Jingle jingle underneath only in 2wd

Did GM purchase your truck back from you because they could not fix the differential  noise or did your truck have other issues as well. Just wondering because my truck has the differential  noise as well along with other issues.

My repurchase was solely based on the differential and drive shaft noise while in 2WD /Jingle.

Ok thank you. Stub shaft,singer,seal have been ordered since October for my truck and stub shaft  has not come in. My GM advisor has not contacted me since October.Gm advisor did tell me in October they did not have a fix for this. I guess my next step is a attorney. I have a log and all recepts of this whole mess. Truck will be a year old in June. Thanks again.

I would go and check out your states lemon law first before getting a lawyer. FYI one of the GM reps “John” assigned to my case was fired from GM around that time frame and I lost communication for awhile also. You may have been dealing with this same guy. Google the BBB auto line and get the case opened with them first. This will cost you nothing and it did work for me. Please feel free to message me here if you need help.

I didn’t win my case yet. I hired a lawyer and they contacted gm several times. Gm never responded so now we are taking them to court. My truck has more issues than just the differential. Check your state laws like others have mentioned.

No. The new 2020 is jingle free.

Not entirely true.  My 2020 has 2260 miles on it.  Built in 8/19.  Picked it up in the beginning of December.  I don't drive it that much, which is to say a few miles a day maybe to the gym and back, no really long trips.  Last week, I was driving around all morning and started hearing a thunking sound.  So while I had the radio off listening to that, I heard the dreaded jingle.  Jumped on here and they symptoms are exactly the same.  Starts around 15-20 miles, only in 2wd, goes away in 4x4.  It does have the SU4 axle.  Anyway, took it in and first they didn't hear it.  Went back the next day while it was warm and took the tech for a ride.  He heard it.  It goes back in Tuesday.  As far as the thunking noise, it sounded like the front but closer inspection showed it was coming from the rear leaf springs.  They said installed "Rear Leaf Spring Insert Replacement and Re-torque u-blots as per bulletin"

I have the clunk just had it in to the dealer and of course they said they couldn't reproduce it. Please keep me posted.

Initially I thought it was from the front.  So did the tech.  Closer inspection and he was able to find it in the back.

I have 2020 LTZ with 6.2 engine that has this front diff. Jingle. Truck has 2500 mi. Started showing up as outside temp got warmer. Goes away in auto mode or 4WD

Yes that's the sound and about the right mileage too. I have 3900 miles on my new truck and so far I have yet to hear anything.

Dealership told me they were going to replace axle on that side. They are going to let me know when parts come in. Is this a fix or just fishing? I have not read all 54 pages related to this issue, just trying to find out what has worked for other people. I would appreciate any advice. Thanks

Unfortunately fishing mostly.  But you have to play the game at first and who knows it might work.
