I was on the Outer Banks of NC the other day just riding down the beach when I decided to go have some fun and get into some soft deep sand. I was riding along, playing in the sand when I got into some REALLY deep sand and had to turn the wheel all the way to the right to get better traction. When I turned the wheel the truck kinda shuddered and the front end made a terribly loud pop sound. I stopped immediately anf straightened the wheel and backed right out of it. It hasnt done it since, but then again I havent repeated the same thing either. Im pretty sure that the shudder is from the locker, but I have never heard a pop like that before. Everything still works great, it just worries me that I have never heard that in any other truck that I have ever owned. Anybody know whats going on?

 

By the way, I was in 4-hi and not really raising hell, keeping it under 15 mph.

I realize this is not your case but last time that happened to me was on my 91 1/2 ton. I was wheelin' some pretty tough stuff and when I got out to inspect the noise...I had a broken front half-shaft! Anyway, maybe it was the inner CV binding up...I really don't know, but turning full lock and wheeling where you are getting good articulation puts those half-shafts in angles that sometimes they don't like. After busting 4 axles in less than a year, that is why I bought my HD, in hopes that the IFS components would be a little stouter/stronger. Anyway...good luck!

Mines got a decent POP certain times when I'm steering. It was doing it before my lift too. I think it might be my hub because I just found out that it's going bad. On stock trucks there is a tsb out there for grinding off the coating on one of the sub frames or something.

 

It's kinda a mystery! :crackup:

There is a TSB out about adding a thick flat washer to the front crossmember bolts.

I could only fit one per side, font side and back side due to the close proximity of the bolt holes. It worked for me. No more popping. :eek:

I get a popping sound under one the left front side when I turn really sharply (like when backing up) and then, when the truck cools down, I get this loud CLANG from the same area. I plan on taking it to the dealership next week so I'll let you know what they say it is.

Do you happen to know the number for that tech bulletin? Or the title so I can look it up?

I'd also be interested in this TSB #. :D

Yup, mine too. Usually when I'm pulling into my driveway, turned sharp right and the pop seems to be coming from the drivers side.

 

If anyone can post up the TSB that would be great. I didn't see anything in the "Ask the GM Expert" forum.

 

Thanks,

AJ

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
