    tire pressures? Shocks?

    -mike
  • Has anyone else experienced a horribly rough ride in the 04 DXL? The autoride system on my dxl seems to be set incorrectly as I feel every single bump in the road as if they were potholes. It feels almost as if there are no shocks or that the air shocks are fully inflated with no room to give.

    I've taken it to the dealer, they acted like I was crazy and let some air out of my tires which didn't help. At this point I'm preparing to trade in the dxl for something with a smoother ride if this is as good as it gets.

    I previously owned an 01 Suburban which rode like a dream compared to this. Any insight will be very appreciated.

  • Anyone have information on the incentives after the current offers expire on 9/30?

    My wife and I are looking at YXLs and DXLs.

    The incentives are great on the '04s right now, but most dealers only have black or white DXLs(the only colors we DON'T want) and most of the YXLs are SLT 1SCs or SLEs. I wonder if we wouldn't be better waiting till Oct 1st and working a deal on an '05.

    One of the reasons I'm leaning towards the DXL is autoride. We plan to tow with the truck...is it worth the extra $ to step up to the DXL, or do I save the cash and get the standard XL?
  • paisanpaisan Posts: 21,181
    Biggest thing I like about the DXL over YXL is the AWD system, it's way way better than the auto-4wd system on the YXL.

    Are you referring to the Autotrac 4WD setup on the YXL or the full-time 4WD one? If the latter, than are you qualifying your comment based on personal experience--i.e., have you owned/extensively driven both? I've own(ed) and driven both a full-time YXL and an AWD DXL, and in normal day-to-day dry and wet-weather conditions I could not discern a noticeable difference between the performance of the full-time 4WD and the AWD. Now I'm not saying that AWD isn't preferable to full-time 4WD, but to say that it's "way way better"? I dunno about that...
  • paisanpaisan Posts: 21,181
    I have extensive experience with AWD systems and ANY system that puts some power to both axles will help you better pro-actively than a system that is purely reactionary like the auto-4wd found in the Yukon v. the full-time one in the Denali where there is power to both axles at all times. Check my profile, I know AWD pretty good :)

    -mike
  • What is the split range of the AWD in the Denail between front and rear?

    That is how large/small of a percentage can be sent to either axle?

    Is the power/torque always split 50/50 left to right, or does that vary too?
  • paisanpaisan Posts: 21,181
    I'm not positive on the torque split on the Denali but if my research serves right it's 50/50 and can probably vary up to 80/20 and 20/80.

    Left and right is deteremined by the front or rear diffy, IIRC the Denali has an LSD in the rear which would mean that it could do 100/0 up to 0/100 split between the 2 rear tires.

    -mike
  • Mine is a 2002. According to the 2002 GM Service Manual, the split is 38% front and 62% rear under normal operation. Once there is wheel spin, the power can flow 100% to either axle.

    Under normal operation, it is equal left to right. As paisan mentioned there is a limited slip differential that allows a left/right power split at the rear axle - at least for the '01 & '02 models.

    For the '03 and '04 models Stabilitrack was made standard and since the that system controls the power split electronically, the limited split differential was omitted.
  • paisanpaisan Posts: 21,181
    Stabilitrack would then apply a brake to a spinning wheel front or rear and force power to the opposite wheel on any given axle. I'm not a big fan of this for off-roading, however on-road it works well, essentially giving you a F/R LSD as well as a center LSD so it will put power tow hichever wheel is most grip.

    I like that 40/60 split good # to know.

    -mike
  • That helps alot - we won't do much off-roading except to pull into campgrounds.

    Now all I have to do is convince my wife the AWD amd nicer interior are worth the slight premium over the standard SLT.
  • If the owner of a Silver Birch (I think) D-XL with VA tags JLP-8887 is on the forum, I was behind you on the NJT tonigth and have questions about your video system.

    What size was the screen for the rear seat passengers, and how is the view out the rear view mirror with it down?
    Can the headrest monitor display a separate source (assming players)?
    Where was the system purchased/installed?
    Cost (if you don't mind)?
    Where did you mount the DVD player?

    We're close on a purchase of a similar vehicle and can't decide between the factory system and an after market installation.

    IF you'd prefer to answer via email, let me know and I'll pass mine along.

    THANKS!!!

    I haven't been on the Jersey Turnpike in a few years and I don't have Va tags, but I think I can give you some information.
    I just purchased a Yukon XL with all the options I wanted at the price I wanted, but with no DVD. The dealer installed a Delphi system which is identical to the factory Panasonic with regard to features and fitment. This unit has an 8" screen, which when deployed obscures the center third of the upper half of the rear window. The 8" unit is $900, but a 10.2" is available for $1200. I'm not sure what size the factory-installed Panasonic comes in. The 8" screen is large enough to be viewed from the third row, and any larger would probably block too much of the drivers' rear view. It plays DVDs, CDs, MP3s, has RCA and S-video jacks, includes two wireless headphone sets, and transmits its signal to the headset via FM frequency if use of the vehicles speakers is desired. Otherwise it can transmit to the headphones while the driver listens to something else.

    Hey Tireguy, good to see you checking in again. Sounds like you got a killer deal on your Yukon XL. Congrats!

    Only now I'm seeking information more than giving it out. I should probably change my handle since I haven't worked in a tire shop for over four years. Now the only time I get greasy fingernails is when I preflight my helicopter before going flying.
    I fell in love with the big GM suvs seeing all the hotshots cruising around in them in Iraq, and when I got home I couldn't believe the deals on the '04 leftovers. Turns out they're equally suited for hauling either dignitaries with their armed posse or kids and dogs.

  • Our 2002 GMC Yukon XL just suffered catastrophic transmission failure and requires total replacement. The car has 67,000 miles on it, 7,000 miles out of warranty. This is my wife's car and she has made comments about the transmission, almost since day one. The dealer has two instances of her complaining about the transmission (at 30,000 & 42,000 miles), but other things were fixed. It died yesterday and the dealer wants $3,500. We feel like we complained about it enough that it should have been looked in to. GM Corp said it was a bad part and offered us $500 of help. What should we do?
  • Given that there were 2 prior complaints, they should do more. My trans failed on my Denali XL at 17K, so it was full warranty, no questions asked. Mine wouldn't move in any gear after the failure and had to be brought in on a flatbed.
  • Well, new update from GM...

    They called back this afternoon and offered to pay for half of the repair and that the reapir would not be marked up, so we are looking at paying approx. $1,200 with a new 5yr/30K warranty on the new trans...

    Would you accept this and forget about pushing for more, or small claims court?

    Thanks!

    paisan--my previous post was referring to the fact that the AWD setup in the Denali is (was? dunno if there were some minor changes made in '04 but probably not) is not the same as that found in the AWD Yukon.

    And yes, GMC offers an AWD non-Denali Yukon--at least they did for '03; the sticker in the engine bay says all-wheel drive but I was told the setup is technically more like full-time 4WD. Another way you can tell that the two are not identical--at least in function--is that the Yukon full-time 4WD offers a 4-LO gear, whereas (current) NBS Denalis don't have 4-LO.

    In any case it is the distinction between the two aforementioned AWD setups I was talking about.
