    20 Yukon Taillight 1 LED out

    FYI: I bought a used left tail light that was beat up (but working) to replace the non working light because I just didn't have $600 bucks to buy a new one. I got it in and installed and THEN I found the repair service! So I left the beat up light in temporarily while they repaired my good tail...

    20 Yukon Taillight 1 LED out

    Lot of guys on eBay that will fix your light for $50 bucks, I bought one for my wife's Yuke. Bought the truck from a dealer in another state and the left tail light was out, so they paid a dealer in my area to replace it. The GMC Dealer charged $1146.00 to replace it!!!!! Holy Shitbiscuits...

    8L90 Logic

    Do I still have to use a tuning software program to make those changes? HP Tuners or something similar? Chad

    8L90 Logic

    '17 GMC Yukon XL Denali 8L90 98K miles. I changed the fluid in the pan with the new Mobil 1 LV ATF HP recommended fluid, I did not drop the pan and change the filter, I changed only the quantity in the pan, about 7 qt's. The dealer did a Trans Service at 72k but they did not know what fluid was...

    285/40 vs. 285/45

    My Denali came with 285/45 22 if I change all four (4) tires to a 285/40 22 then I should NOT get the warning; "The overall diameter variance of the new tire is -1.12 inches, which is -3.44% different than the original. You should never go beyond 3% of the original tire, otherwise you run the...

    What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

    Changed the Trans Fluid and added the New Mobil 1 Synthetic LV ATF HP fluid along with the Superior Cooler Flow Bypass Kit. I didn't change the filter because the Audi dealer that we bought the Yuke from had did a Trans Flush & Filter 3 months before we bought it, but they didn't know what fluid...

    What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

    I've got an 'Addendum" from my Starter replacement last week! I think that's what its called, an addendum, that means I screwed something up and realized it and fixed it!! My Wife's Yuke wouldn't start so I swapped relays to make sure the relay was good and I looked at the fuses, all seemed to...

    2017 Tahoe - vibration / Buzzing sounds on acceleration

    Transmission Mount or U Joints come to mind. Take a floor jack and lift the transmission (with a 2x4 or 2x6 between the jack & tranny) and see if it lifts a little and exposes a busted mount. If so replace the mount. Grab the drive shaft and try and twist it or turn it or shake it, push it or...

    Magneride replacement struts - need input

    I posted this a little while back about the MagnaRides: SK-4261 has a 1" white spacer underneath the coil spring. That spacer lifted my '17 Yukon XL 2WD a Full 1" from it's original ride height. It was actually an 1 1/4" rise depending on how you looked at the tape measure. MR-3840 has a 3/32"...

    What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

    Replaced the Starter after it stranded my wife in the 7/11 parking lot. Easily swapped, took me 30 min maybe to R&R it. Chad

    Sounds Like Lifter Tick but Rockers All Moving

    Been wanting a reason to buy a good scanner, my Harbor Freight Code Reader does what it's supposed to but that ain't much! But I would rather spend that cash on a wheels, tires, exhaust, golf clubs, a shed in the backyard or a new Lazy Boy recliner! Can I get an Amen! Chad

    Sounds Like Lifter Tick but Rockers All Moving

    Doubeleive, I thought about a compression check but I don't think this would yield any results from the problem that nickbeckss mentioned. I ticking sound (in my opinion) is something light like a lifter or an exhaust leak or an injector. A Compression check leads me to think about a Rod knock...

    Sounds Like Lifter Tick but Rockers All Moving

    Hey dude, I'm sure you've read in this forum about the DOD Failures, seems like a good idea from GM but they didn't quite get it right. I'm not there to here the tick but if it's determined that one of your lifters have stuck then this SDPC solution might be a good idea for your application. It...

    17 Tahoe makes squeaky suspension noises

    The Jounce Bumpers are used so you don't get metal to metal contact from either the Rear Axle or front control arm to the frame. I might be wrong here but, these really shouldn't come into play unless the truck is loaded down with cargo or a trailer. Squeaking from the truck usually means a...

    Sounds Like Lifter Tick but Rockers All Moving

    Hate to see ya on this forum with no responses so I thought I would chime in. I'm assuming you looked over the rest of the motor for harness damage so lets assume that problem(s) is fixed. Does your 5.3 have the DOD? I learned a little bit of knowledge watching this and you know what they...

    2015 GMC Yukon XL SLT Apple Carplay

    My '17 Denali has the Apple Car Play and to be honest, I don't think its worth it. Other than the "Neat" factor of having emails or text messages spoken to you via the sound system in the truck, there's not much else to it. I would say that about 75% of the features available can only be...

    What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

    Wires, plugs and replaced one coil yesterday. Still have #8 plug/wire to R&R but I have to remove the rear heater core coolant lines to get to the plug. Shame on GM for routing those coolant line dead ass on top of that plug!! Gonna change rear-end fluid today, change trans fluid tomorrow while...
