    What models have AWD ? Tahoe / Yukon / Escalade

    Wow - thank you so much for the info ! I'll be keeping my eyes out. My wife, my 5 year old daughter, my 28 year old niece, and our dog was there when they were hit in the back. They are OK. My wife got a bruise on her arm and a little sore. Minivan came from behind fast and hard. :( Thanks...

    What models have AWD ? Tahoe / Yukon / Escalade

    So our '11 Denali is totaled. We gave it up today. Looking for another one for the family. One of the things I like for my wife is the All Wheel Drive. I am wondering what models and/or trim packages come with AWD - or does it depend on whether it was an option added. I will be looking for a new...

    Towing w/ Yukon Denali w/ air ride pump - how to not have the pump going on and off all the time

    OK thanks. I will check to see where it's leaking. If/when I find the leaks, where is the easiest place to get parts? rockauto? stealership? So if it is the bags on the shocks, I need whole new shocks? or can you get the bag part? Sorry, just not familiar. Thanks for help or links of where to...

    Towing w/ Yukon Denali w/ air ride pump - how to not have the pump going on and off all the time

    Hi there. 2011 yukon denali. Want to tow my 5500 lb camper. When I hook to it, the air ride pump turns on (of course) and then runs for a bit then shuts off. Then under a minute it starts up again. I am thinking it just keeps running on and off. Since I've already had to replace the pump twice...

    AFM delete / Tuner for 2011 Yukon Denali 6.2 Question

    I ended up getting a diablo i3 tuner. $350 off eBay. I just turned off the AFM and did a small increase in shift firmness for now. I didn't really look into it anymore yet. The change from V4 to V8 back and forth bugged me and I wanted that gone first - so very happy now! Now the only other...

    AFM delete / Tuner for 2011 Yukon Denali 6.2 Question

    The year in the title isn't sufficient? I have not had spark knock at all on my yukon, but I am running premium now, and do not see/feel much difference, but I am sure it helps. Thanks for the input 91RS, kbuskill, swath diver. I'll look again at diablo, hyper tech, and blackbear.

    AFM delete / Tuner for 2011 Yukon Denali 6.2 Question

    Posted in the wrong year forum. Reposting here..... Can someone point me in the right direction? I think I would be OK with just turning off the AFM, but if it's $200 for just that and for $265 I can get a tuner then I would prefer the tuner for the octane I run, tire monitor, performance...

    Service stabilitrak, traction control warning :(

    Update: I stopped at the gas station and filled up....noticed my brake lights were stuck on. Had the wifey hit the brakes once...they stayed on...hit it again, then they came off..... I'm hoping that this is because my brake switch is sticking or something. Anyone else have ideas? Thanks
