sounds pretty normal...when turning (on pavement) there is noise from the tires, kinda like skidding...it sounds like its rubbing the wheel well or something but its just the 4wd

 

 

No, i get this rumbling sound when just driving straight down the road while i have Auto 4wd on...

I also have the same issue, I have a 2005 z71. sounds like a grinding noise up front when i put it in auto 4wd (even noisier in4wd). I took it back to the dealer 2 times between 11/21/08 and 12/30/08,the 1st time they tore the t-case apart and said (from the invoice) misaligned case, necessary to replace diff. case and side bearings.

They put it back together and drove it and the noise was still there. They took it apart a 2nd time and found the bearing pattern on the new side bearing races not true. They attempted to shim the case to find that the case is not square causing side bearing wear and gear pattern wear. Replaced case. Replaced ring and pinion and necessary bearings and adjusters (new design).

They reinstalled it in the vehicle and took it for a road test. They said the noise is gone. Not True....I brought it back 2 weeks later (in Dec.) and told them the same thing. They kept it for another 2 weeks and then told me they found that my tires rotate at different lengths. They said the "rotational circumference" was off and that was the noise. Fast foward to today...grinding like crazy.

 

I have a few questions that i was wondering if anyone could answer..

 

1)What color is the gear oil supposed to be?

- before i brought it in the 1st time, i checked the gear oil, it did look like there was grinding going on in there, not clean. The gear oil looked like it should have been a "motor oil color". After they worked on it i checked it this summer and they put a red fluid in there, looked like trans. fluid, it's also leaking out all the seals. when i pulled the top plug, it poured out (they over filled it).

 

2) I was told by the dealer that it was ok to drive in auto 4wd all the time. Is this true???

-I had leased an 04 Tahoe and drove it 4 years in auto 4wd and never had a problem. (I bought the Ava. used )

Mine is making noises as well but even in 2wd but not as much as 4wd and auto. I think it's something in the front differential. I removed the front driveshaft and the sound went away.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      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."
