    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Grabbed some Mobil 1 5w30 High Mileage Extended Performance, AC Delco UPF48R oil filter, AC Delco A3181C air filter, and a Fel-Pro 70820 drain plug gasket for next oil change.

    Vigor air ride shocks?

    Just following-up with you to see how those Vigor Air Shocks are holding-up? Curious how many miles you have put on them, the type of terrain driven, as well as ride quality?

    Denali AWD driving off road.

    You’d need to make the GMT 900 about 8”-10” narrower! Black Bear is pretty tight and hairy. So much shelf road.

    Denali AWD driving off road.

    Thanks, not planning on the Alpine Loop. I fully appreciate the benefits of a 2-speed transfer case and that is why I have been asking so many questions regarding the Denali (Escalade) AWD real-world capabilities. I really do not feel like buying a new (used) 4WD with low range when my Denali is...

    Denali AWD driving off road.

    Nothing too hardcore, Ophir Pass and would like to do Imogene Pass but not sure the Denali is up to it. Might do some testing in Uwharrie National Forest on the easy-moderate sections.

    Denali AWD driving off road.

    Do you drive the Denali up and over many mountain passes? Planning to take mine to Colorado this summer and a bit concerned about not having the low range transfer case available.

    Ohh, that’s what I get for making an ass-umption!

    Anyone Off-Road their Yukon Denali with OEM suspension?

    Thanks, I contacted him (MrPeterClark). He sells GMT900 bumpers, roof racks, etc as well. He runs the Icon suspension on 33", though I think he's going up to 35".

    Anyone Off-Road their Yukon Denali with OEM suspension?

    Very informative, thanks! The last pass I did in Colorado was Imogene from Telluride to Ouray in a 2020 Defender 110 S; of course used low range extensively. I can't see my Denali doing Imogene. I was a bit concerned about the Denali doing Ophir (even though it's easy) because I understand most...

    Denali Duramax: Expectation vs. Reality

    Yup, you have a 2-speed transfer case with 4WD Hi and Low Range. Thanks for posting the picture!

    Anyone Off-Road their Yukon Denali with OEM suspension?

    Thanks, definitely realize the limitation of stock ride height clearances. Really curious how especially the rear Autoride air shocks due with rough off-roading in terms of articulation and potential air shock blow-outs. Have found very few resources of people actually off-roading their Denalis...

    Anyone Off-Road their Yukon Denali with OEM suspension?

    Have been seriously considering Fox 2.5, 2.0 and Icon suspension setups to replace my OEM Autoride system (front/rear). I have 177k+ miles on the OEM suspension so I am considering either changing it out with Fox maybe Icon or just replacing OEM Autoride Z55 on my 2011 Yukon Denali AWD. 99.5%...

    Tire Pressure Sensor 09 Yukon

    Deflate tire removing valve stem Schrader, use a piece of wood to break the bead by stepping on wood with tire flat on ground. Unscrew TPMS and Valve Stem, replace and secure. Reinstall Schrader valve and re-inflate tire. Lots of guys do it on YouTube, looks like a PITA to me. Tire shop can...

    Randeez 2012 Budget Yukon Denali Build (stick on hood scoops galore)

    Very nice, wish I had 4.10’s as well. Might help with the lack of low range 4WD.

    Denali Duramax: Expectation vs. Reality

    If you’re doing lots of highway miles, especially towing, the Duramax makes great sense. If you drive mostly in-town doing stop-and-go, this modern direct injected turbo diesel will never be able to regen its DPF as often as it needs to. These factors along with more points of failure: DPF...

    SD Card is Not Functioning Correctly Message

    Please forgive me if this is a stupid question, but could it be the SD card needs to be formatted to ExFat, or some other specific format?

    Steering wheel controls cheap Android head unit.

    Pretty sure this is not what you are looking for, however, it's the best idea I could come with. I would probably ask a professional installer at Best Buy or a Tint Shop. If there is a simple component, they will probably sell it to you. If it involves running some new wires through the BCM...

    Are you changing the gearing in both diffs? What's the new gearing going to be?

    Denali Duramax: Expectation vs. Reality

    Does your new Duramax Denali have a low-range transfer case or is it single speed (high) AWD only?

    Ground issue? Help!

    Sorry to hear about your experience. I think it comes down to locating, inspecting, possibly cleaning your ground connections first, then really checking the wiring as well as the 12v battery lugs and wires. Wires and especially connections get oxidized and brittle. You can often just clean, and...

    Cabin Air Filter Retrofit

    Similar experience when I did it except I used a Leatherman serrated blade and file. I did a very ugly hack job to be sure.
