    Anyone Have Links or Part Numbers to Transfer Case Plugs on 12' Yukon XL Denali?

    Finally got it! I went to Advance Auto one more time and found a 1/2" brass plug. The threads lined up perfectly and I even confirmed with caliper. I brought them back, put some thread sealant on them, topped off fluids, tightened with 7/8 SAE socket, and torqued to 35 ft lbs (not sure if that...

    Anyone Have Links or Part Numbers to Transfer Case Plugs on 12' Yukon XL Denali?

    The plot thickens. Got these ordered a week ago, and picked up from the dealer today, only to notice that they were about a third the size that they need to be. Before ordering, the GM parts department confirmed that that was the right part for my transfer case, so based on what the numbers say...

    Anyone Have Links or Part Numbers to Transfer Case Plugs on 12' Yukon XL Denali?

    I recently changed the fluids in the transfer case and noticed that the plugs are pretty mangled, and I don't want to risk stripping them next time. I ordered these two from Amazon to replace the fill and drain plugs but even though they should fit according to Amazon and Rock Auto, they aren't...

    2012 Yukon XL - 6.2L Engine Rebuild/Swap & Addressing AFM/DOD

    Apologies in advance for yet another AFM/DOD post to muddy the forum waters, but I have the 6.2L with 180k. It has a collapsed lifter and low oil pressure (leaking from oil pump). It may be conjecture for me to assume that it is AFM related, but I do hear that this type of problem is a common...

    2012 Yukon XL (Denali) - Best way to Touch Up Small Dings and Scratches

    This is a 2012 Yukon XL Denali that has had a few previous owners, and with that, dings amd scratches. Those don't bother me at all from a cosmetic level, but what does bother me is the potential of rusting. There are a couple of areas that I can see where the paint has chipped off, and I can...

    XTOOL D7 Not Giving Option to "Add a Key" for 2012 Yukon XL

    Amazing! That worked great, thanks! I thought they switched the process for post 10' years, so I didn't even think to try your approach initially.

    XTOOL D7 Not Giving Option to "Add a Key" for 2012 Yukon XL

    Has anyone used the XTool D7 for key programming on Yukons? I have a 2012 Yukon XL Denali that I am trying trying to program a key for. This is one of the years after the switch to no longer be able to do it natively in the truck. I was able to program the remote (with buttons), but I cannot...

    Tapping into Fuse Box for Portable Head Unit/Dashcam Combo. Best Fuse to Use?

    Hello, I am trying to tap this portable head unit with integrated dash cam into my fuse box so as to not drain power from the battery when the truck is off. The issue is, when I hooked up the multimeter to the fuse box on the driver's side, I couldn't find a good fuse to tap into safely. I was...

    I appreciate any help

    I have always been curious about these small vxdiag type tools that connect to a laptop versus an xtool, autel, launch ~$500 tool. Have you compared it to any of those?

    Occasional No Crank When Turning Key? Ideas on Causes?

    Hey everyone, I went through and checked connections and did notice that the negative terminal cable was a little loose. Not extremely loose, but loose enough to justify tightening. After doing that, I haven't noticed the issue. I'll let you all know if anything changes. Thanks for all the help!

    Occasional No Crank When Turning Key? Ideas on Causes?

    Twice today I had the same issue where I try to start er up, only to be met with dead silence. No power. No lights. No cranking. After this happens, there are electrical popping noises happening throughout the cabin. The first time, I walked outside to check under the hood (didn't change...

    2012 Yukon XL Denali - Recommendations for (close to plug and play) aftermarket stereo head unit?

    I have heard a lot of good things about the maestro adapter, but as far as the other adapters, do you remember what all you needed? Do you remember which head unit you ended up getting?

    2012 Yukon XL Denali - Recommendations for (close to plug and play) aftermarket stereo head unit?

    I have been looking for a solid aftermarket car stereo that can give me Android auto and Apple carplay. I have looked into a couple of different options, but I cannot find a good one that can still use the factory cables that come with the stock Denali head unit. I tried one of these from...

    When using the infotainment screen for normal uses, such as radio, navigation, aux, etc it is a normal brightness that isn't an issue. However, when connecting a Chromecast/Google TV device (via HDMI to component adapter), the display becomes really dim when navigating the composite window in...

    How long to leave engine running safely without coolant on 2012 Yukon XL?

    There are a couple of unique aspects to this scenario that I think need to me mentioned: I recently purchased a 12' Yukon XL (with the 6.2L) with a known coolant leak. I am believing it to be the radiator, but could be the water pump. Since there have been delays in me diagnosing, the coolant...

    Rust on 2009 Yukon Denali XL

    Hello, I recently came across a pretty good price for a 2009 Yukon XL with 170k miles. What I have seen so far looks pretty good, except for the passenger side rockers and rear quarter panel. I am noticing a decent amount of rust, and wanted to get some feedback from you all on whether or not...
