Hi all, from Spartanburg, SC: I just bought a 2012 Yukon Denali AWD (with 98k miles) as a replacement for my old 2002 Ford Expedition. My only other experience with a GM truck was a 1996 S-10 I owned years ago. It was a piece of junk. But that's another story for another forum. I've heard lots of good things about the third-gen Tahoe/Yukon/Escalade, and hope to enjoy it as a frequent road trip and tow vehicle. I specifically wanted the 6.2L engine, which I really love. I can't believe how quick this thing is! As a byproduct of my choice, I got a fully-loaded SUV with a decent ride, great acceleration and better handling than the Ex. It took me a while to find it, as I wanted black with the towing package and a bench 2nd row seat. That seems to be a rare combination. I like to customize my cars. My Expedition is lowered with lots of parts from Lightning and Harley trucks swapped over, billet grille, etc. I've been thinking about what I'd do to the Yukon, and honestly I'm struggling to come up with much. I'd like to lower it 2-3 inches. And I'm not a fan of the wood trim pieces inside. I'll swap to better looking wheels at some point. But that's really it, I think. It came with tinted windows (done by PO) and every option under the sun. I'm even happy with the sound of the stock exhaust. Right now, I'm touching up a few little paint chips, ordering a set of owner's manuals (why do people sell these out of their cars?!?), a Haynes repair manual, rubber floor mat for the rear (I removed the 3rd row seats), and learning what the many buttons do. I still haven't figured out where the Bluetooth is, lol. I have a few newbie questions: What's the conventional wisdom on Dex-Cool antifreeze? I've heard it has corrosion issues. The dealer showed me their service records for the car, which included a radiator replacement. It's been refilled with fresh Dex-cool. Should I switch to something else? Is it possible to lower this by a couple of inches without too much loss of ride quality? I was able to use drop spindles and air-ride adjustment on the Ex to drop it that much. All I really had to do was swap to shorter bump-stops on the rear. And it rides about the same. The one video I've seen of a lowered Tahoe looked straightforward. But ride quality wasn't really discussed. Also on the lowered Tahoe video, for some reason they had to move the rear anti-sway bar to one side by an inch. Why would that be necessary? My Yukon was originally sold and driven in Oregon for four years. So I'm going to do a more thorough inspection for rust. What are common areas to look out for? All I've seen so far is light surface rust on the exhaust and drive shafts. So that's it for now. Looking forward to many miles of fun and utility with the Yukon. Thanks in advance for any helpful advice.
