatalk

I did the RC 2inch on my 13 and really makes it sit much better. No issues related to ride or handling One hour install Sent from my iPhone using Tapatalk

I did not have one on prior three trucks but my 13 I bought used had one and I love it. Keep tools and misc stuff without having to worry about it. Good access and it comes off in five minutes. I got the tri fold that just clamps on at the front and rear. Easy off if I need to. Give it a shot Sent from my iPhone using Tapatalk

Almost sounds like the flywheel hitting the cover. Could be loose or cracked. Under load it goes out of round and hits the flywheel cover. Easy enough to check. Out a hand on the cover and run up the rpm’s Sent from my iPhone using Tapatalk

Flywheel related maybe. At idle there is not load but under load whatever it is if increasing speed Sent from my iPhone using Tapatalk

Fuel pump? Not much else under there that draws power and would sound like that Sent from my iPhone using Tapatalk

X2 on diablo. Shut off Afm and top speed limiter. Canned tune changes shift points. No lag on acceleration and easy to use on my 13 Silverado Sent from my iPhone using Tapatalk

I am told by a GM employee the issue is "resolved " for 2017 models. I asked what was fixed and was told the fix was dampening of every drive and suspension component so it is not fixed but more buried across dampening components. Not looking for an argument-just sharing info that was shared at the dealer level by a GM engineer brought in site to address issues in 2016 models that were coming back with recurring issue Sent from my iPhone using Tapatalk

My brothers dealership actually mentioned trying that. I will ask him what the outcome was Sent from my iPhone using Tapatalk

RT I do appreciate the level of detail and effort you have put in and sharing the information, every little bit helps and unfortunately some people don't understand the value of a person's knowledge that actually creates shit out of nothing. keep it coming Sent from my iPhone using Tapatalk

Chevy is trying to minimize their exposure on this, my suggestion would be to bring it back repeatedly and not let them off the hook until it is repaired. They are fighting buy backs at this point because the more trucks they buy back the bigger the problem is that they have to acknowledge and they have one most of them in arbitration. Their claim is that it is excluded from the warranty as it is a minor in normal vibration that occurs in trucks typically. The more visits and complaints that you can document the bed of your case but if you look through the thread which may take you days you will see that while some repairs have made it better there is not anyone fix that anyone can point to that completely fixes the problem, some fix the problem for a short period while others don't fix it at all. The key is to make sure that it is going back in for the same problem and at some point you want to find out who the General Motors zone manager is and start going up the food chain a little bit with your complaints but I understand they will fight it all the way. My brothers dealership had a GM engineer on site with a truck for a week trying to figure out the problem and they came to no conclusion in terms of what the cause was, they really don't know what it is so they are just throwing parts at this, tires, driveshafts, wheels, rear ends etc. Good luck, based on everything I had read I would say take your losses and jump into another brand or by an older product Sent from my iPhone using Tapatalk

Loyal Silverado owner since 93. Just bought a one owner 2013 short bed reg cab Z71 with 26k miles from an older prior owner. The price was below book and pretty sure it will be my last GM after this screwing they are laying on owners. I could have had a new Silverado with huge rebates as you all know but I don't trust them or their new trucks and yes...this will cost them over time Selling my 06 ext cab if anyone is interested.

You are 100% right on the ram having potential for rust issues, that was a big reason I got rid of my 2014, the way the inner fender well on the bed is designed is just a hotbed for debris and moisture. I actually looked at a 2013 short bed and might be doing that deal, it is a one owner Z 71 package leather, tonneau cover, definitely looks like it was owned by an older gentleman. Feel more comfortable buying it when you're older truck with low miles, 26,000 versus buying a 2014 which could have potential for the shake. I have a 2006 extended cab Silverado with 140k on it but have some issues that are starting to creep which are going to be expensive, should still be able to get $9000 out of that and put it towards something else. With the ram, the risk of rust is far greater than on a GM product, my 2006 has zero rust, not sure why because I live in the Northeast but I always kept it clean during the winter times. Thanks for responding, this is a great thread and a great group of people (generally) Sent from my iPhone using Tapatalk

I had a 14 for a year , no issues at least nothing structural like the GM problem. Interested to hear your opinion on this I think any new vehicle comes with issues-it's a matter of accepting those which can be fixed and this Silverado issue is sill an unknown so prefer to avoid it.
