Jingle jingle underneath only in 2wd

AnthonyH · August 26, 2021

Dang, that sucks. I absolutely love the truck, but this is frustrating. I can't believe it but ill have to switch brands soon if theres no fix. Too expensive of a ride to sound like a dump truck.

I’ve heard it on my 2020 Trail Boss but only once. I’ve got the SU4 axle.

Does anyone with a leveling kit have the jingle? Thinking about leveling to see if that will stop it it wit the different cv axle angles

I hear it on my 2019 Sierra if I drive far enough. Local trips it doesn't to it.

Have 5k~ on my repair and no issues since. If it comes back I will throw the SU5 assembly in.

What did they replace on yours?

I drive 55 miles each way and I've been running Auto4wd for several months with no real noticeable loss in mpg. I can tell you, in my humble opinion, it's a lot louder than a "jingle" in my truck. It's a loud, ear piercing squeal. Pretty embarrassing driving a new truck down the road, especially when you see all the dogs running for the hills.

I'll be running this way until they find a fix.

Here's a link to another thread on Auto4wd. One guy says no reason to use it, but I beg to differ. : )

I'm assuming the answer is no, but just keeping the thread running regardless... any one heard anything new from "GM Engineering" I'm sure they're hard at work doing engineering stuff.

I called today and booked an appointment for the leaf spring PIP and asked. He said no fix yet.

I called the executive again and she was going to call engineering again but did not call me back yet. As far as I know nothing has changed. Here is her contact information.

Terry, any reply from the Exec Liaison?

I just had my 2021 5.3L 4WD RST Z71 in to the dealer and they pulled up PIP5653 to explain the issue and there is nothing they can do. I understand that the dealership can't do anything if GM Engineering doesn't provide a fix but even they were shocked to learn that this has been under investigation for a solution since April-2019.

After 2.5 years without a solution, I fear that GM won't ever fix this. If it is purely related to an AAM supplied axle then it would take less than a month to dimension out the AAM axle with comparison to "good" GM axle to find out the difference points. Then another 3-4 months to design a solution. Then another 6-8 weeks to make a prototype fix to test as resolving. Then make the durability testing which eats most of the time with a worst case scenario of 12 months to do. That puts us at a mass produced solution about a year ago...

Anyone working on a class action suit for this issue? Seems to be a good candidate since there is a specific RPO code that designates 1 of 2 available axles without any resolution.

I just received a email back and she says this " As we discussed, I reached out to our team of Engineers concerning the ringing/chirping noise. I was advised it is still under engineering investigation and there is not an update at this time."
