    Hey all installing a kenwood with maestro rr. Any tips on how to route the chime speaker? Not sure if there’s an easy access panel anywhere to get it from behind the head unit to somewhere in the dash area or below the steering wheel somewhere

    Carplay on front screen, different media on LCD screens?

    Hey all, I am going to pull the trigger on this unit and eliminate my DVD player. I am a noob with this stuff, I'll do engine stuff all day but I don't have experience with all of this. It seems like a lot of moving parts. Anyway, it's this unit...

    P0335 (crank pos sensor) issue

    Hey all, I have been having issues with my 2012 6.2 swapped Yukon since I got it back together after a head gasket repair. It was fine for a hundred miles or so, but I got on it hard the other day and it's been having this issue ever since. It is sporadically throwing a p0335 code which leads...

    Backfire and sputter

    Getting an intermittent backfire and sputter in my truck lately and it won’t be able to accelerate for about 10 seconds then it clears up and everything is fine. Happens about once a week or so. It threw a code once and I believe it said something like fuel pump low voltage or something of...

    Any aluminum radiators that don't crack annually?

    Hello, I have a mishimoto aluminum radiator. The first one cracked within a couple of months. The second one lasted about a year and a half. I am tired of spending money on the shipping for the warranty and the extra money each time I have to change the coolant. I read reviews of cold case...

    Welp broke something serious

    Ha it never ends lately. Fixed the motor problem... Now I got a driveline problem. Engine is feeling incredible since I fixed the tune, so I've been having some fun with it last couple days. On a 1-2 shift, I broke something. Something is seizing up intermittently, most notable around...

    Lifters, piston slap, or normal?

    Since my 6.2 swap, my cold starts just sound terrible. I had many cammed vehicles and never heard them be this loud on cold start. They are Johnson 2110 lifters, which I heard can be noisy cold. They are quiet when fully warmed. If it was piston slap I'd just live with it, but the sound...

    Front diff or transfer case?

    Hey guys, having a front diff issue I think. When I am in Auto, I can hear a whine under light acceleration. Definitely sounds exactly like differential whine. I am not sure how Auto mode works, so I wasn't sure if it was for sure the front diff or possibly the transfer case. Is Auto mode...

    high RPM vibration when A/C is on only

    Hey all, have a vibration going on. Feels like when you drive over rumble strips on the road. I thought something in my driveline was fucked, so I started poking around at the u-joints, the flywheel, and the TC. Everything looked good. I went to test today and miraculously it was not doing...

    Successful sound deadening for headers?

    Hey all, I am enjoying my 6.2 swap very much. One thing that is really starting to get on my nerves is the header "tinny/airflow" sound you hear constantly in the cabin. It wasn't as bad on my 5.3 because of the lower lift cam and smaller engine. But on the 6.2 it is starting to irk me...

    Tow hitch cover?

    Hey all, my 2012 yukon SLT was in an accident so it's at the body shop for rear bumper repairs. While it was there, I asked the owner if he could add the tow hitch cover. He mentioned only the Denali had this cover? Is there an aftermarket cover that will fit the standard bumper? I'd like to...

    Oil pressure sanity check

    Hey all, figured I'd make a thread since my hot oil pressure is bothering me. I pulled my 5.3 out for a junkyard 6.2 with about 50k on it. I replaced all the gaskets, put in a melling 10355 oil pump with standard spring, new VVT cam and Johnson 2110 lifters. I stupidly didn't plug the oil pan...

    Making Yukon look a little more modern?

    The Tahoe's from this generation are timeless in how they look, but IMO, the Yukon with it's front nose styling is looking very dated. I have an SLT XL 4x4 that is being upgraded to a 6.2, so I plan on driving it for a while. I have already removed the side trim which cleaned it up a lot, but...

    2015+ Side Trim on GMT900?

    Wondering if the factory denali chrome side trim will fit properly on GMT900 Yukon XL? I am just unsure if the doors have the same curvature, or if that even matters. Something like this. https://www.shopsar.com/gmc-yukon-chrome-body-moldings-p/cbm-300-gmcyukon.htm

    Corsa Touring 14915 - 2009+ Suburban/Yukon Xl/Avalance

    Selling my 3" Corsa Touring with inline Vibrant Ultra Quiet resonator. This is a great exhaust if you have headers and are looking for some more sound over the stock mufflers. It is quiet at part throttle but will scream at wide open throttle. I added the resonator which completely cleaned up...

    What is this connector/wire?

    Going over my 6.2 junkyard motor and found this. Appears to be spliced into a 3 prong power connector? Doesn't look factory and from what I can see on my existing 2012 5.3, this isn't on the block.

    Exploding driveshafts?

    Do us SUVs with 4x4 have the same exploding driveshaft issue over 100 mph? I am modding my engine to about 420 rwhp and this concerns me to say the least.

    TVS or Whipple on 5.3?

    Anyone have any experience with the 1900 TVS or 2300 whipple on a 5.3? Curious about part throttle drivability. I wouldn't want it to be like a light switch going off. Don't see much info here regarding superchargers.

    Corsa Touring connected to catted Kooks

    Just put these on. Sound is awesome. Idle is slightly louder than stock, but much much deeper. Light throttle is about the same. Wide open sounds like open exhaust lol. Just not sure they're a good match for a mid 15 second truck lol. Might take em off and put em back on when I do the...

    Rear wiper clunk

    My rear wiper clunks real hard when it disengages and goes back into the the little plastic holder. It looks like it's the bottom tab on the wiper hitting the housing. It only started doing this after I had my hatch repainted and I guess the body shop had to remove and put the wiper back on...

    Does 2015+ catback fit this generation?

    Stock catback looks pretty rough at 145k, I'd like to swap it out for the magnaflow. I noticed the 07-13 does not have a resonator but the 15+ does. I really want a built in resonator at the tailpipe because I have headers. For GMT900...
