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.

How ironic!! I recently bought an 06 Yukon XL in October. Recently I noticed a grinding noise and they told me the same thing. I took it to a brake shop to get a second opinion and they said it is a suspension problem. In the process of checking on this lead..

thanks for all the info . . . mine is an '01 Yukon XL, but I'm having what may be a similar problem - speaker static. The static comes over the speaker, right when the vehicle is started and slowly (5-10 miles later) dissipates. It happens whether the radio is powered on or off. I recently took the vehicle in for a recall, some kind of fuel circuit assembly thing (I can't recall), but I do remember something in the recall information about a ground wire. I'm thinking when the dealer performed the recall, they didn't do the ground 'right', and in the few weeks after, it's worked loose, and that's what's leading to the static. The dealer told me it could be a blown speaker . . . but with static coming over it whether it's on or off . . . ? That doesn't sound right to me. Any advice on where I start looking for that loose ground . . . ? Thank you very much.

my '01 XL is coming up on 80K miles, and I haven't had any tranny service / work done. I need to check out the OM about when this should be done, but I'm thinking you did the 'right' thing and it failed anyway . . . yes?
By the way, the guy at the Express Lube says they offer two types of tranny service, one drains and the other, they put some kind of vacuum on it to really 'drain it right', or something like that . . . doesn't sound right to me, does it . . . ?

thanks to all who have posted on this problem (headliner / speaker(?) static / buzzing), and for directing me to the Tahoe board, where I found a similar problem . . . if this is in fact not speaker / radio / ground related, but rather an aspirator and / or fan related to the ACC, do I just pop off that little speaker-looking 'thing', and replace whatever's underneath, or . . . ? I've seen some mention of doing what may need doing by first removing the headliner, but that seems like more than I want to get in to . . . any advice is greatly appreciated, thank you.

Re: Ideas for increasing height a few inches? [mikesocal] by tireguy

You can squeeze an inch out just by adjusting the torsion bars which suspend your front end. You probably have enough slack to raise it a half inch or so in the adjustment bolts (support the front end with jackstands then tighten the bolts). Otherwise you need to remove the bars and rotate them to the next position, then retighten the adjustment bolts. Of course the more you raise them the more you will affect your handling. It's built in for fine adjustments, mainly leveling side-to-side, but it works for this too. You can then adjust your autoride height sensor to level the vehicle in the rear. Of course it's nothing like installing a 4-6" Fabtech system, but this is one of the few vehicles which can be lifted slightly without purchasing any new parts. You'll want to get a front-end alignment after messing with the suspension.

Thanks Chris. I'll hold off for now, however, if I do lift it, I'll probably want to go with 3 or 4 inches. I don't think one inch would be worth it. I get the impression that installing a lift kit on the Deanli isn't very popular, due to the complexities involved with the AutoRide suspension.

Yukon XL Spare Tire, Custom Rig, etc. by mikesocal
Jan 25, 2006 (6:14 pm)

I spent some time today getting to know my new XL Denali, specifically taking out the jack equipment, lowering the spare, making sure I could get it all the way out, finding the locations for jacking up the front and back, etc. It certainly isn't easy or clean work, but not terribly difficult either (although I didn't actually remove a wheel and replace it with the spare).
 
One thing I noticed is that the crank bar assembly used to lower the spare tire doesn't quite clear the bumper while making the revolutions. If you're real careful, you can tug on it just as it's coming around to the bumper for each crank, however, it's best to use a towel or something soft on the end of the iron, so it won't damage the paint on the bumper. If they had just extended the length another inch, that would have taken care of the issue.
 
I'm wondering if anyone has put together a custom spare rig that would allow a true full size (i.e. 17" or 20" setup) to be stored underneath the vehicle. I asked my dealer service advisor once, and he asked a tech, who said they had done it before. But now that I've spent some time underneath, I don't see how they could, unless they removed the spare winch and did some kind of welding of another cross-bar in order to properly center the location for the larger spare.
 
Has anyone heard of anything like that?
 
I ask because I've had true full size spares in the past, and they come in real handly. They can make a real difference, especially if you get a flat while on vacation, and you're in an area where there isn't an abundance of locations to get the tire repaired (e.g. up in the mountains enjoying the snow). It can really rob an entire day sometimes, and it's not good to drive on a wheel/tire that's a different size like that, particularly in winter weather conditions.
 
Please let me know if any of you have heard of a way of mounting a true full size spare (in my case, 17").
 
Thanks.
 
Mike
