have an '04 burban 4wd .. same noise after initial startup .. pull away and 5-10 seconds there it is... I believe that noise is the Stabilitrak system kicking on.. our older '01 burbans.. both mine and my wife's without Stabilitrak didn't do that...

New XL Denali Owner - Q about break-in & towing by mikesocal
Dec 30, 2005 (10:54 am)

Well, I took the leap and purchased an 06 YXL Denali with all the options (NAV, RES, Sunroof, buckets). Very excited!
 
Regarding break in of the vehicle. Just how important is it to not go over 55 mph, and to not shift down, during the first 500 miles? I'm fairly certain that both of those things have already happened just in the course of the dealer transferring the vehicle from another dealer. The freeways here in Southern California have everyone driving at high speeds (70+), and I'm willing to bet that whoever drove it down could have easily used engine braking at some point. The vehicle had about 100 miles on it when I took delivery.
 
Regarding the topic of being towed. The manual clearly states that the vehicle cannot be towed, otherwise the drive train will be damaged! Now, given that every vehicle I've ever owned has been towed at one time or another, I just want to make sure I understand what they mean by towing. The manual talks about the fact that the wheels cannot touch the ground while being towed. So, that means towing the vehicle should always be done via a flat bed truck. I'm ok with that.
 
However, what about just moving the vehicle at slow speeds, such as when getting it up on the flat bed?
 
Or what about pushing it out of my driveway to jump start it?
 
What about getting pulled out of the snow or mud via the recovery hooks?
 
I guess I need to make absolutely sure that the vehicle never "coasts" in neutral at more than a walking pace.
 
Sorry if the questions seem silly. I've never owned an AWD (or even a 4WD), and I'm excited about using it for family treks to mountains, snow, trails, and good old road trips. I want to make sure I make the thing last and keep it working well.
 
Anyway...any info you have is appreciated. I'm also going to call the dealer and see what the service guys have to say.
 
Thanks.
 
Mike

Yes, my car does have stabilitrak and your explannation sounds reasonable. Will other Yukon XL owner share your ideals?

Ideas for increasing height a few inches? by mikesocal
Dec 31, 2005 (9:08 am)

I'm interested in bumping up the height of my new DXL a few inches, just so that I can get some better ground clearance for the occasional trails that have some deep dips, as we make our way with the bike rack (with 4 bikes) on the back.
 
Has anyone here done anything like that? I've done a little research on it, and it appears that full blown suspension lift kits aren't available due to the autoride (nor would I necessarily want such a major modification). I've heard of something called a "body lift", not sure about the difference.
 
Any insight is appreciated.
 
Thanks.

I think the nav disc version is currently (last time I checked) at 4.1; where one can be purchased depends on how much you're willing to pay for it. Unless you have a nice business relationship with the parts and/or sales manager at your favorite GMC dealership, you will need to shell out quite a few bills for the disc if bought at a dealership. Ebay is probably your best bet if price is an issue...

Re: Are 18" custom wheels/tires a good compromise? [mikesocal] by tdoh

I can't offer an opinion as to how good a compromise 18" wheels/tires will be for off-roading/snow/etc. since I've never tried them out; I guess it would sorta depend on how aggressive you'll drive your vehicle under those types of road conditions--e.g., really rocky roads, deep snow drifts, etc.
 
FWIW--I'm running 22" wheels/tires on my DXL and for the most part, try to avoid road conditions that are really adverse for those sized shoes. However--I have driven on snow-covered roads (2-3 inches deep) and on fairly-rugged (i.e., no large rocks to drive over) dirt roads on my 22's w/o any problems...of course, I do drive a bit more conservatively than I probably would if I were running on the stockers. Potholes--well, I know I'm taking my chances in that regard--but as with any kind of choice, there will always be compromises.
 
Just my opinion, but 18" is not much of a compromise if "big-wheel" look is part of the equation since there isn't much of a perceptible difference from going up only 1" in size. I think that as long as you drive a bit more conservatively under such road conditions, 20" is a much better compromise in both looks (size-wise) and performance. OTOH--since you mentioned about the possible need for using snow cables...I guess it would be a bit difficult to find cables for 20" tires although I would imagine that it might only be a matter of time before some manufacturer starts offering them, what with the increased proliferation of big wheels/tires being offered these days.

Congrats from one DXL owner to another on your purchase--I'm sure you'll enjoy driving it! If you're one of those types who are open to trying to get more power out of your DXL, you might want to consider a custom PCM tune...I did and it's the best bang-for-the-buck aftermarket performance add-on I've ever purchased for my truck.
 
About the vehicle towing issue--the AWD system on the Denali cannot be put in neutral (I'm not talking about putting the tranny in neutral--that's a different thing altogether) unlike that of most 4WD vehicles. The technical explanation that describes why this is so eludes me at the moment (someone please help me out) but suffice it to say, it is because of this issue that the Denali cannot be towed at speed w/ all four wheels touching the ground. You can however tow/move it at very-slow speed (e.g., pushing it) for very short distances such as during those situations you mentioned w/o risk of damage to the transfer case.
