    Towing Heavy

    True, I'll try to adjust load to the front. The axle ratio is 3.08 I'm in Houston, but I had a trailer tire blowout near Hillsboro TX, and then a second blowout 30 minutes later, and limped at 5 mph on the shoulder to the Bucc-ee's there, and spent the night in the parking lot. I bought new...

    Towing Heavy

    I have factory air shocks and spring helper bags as well. Do you think I need to adjust the WDH? It was set by Holiday World before I put the spring helper bags in.

    Towing Heavy

    Hey everyone — wanted to share a detailed breakdown of my towing setup. My combination is a 2016 Yukon XL and Keystone Bullet 2730BH (6550 lbs loaded). I am 220 lbs under the Yukon GVWR, and ~20 lbs under the rear axle rating by relocating the spare tire to the trailer and only carrying kids...

    See I requested an "intake service"at my shop. I've attached the invoice from that work, does this look right to you?

    Proactive maintenance - New to me 2023 Yukon SLT 5.3 60k miles

    Thanks for this. By wires do you mean replace the engine wiring harness? And by intake service do you mean engine air filter only? (I guess I'm handy, but not a mechanic).

    2018 GMC yukon xl SLT Grille guard

    Following. I have a 2016 and had a deer strike a few months ago, now I'm on this same quest. From what I have read thus far, you will need parking proximity extensions for the two center sensors, and you will need to trim square holes in the front fascia trim to attach the brush guard to the...

    Proactive maintenance - New to me 2023 Yukon SLT 5.3 60k miles

    I've purchased a used rental 2023 Yukon SLT with 60k miles. I'm looking through the threads on the 5.3 L84 and the 10L80. I'm trying to learn about this coming from my 2016 Yukon 5.3 6l80 world (which I still own). Below is what I'm gleaning from searching the forums. Can you gents offer some...

    Bought a “30k mile” 2016 LTZ… turned out to be ~200k miles (odometer rollback) – warning to others

    Autonation. I honestly think they had no idea and got scammed too. They said they will take a loss since they bought it back for what I paid. They said the car will go to wholesale and the odometer discrepancy will be disclosed and follow the VIN going forward.

    Bought a “30k mile” 2016 LTZ… turned out to be ~200k miles (odometer rollback) – warning to others

    It was Autonation. They bought it back. I lost Taxes paid. The alternative was arbitration. I don't know anything about that, so I took the buyback offer.

    Bought a “30k mile” 2016 LTZ… turned out to be ~200k miles (odometer rollback) – warning to others

    I'll go to the service department and get this printout for my records, in case I need more "evidence". Definitely will do this for the next one before purchase.

    Bought a “30k mile” 2016 LTZ… turned out to be ~200k miles (odometer rollback) – warning to others

    Hey everyone, I'm now a victim of odometer rollback fraud. I want to share what happened to me so others don’t get burned the same way. I recently bought a 2016 Tahoe LTZ from a national dealership chain. Super clean truck, great interior, and it even had a recently installed Jasper reman...

    2023 GMC Yukon AT4 6.2L dead at 10K miles

    MPG cutting is a problem too. Lifters fail, torque converter shreds its aluminum cover, to meet govt mpg requirements, all at the expense of the end customer. Saves you some gas, but you end up paying GM for parts/repair instead, so they come out ahead.

    2016 Yukon/L680 Transmission upgrades for HD TOW 2016 Yukon XL

    Our requirements are 6 seats and can pull the 31' 6k lb trailer in the attached pic. We may either upgrade the Yuke to a sierra 2500/f-250 with front center jump seat, or trade in the trailer and get a class C. The wife and kids are excited about being able to mess around inside a class C while...
