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

    These are the ones I bought, and they do have a lifetime warranty. I've gotten to the point though where it's about an hour and a half per side to get these done, so not a big deal if I have to replace them in 5 years. https://www.rockauto.com/en/moreinfo.php?pk=6117468&cc=1502531&pt=10401&jsn=550

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

    Well, shit. I did a bunch of reading and there were a ton of positive reviews, so I rolled the dice. I put a mix of Duralast uppers and Moog lowers on my '07 a few years ago because I needed the parts same day and that's all the local stores had. The rubber boots on the lowers are cracked and...

    Chevrolet Suburban 3500 Questions

    Like you, I think 16/23 is fantasy. I've seen 20 on a 150 mile highway trip with just me on board.

    Chevrolet Suburban 3500 Questions

    Well, it’s not a direct comparison to what you’re asking, but I used to pull the same camper with a 2012 Yukon XL with a 6.2 L. With that, I’d get about 7.5 on average towing, and with the suburban 3500 I’m getting about 8.3.

    Gotta do a Rebuild, Gonna Upgrade Too

    I don't have any direct experience with the LT motors, but on the GenIV LS 6.2 in my 2012 (L94), I went with a 3-bolt cam (no VVT) and am thrilled with it. VVT on the LS engines was only good for maybe 15hp, which is easily made up for with a bigger "truck cam". Maybe someone who's upgraded...

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

    Both shocks look good with no leaks and have been performing well, so I'm just going to replace the control arms and outer tie rod ends. Already did the sway bar links in 2021 and they still look good. Went with Mevotech Supreme parts. I have a lifetime alignment on this rig at Firestone so I'll...

    AFM Lifter Stuck in Lifter Bore

    Seriously a can of worms. But, it will be better than new after a rebuild.

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

    Update: just had my father-in-law come out and put a prybar under the front tire while I looked at the ball joint, and there’s just a tiniest little bit of upward movement in the joint. But no play is permissible, unfortunately, so I will replace them. Took the 2012 to the shop today for state...

    L83 to l96 swap completed finally

    I have no doubt. Very, very impressive work.

    Another P0300

    This sucks, man. I'm sorry. I responded to your question on the new thread but will share here also for the listening audience. If that lifter is really stuck in there, the motor may need to come out and taken to a machine shop to get the thing out and the lifter bore sleeved. If you can get...

    AFM Lifter Stuck in Lifter Bore

    Is the cam still in the block? If not, perhaps you can drive it out from the top. Some machine shops have the ability to put a sleeve in the lifter bore to repair it. Those bores do need to be in spec to keep the lifter firmly in place and to retain oil pressure. But the engine will need to come...

    L83 to l96 swap completed finally

    Way to go and I admire your courage to just set out on the journey, come what may. And you got it done! I have the L96 in a 2018 Suburban 3500 HD, and it's a beast. Smooooooth runner, too. With 4.10 gears it can really haul a camper. :)

    Do you mean the literal username admin, or will a user account with full administrator permissions still work okay?

    2019 Yukon HUD is Intermittant

    Yes, this is correct. This gent shows it in his video:

    Service message

    Found a little more specific info for both codes. The U1518-00 looks to be a problem with the comms link to the HUD, which makes sense because it's not installed. So I'll eventually fix that one when I do the install. The B101E-48 code has a bunch of different possibilities, but no fixes except...

    Your experience with this generation and your perspective are helpful - thank you. Yeah, it may well be related to the cluster but what I can't figure is if that's the case, why it took so long to manifest. Anyway, I'll get the fob batteries changed and let you know if that changes anything.

    Service message

    It does not, but the cluster is configured for one and I have the hardware for when I get up the gumption to install it. Weird on the fob relearn. It was getting a low battery error on the fob before that, so I'll replace the fob batteries as a next step.

    0W-20 to 0W-40?

    I think the factory spec oil is 0W-20, yes? On the earlier 6.2's like mine it was 5w-30 and as far as I know the main, rod and cam bearing clearance specs haven't changed between the LS and LT motors. Some guys here, including me, run 5W-40 Euro-spec oil in their 6.2's. I changed to it on the...

    2019 Yukon HUD is Intermittant

    Nope - not hard at all. A sharp strike with the palm of your hand to the underside of the visor over the cluster should pop it up and loose. The HUD unit is screwed into the panel beneath the visor and behind the cluster. If you want to get to the HUD controls, that panel comes off easily as well.

    I have an Autel bluetooth scanner dongle, and it uses a pretty rich Autel app that allows all kinds of scans and service functions on GM vehicles. It recognizes the VIN and the L96 engine, but it can't connect with the steering computer to check for codes. It's fine with all other modules...

    Thanks Wes. The 3500 has hydraulic reciprocating ball power steering. It's old school :) But I will check the grounds for everything this afternoon.

    Going to engage in a little thread Necro here because it’s the only thread I found on this particular message. I have a 2018 suburban 3500 HD, and I’m not sure if it’s related or not but a few weeks ago I swapped the factory cluster for a Denali cluster that was programmed by White automotive...

    Towing 33’ trailer with 2018 Yukon with Tow package.

    28 is a really nice size also. The main reason my wife wants the 30 is because of the slide out pantry. Lol. Are you happy with the overall living space and storage in your airstream? Do you do any Boondocking with it?What do you like most about it?

    Are Yukons/Tahoes reliable?

    Better yet, get yourself a Blackbear tune and they'll turn off the AFM permanently, and also clean up the compromises in the factory tune for the engine and transmission, and wake the whole truck up for you. I'm thrilled with their work, so I've had them tune all 3 of mine (2 6.2's and a 6.0)...
