    L87 Glitter party after oil change

    So the selling dealer did the Pico test (vehicle passed) to my new-to-me 2023 Yukon on 1/27/2026 at 48,967mi and updated oil to the 0W-40 viscosity. I did an oil change this week at 50k miles to get on even 5k intervals. Also added a catch can and Range DFM disabler. Concerned to see this…...

    Dipstick tube size for oil analysis sample

    For those of you that have pulled an engine oil sample through the dipstick, what size of tubing did you use? I've tried a 1/4" OD hose with no luck. It seems to hit a hard stop before entering the pan. An image of the dipstick appears to show that it necks down at the bottom. I've got some...

    Anybody looked at trying to add the GM "underbody skid shield package" on their 2021+ suv from the accessories website?

    Part No.: 84962765. Searching that part number appears to indicate it's for the ZR2 trim pickups https://www.gmperformancemotor.com/parts/84962765.html?srsltid=AfmBOorTFqAfvzUyAbqN6IpI85RU8VHbmLU_4Cbe63wUYu_phPdOrGWl.

    2025 AT4 vs AT4 Ultimate wheels on a 2023 Denali Ultimate?

    Need some opinions. I've purchased a 2023 Yukon Denali Ultimate in Onyx Black with 22" wheels (in transport so no pics yet). I'd prefer a 20" wheel and like the look of the 2025 AT4 versions. Problem is I can't decide if the Carbon Flash Metallic wheel that comes on the AT4 or the Talos...

    Never seen this before - Parking Brake Shoe Replacement Help

    176k miles, vehicle specs in sig. @swathdiver @Doubeleive @petethepug and anyone else. A couple weeks ago, I replaced my rear pads and rotors. I noticed the RR parking brake shoe did not have any pad material left on the metal ring. There were no pad material chunks or excessive brake dust...

    CV Axle Noise During Low Speed Maneuvers?

    Searched and didn't see anything that addressed what I believe is my issue. Is it possible for the CV axle(s) to make a "whirring" sound? Is that an indication of anything going bad? It's primarily noticeable at low speeds (<5 mph) when turning (2wd is selected on the dial). Especially when...

    Rear Leveling & Z55 Suspension

    Has anyone successfully raised the rear ride height (1-2”) on a vehicle with the Z55 air leveling shocks? I have a 2012 Suburban LTZ and have installed the Suspension Maxx leveling kit in the front (1.5”). There’s a small amount of rake towards the rear. I’d like to raise it about an inch...

    Front & Rear Heater Core Flush

    I’m changing fluids in my new to me 135k mile 2012 Suburban and the coolant is next. While doing so, I thought it might make sense to flush both heater cores. I haven’t seen much info on flushing the rear one. Is there anything I need to be mindful of? Sent from my iPhone using Tapatalk

    Center Console Compartment Light?

    Do the GMT900 consoles have a compartment light? It looks like there’s a spot for one, it’s difficult to see based on location. Sent from my iPhone using Tapatalk

    Sensor PM

    I have a problem. I like to find reasons to do preventative maintenance on my vehicle. This causes side effects of a lighter wallet and time spent. That said, at 8 yrs old and 135k miles, is it prudent to replace any sensors? Some examples would be MAF, MAP, O2, vapor canister purge valve...

    Floor Liners and Mats

    What’s the consensus here on a floor liner and/or mat brand & type to use with the GMT900s? Saw the Husky X-Act Contour and Weatherbeater. Not too clear on the difference. I need to get something for the Suburban. I’m thinking liners up front for sure. Haven’t decided whether to do carpeted...

    2012 Suburban LTZ 4wd Inspection - Have questions

    So I brought this vehicle home last week and I’m looking things over throughout. I wanted to get some input on a few things I found. First, a little history. It’s a 3/3012 build and spent the first 8 months of its life as a GM corp vehicle in Michigan. Then the rest was spent in Texas in the...

    Swapping intake manifold & throttle body on a 5.3

    With an otherwise stock motor, is there any benefit to swapping a truck 6.2L intake and a Corvette/Camaro (I believe) throttle body onto a 5.3L? I searched and didn't see any info on it. Of course, that could be operator error.

    2007 - 2014 GMT900 SUV Model Updates

    I'm getting ready to pull the trigger on a 2012 Suburban LTZ 4wd. I'm not too familiar with these models as I am the K2XX and GMT800s. I'd love to know what updates GM did to this platform over the model years (electrical, mechanical, cosmetic, etc). I did some searching, but didn't find a...

    Looking for 2012 - 2014 Tahoe LTZ - Opinions Needed

    I'm looking for a Tahoe LTZ 4WD and wanted some opinions about factory options. Specifically, HD trailering, 2nd row captains chairs and sunroof. Finding one with all those would be ideal, but seems to be a unicorn. I've found some with the HD trailering (additional fluid coolers, 3.42 gears...

    Circuit 6844 - Need Help

    Hoping any of you with the factory power assist steps (RPO BRS) can help me trace a wire circuit. Specifically, I’m looking to see if GM put 2 blue/yellow striped wires in position 42 on the body side of the X225 body harness to instrument panel harness connector. It’s gray in color and...

    Yukon Headlight Alignment?

    Anyone know how to align the headlight housings for a 2015 Yukon? I swapped in OE HID housings and need to align them. I see what looks like one alignment screw, but I'm hoping someone here has experience doing it. Sent from my iPad using Tapatalk

    Denali Cluster with Heads Up Display

    Installed a Yukon Denali cluster and HUD unit in my 2015.5 Yukon SLT this weekend. The cluster had to be programmed to my vehicle and to enable HUD functionality. I created a custom wiring harness as the only way to add those connections is through swapping the I/P harness. The rest was just...
