I’ve owned 7 and it’s my last one as well. GM is ridiculous. They can’t fix anything on these new trucks. They have zero customer service and really don’t even care. I fought for 7 months before they did anything. I just sat in the dealership as they worked on it and told everyone that came in there what issues I was having. Never did get it fixed. Had to file a BBB claim before anyone would acknowledge my issues. It’s a joke.

Question for everyone -

 

My truck has this issue too.  Is anyone aware of long term damage from this?  Wondering if it's a slight rub or actually chipping/wearing away/destroying something in the diff?

 

I'm willing to take a longer term view and make sure GM is aware of my issue but if worse comes to worse in a few years I'll swap the diff out with a junk yard unit myself.  I love the truck otherwise.

It took several months. I tried to get it fixed back in May but was told they couldn't get the parts for a few months. They finally got the parts in yesterday

Any update on if it fixed your issue? If so, how many miles have you out on since the fix?

I just had the "fix" done to my truck yesterday(10/15/2020). New axle shaft, seals and the o-ring. So far so good, but I really haven't had the chance to drive it a good amount of time or distance. And the weather is turning cool/cold here in Wisconsin so it would take longer for the noise to happen. And from other posts I've seen some say the problem went away for a couple hundred miles after the fix, then came back. So I'm going to be listening for it to happen again and will come back here now and again to see how others are dealing with there's and to keep people informed on how mine is doing.

I think if you look up the SU5 Axles don't have this issue, only the SU4s.  I've been doing some research and trying to find out which models have the SU4s or if it just depends on where the truck is made.

Mine was built in Indiana.  If you go look at them and scan the barcode on the B pillar you can see the build code.  I'm going to make sure when I get rid of this one that it doesn't have the SU4 axle in the new one.

Looks like the SU5 has the same noise.

No he didn't have the SU5 axle he has the SU4 which is made by American Axle the SU5 is made by GM. The SU4 is the only axle with this problem.

I'm just going by what he said in his post,  "I have the SU5 on my 2020 and it’s making the same sound.

It could be that it happens but the majority of this issue seems to be isolated to the SU4 axle. GM even calls out only that axle on the PIP document. Not saying it can’t happen to the other but the reporting from everyone who has the issue overwhelmingly points to the SU4.

Just curious if the SU5 axle is only for the single speed transfer case. Most of the issues seem to be either LT or RST.

Anybody with the single speed case have this issue?

I need help, has anyone received a settlement from GM to keep your truck? If so please PM directly as I’m in a hard spot with dealing with them. 
 

Thanks!

Update on my 2020, Dealership has had my truck since last Wednesday. A clip in the front differential was stuck and they couldn't remove the portion they needed to in order to just replace the axle (stub shaft). GM approved a Front Diff replacement. Patiently waiting for my truck to be finished, and hoping that I don't have to go back... Followed the PIP / TSB

So I had that happen to me the first time they attempted the repair. If you don’t have the right tool, the actual GM stub shaft puller, it doesn’t pull evenly and breaks the clip. They pulled the front diff cover and had to use a wedge to pop the shaft out.

Dealership agreed mine has the issue last Wednesday and is ordering the parts to do the "fix".  I'm in the system.

Hey, I just ran into this issue. The tech spent 4 hours making a tool to pull the stub. Broke the clip, and cleaned out the broken pieces in the front diff since GM stated there are none for replacement right now... Just waiting for the front diff to explode now....

Yeah, same thing with mine on the first go around. I don’t think the diff will explode but I do think wear is a concern. The worst thing that you really could have happen in my opinion is premature bearing wear from the shaft walking. Heat is a big factor with getting my front diff to make sounds...

I was just being slightly dramatic haha. Mine made the noises turning left / right and after 4WD disengagement. I will continue to test the "fix" hoping for the best. The dealership didn't really help me out with the work order. I had a three page work order that basically looks like I only had one visit...

      2027 GMC Sierra: Official Discussion

      By Jsdirt · Posted

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.

      Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.

      Disconnecting Battery

      By davester · Posted

      If your connector also has a big lever to get the connector on and off, you don't want to force the lever either way, as it becomes a bigger problem if you bust the lever or the mechanism it works.

      Disconnecting Battery

      By davester · Posted

      It's just useful to disconnect the battery to prevent odd shorting out when unplugging/plugging stuff together.  I also  touch the two cable ends together (after disonnecting) to drain the small amount of stored battery energy in various modules.   I believe the main system where you need to be more concerned with, so you need to do the above and then wait some time, iss when you are working on the air bag system, to prevent inadvertent firing of the air bags.   The in-cab switches are just that, plain switches, it's generally not a problem to swap them in/out.  For my '12, I'll get an error message on the dash if I power up the truck w them unplugged, but that's it (power up= turn the ignition on).   The ITBC located above the spare tire is a computer that manages the trailer brake system.  That is probably more important to have the battery disconnected.  It does have to be programmed to the truck, either before or after it's installed, for it to work.  For my '12, I had a very hard time reinstalling the main connector to it (IDK if yours is the same or not), it turned out the silicon seal was jamming up, preventing it from going on all the way.  I finally got it fully installed by lubing the seal with a bit of dielectric grease, then it slid on and latched in place easily.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      JR ! I just got the truck back from the Dealership today . The technician did a cold remote start on the truck this morning and it made the noise . It was determined that it was a starter issue and replaced it under warranty . Of course   it did not make the sound after a new starter was put in because the truck was not cold . We will we see what happens tomorrow morning when I start the truck cold  . Keep tuned !   Oh I found a video on YouTube of a cold start and it did the same thing your truck and mine do , I will see if I can find it and post it up
