    Tailgate / Liftgate compatibility

    I messed up big time yesterday and backed into my garage wall with my truck. I dented the tailgate up badly. I am looking for a replacement and finding a lot of "power liftgate" ones. My truck came with a manual liftgate. Will a power liftgate bolt in assuming I retain my manual lift struts or...

    [FOUND] Wanted: PPV steelies with caps

    I think I want to ditch my 20's and go with PPV/SSV black steelies and center caps. I'm located in NY state but I will pay shipping costs if necessary. I'll consider just the wheels or wheel/tires together. Also would be willing to trade my 20's with excellent Michelins on them for a set of...

    Second row bench to captain's chairs swap

    Guys I KNOW this has been discussed at length here before, in fact I vaguely remember seeing someone post a lengthy "how to" on the subject, but I just cannot find it now for the life of me. I am looking to swap the 2nd row bench to captain's chairs in my 2012 Tahoe with black leather interior...

    Homelink roof console plug & play?

    Guys my 2012 Tahoe came with a non-homelink roof console. Ones with the Homelink module/buttons are pretty cheap on eBay, does anyone know if the wiring plug would be there in my truck and if I can just grab a homelink unit and put it in place of the one I have?

    Upgrade to Nav unit 2012 Tahoe

    Can I swap this OEM stereo out for one of the ones with the screen display? How much of a pain is that while retaining SiriusXM, etc.

    2009-2014 6L80 better than 2015+?

    The transmission in my 2016 Suburban made it to around 100,000 miles before it gave up and cost me $5000. I'm looking at a 2012 Tahoe and was wondering if the older 6L80's were free of this horrible torque converter and high temperature issues that the K2 trucks have? I don't know much about...

    Rattle under dashboard!

    My truck has developed a serious rattle under the dashboard. It's coming from the dead center of the dash up by the windshield right where the "security" light is (that little red flashing LED). Anybody have any idea what could be under there rattling and can anyone point me to a "how-to" on...

    Help me choose a cat-back!

    Well, after cutting and splicing on my factory exhaust way too much, it's finally starting to give up. Since I bought the truck in January 2020, I've fiddled with the OEM "norma" clamp and never gotten it to seal right, I've had aftermarket mufflers welded in and cut back out, I've had my...

    The transmission monster finally got me?

    I'm at around 94,000 miles on my 6L80E. Shifting fine, no issues up to a couple weeks ago. After my wife took it on a long road trip, the next day I started to notice a high-pitched mechanical "whine" that would come in just prior to upshifts at higher RPM. Shifts were noticeably jerkier and...

    Calling all GMT400 Z56/PPV experts...

    I'm looking at buying a 99 Tahoe PPV/Z56 police package. I wasn't on the hunt for one but one came up and damn, you just don't see these anymore. Question is, what was the original tire and wheel size for these trucks? The owner of the truck has some ridiculous aftermarket wheels on it and I...

    Ground issue?

    I'm not sure if this has been discussed here much but I'm curious how common this issue is on the K2 Tahoe/Yukon/Suburban trucks (seen a lot of Silverados with the issue on YouTube). I recently had been experiencing slower "ruhr-ruhr-ruhr" type start-ups, then some days my radio would randomly...

    Help me transform my Suburban into a PPV look-alike

    My 2016 Suburban LT has been through a couple versions. First was as delivered LT with 20" wheels. I then added a slight leveling kit front and rear and Z71-spec wheels and running boards with upsized tires. I'd like to take the leveling kit out and run some PPV steelies on 265/60/17 Goodyear...

    P0442

    I know...I hate to post a question about an EVAP code but I have to ask. I did search but didn't find much. My 2016 Suburban tripped a P0442 the other day. I know fuel caps are usually the culprit for the P0442 but this is a capless system. Does anyone have any other suggestions that may be a...

    STP "direct injection" system cleaner

    Has anyone tried this stuff? Direct Injection Fuel Injector Cleaner | STP.com First time I've seen a product like this aimed directly at us GDI owners. I'm kind of curious how it works without being aspirated into the intake somehow. If you just put it in the tank how the hell does it reach...

    16 Suburban wind noise 60+ mph

    Has anyone experienced and/or identified the source of a pretty significant wind noise at 60+ MPH? It's coming from my driver's door somewhere, it sounds like it's right in my left ear while I'm driving. The truck didn't do this when I first bought it, I'm wondering what could have changed or...

    Need help from a 2017-2020 Suburban Z71 owner

    Does anyone here have a 2017-2020 Suburban Z71 that would be willing to crawl under their truck and get me the part numbers for the OEM tubular side steps? I cannot find them listed online ANYWHERE. I founds two sets at wrecking yards but they want gobs of money for shipping. Anyway if I could...

    G80?

    My RPO list says I have a G80. When I had the truck up in the air the other day, I spun the rear wheels and when one went forward, the other went backward. Any shadetree mechanic worth his salt will tell you that this would tend to indicate an open differential. If I truly had the limited...

    TPMS - do I need the dealer to save me?

    Guys, I recently (last week) had some new tires put on. For the last week, the TPMS sensors have been working fine, all reporting pressures. I know that I had to re-learn them because the wheels were put back on in different places, so my pressures weren't showing for the right wheel. I have...

    Help with squeak after level

    Guys, I just installed Suspension Maxx 1.5" front and 1" rear level. Here's how I did it: Front: Raised, supported truck. Let front end droop as low as it would go. Removed lower strut bolts, dropped A-arms down and was able to slip the lift block in without removing anything else (took some...

    Norma clamp!

    Guys I can't get this damn thing to stop leaking. It started with a light "tick tick tick" on cold start that I traced to this clamp/coupler. I ordered a replacement in accordance with the directions in this bulletin: https://gm-techlink.com/?p=7001 I broke the bolt of the first GM replacement...

    1" front, 1" rear lift - what tire size?

    Guys I'm adding an inch in the front, and an inch in the rear (because I want a bit more clearance in the front but I like the raked look). What would be a good size tire to go along with this? Has anyone done a 1" and 1" on their K2? I'm thinking one size up from stock with 275/60/20's. Think...

    Exhaust leak sound 2016 Suburban

    Hey guys, I've noticed that my truck has developed kind of an exhaust leak "ffft ffft ffft ffft ffft" sound on cold startup. It disappears within about a minute of warmup. It's coming from the driver's side undercarriage. I haven't gotten under the truck to look around yet. I say "developed"...

    Performance muffler welded in place of OEM

    Guys, I'm looking to purchase an aftermarket muffler. I am going to cut out the OEM muffler and flapper and weld in a replacement muffler. I have heard that the OEM pipe diameter at that point in the exhaust system is 2.75" which is weird. Can anyone confirm what size the pipe is on my 2016...

    Daytime running lights

    Can anyone tell me why, on my 2016 Suburban LT, the daytime running lights are the headlights and not the white LED strip? Pretty much every other K2 Suburban or Tahoe I see, the DRL's are the white LED strip but on mine, they come on as the headlights. And yes, I do have the LED strip - it...
