Jingle jingle underneath only in 2wd

z71 man · May 17, 2019

Picked up my 2019 Silverado today , already had the front differential replaced and that did not solve the jingle .Field engineer came to the dealership and drove my truck , heard the noise and confirmed it is the drivers side stub shaft coming in contact with the center pin inside the differential, said GM is currently working on a solution for this problem, as of right now there is no fix for it. Said it was safe to drive it this way! They will contact me when there is a repair is available. Could possibly be 2 or 3 months

I get that it's a first model year but these trucks should not be let out of the factory like this. It really is inexcusable. Hard to enjoy your new truck when you have a major defect right out of the hole.

Just bite the bullet and dump it! Chevy screwed me and the rest of you. Today I was buying some beers and about to leave and the Raptor started raising hell beeping and such. There was a car a good 30 feet coming towards me. The system actually works! If it were the Chevy, they would have to be directly behind you before it told you. It reminds me of the old Nissan’s they called Datsun. They got the message years ago because very few bought the crap

Just curious- did they elaborate as to why it goes away in 4wd? I guess the torque presses the shaft out a bit...

Unfortunately it happens all the time with all manufacturers. Half of all 3rd gen Tacomas have a howling rear diff that Toyota hasn't done much to address. At this point they basically deny it's an issue. Their front diffs have had vibration issues for years and they haven't done anything to address the issue. Ford has had a garbage 4WD system ever since they went to their IWE front hubs. I know a guy with a 2016 F-150 that's had his 4WD grind up IWE's several times. "Chevy sad" is going to to find out pretty quickly how much Raptors like to eat IWE's.

Yes I noticed as the weather is getting warmer the sound had gotten louder too.

iWE’s, most fail at 70-100k miles. I take that any-day over what I just went thru. I feel for ya’all, I loved that truck. I made a mistake, self inflicted pain, of buying a early version and a GM project. They are great looking and that 6.2 with the 10 speed using the 3.42 gears was awesome. But the 16k in options was a joke cause none of the shit worked. I hope you guys get the stuff fixed. Chevy lost a customer who buys every year.

Haha every 70-100k? Maybe back before Ford went all-in on turbocharged engines and cheapened up the vacuum system that IWE's require to function. The IWE's in the 2015+ F-150's have had major problems that continues on today. I know guys that have had the IWE's in their brand new F-150 fail half a dozen times in less than 2 years. Ford still hasn't done anything about it. Didn't really expect them to, though. I mean, they STILL have cam phaser and timing chain problems after 15+ years of designing DOHC engines....

Look up the facts, not from forums. Just like here. We all bitch about our trucks. I bet most of the new trucks are better than the early builds or at least I hope so.

I am sorry guys, just hate that Chevy is not stepping up. I would have been happy with the Silverado, if they actually fixed things. Old farts like me expect stuff to work like it used to be before we hurt everyone’s feelings.

Please can we not turn this thread into a shitshow?

Keep on topic and let's get to the bottom of this noise and the correct fix. Looks like we are getting close here.

Thanks.

Thanks, your right! Back on topic. I once had F150 that had nearly all the symptoms. It made a rattling noise and vibrated a small bit about 42 mph. In 4x4 mode all was all well quite and smooth. First they rebuilt the transfer case because they said the driveline was spinning to fast, then the revered hubs, finally the found the ring and piñon were shot in the front. In your case, I wondering if the front driveline is spinning in 2 wheel drive. It should be. If not, maybe it’s just sitting there rattling. There are solenoids that activate your synchronizing clutches in the transfer case.

I dunno but if you watched the short video link I posted earlier you can see the play in the drivers side half shaft in and out. I’m 99% certain that’s the noise. For whatever reason in 4wd it must take up that play and make the connection right.

The passenger side shaft is tight in there.

Well the dealer replaced my front differential and the noise is still as loud or louder. Heading back to the service department again on Monday morning. Hoping with this new information from this forum they will at least check into it. Thanks for all that are posting and helping find where the defect is.
