    NNBS Yukon Spec-D projector beam headlights- never used

    I picked these Spec-D lights up to try in my Denali because I always thought the OE headlights were horrible. Never had the time to install them and traded it a week ago for a new turbodiesel SUV. So these need to go. Spec-D, use H1 bulbs (included), separate low and high beams, which should be...

    Bye bye Denali.....

    I've wanted a turbodiesel SUV for several years, too bad GM won't give us what Jeep, BMW, VW, Audi, Mercedes, Porsche will. Came close to a VW Touareg turbodiesel but with the impending recall I chose to go the Jeep route. Didn't need the big SUV size anymore, or the 13 mpg. Jeep fit the need...

    Bye bye Denali.....

    While I've loved owning my '09 Denali, once I got over 90K miles it started getting really expensive to repair everything that's gone bad. Front diff carrier bearings, rear air shocks and compressor, nav head unit. And just 3 weeks ago at 104K miles the transfer case needed the drive chain and...

    Autoride question....Delco or Arnotts?

    I'd go Arnott. The company is great to deal with and they make a product that's first rate. I first bought their parts when the air bags on my 2002 Audi needed replacing and the Arnott shocks were half the factory parts. Then in a Mercedes I had. Now I have the Arnott rear self leveling shocks...

    5.3 swap for a 6.0 2012 tahoe

    There are several differences between a Denali and a Tahoe other than just the engine. Would need the full 6.2 exhaust which is larger diameter. The trans is the 6L90 where the Tahoe is a 6L80, both 6 speed automatics but the L90 is beefier. Different transfer case, I'm told the reason the...

    07 Tahoe LTZ Air Compressor

    Just did mine on Saturday, pretty easy to do. I used the Arnott compressor and new dryer, I wouldn't go with a no-name product or you'll likely be doing it again soon. The compressor lives in a harsh environment. The Arnott comes with new desiccant to rebuild the dryer- essential if you'd driven...

    Bleeding Brakes

    I have always used a Motive Power Bleeder for all my cars, have the GM adapter to do my Denali. Do my brakes every two years, with good ATE SL brake fluid. Using the Motive makes bleeding a one person job, just connect the jug with a liter of brake fluid to the top of the master cylinder...

    Throttle Adaptation- anyone try this?

    In my previous Bosch FI equipped Audi and BMW vehicles you could perform a throttle adaptation that essentially reset what the electronic throttle learned, in other words get rid of its bad habits. Tried it on my Denali last week and it worked. My part throttle shifts had become a bit harsh...

    LT tire recommendations for my tow vehicle.

    I tow quite extensively with my Denali, never had a problem with the OE Bridgestones. With the proper weight distributing hitch, and 36psi in the rear tires I'm extremely pleased with the way the Denali handles the trailer. I will say that I did add a Hellwig 3 position adjustable rear sway...

    2010 Chevy Tahoe Disc Brakes

    I tow a 6,500 lb trailer many times a summer, including up and over the Appalachian Mountains. I made a few simple but very effective changes to the stock brake system to handle the heat and resist fade: Centric StopTech (formerly StopTech Powerslot) slotted front rotors, not much more expensive...

    Wheel Bearings

    They're both customers of mine- Advance and Rock- so either way I'm still doing business with someone who buys my parts, I'll only buy from someone who buys from me. But when it's my wallet paying for parts I find the best deal among those customers.

    Wheel Bearings

    Just call the Advance toll free number and tell them to look at the Rock price. They'll authorize the price match. And yes you're right, Advance was exactly double the Rock price for the same damn part number. Two minutes invested on the phone saved me $60 per side.

    Wheel Bearings

    My local Advance Auto Parts had the Timken in stock and matched the Rock price.

    Wipers have been really slow in our recent cold weather

    As a followup- I replaced the wiper transmission and motor as an assembly from the dealer. Had ordered just the transmission assembly from RockAuto and they sent the wrong part. With a bitter cold weekend approaching I didn't want to risk not having working wipers so bought the full assemble...

    Wipers have been really slow in our recent cold weather

    Apparently very common on the pickups which use the same wiper motor and mechanism.

    Air/no-air suspension on Yukon XL for pulling Toy Hauler?

    Which is why I also have a GMC 2500HD Denali with a Duramax/Allison. Where the Yukon Denali struggles to pull mountains at 50mph and 7mpg, the Duramax pulls every grade at 75 with ease and gets 15mpg doing it. But for more local races, <100 miles away, when I need the seating of the SUV with...

    Wipers have been really slow in our recent cold weather

    This past weekend when temps dropped into the single digits my wipers moved very slowly, barely making a full pass in 20 seconds. Pulled it inside on of my heated loading docks here at my business Monday and after that the wipers worked pretty normally. Until this morning, now -2 when I got...

    Air/no-air suspension on Yukon XL for pulling Toy Hauler?

    Remember these tow ratings are WITH weight distributing, not dead weight. I tow a 24' v-nose race car trailer probably 10,000 miles a year with my 6.2L Denali. Total towed weight, certified on a Cat scale fully loaded, is 6,700 lbs with a 900lb tongue weight. I use a Reese DualCam weight...

    Bridgestone Dueler Vibration?

    I put new Duelers on about 10,000 miles ago. Developed a vibration shortly after that. My tire store rebalanced them a couple times, then finally Road Forced them. Two of the tires were way out of spec and had to be replaced. Sadly my original tires lasted almost 50,000 miles, the second set...

    Transmission Oil Cooler?

    Take a look at my post from a year or so ago. I also tow 6700# and was seeing trans temps in the 225 range when pulling hills. Installed a Derali cooler in series with the stock cooler so I now have 2 up there. Trans temps rarely get above 195 when towing , usually in the 185-190 range...

    Tow Haul Mode question

    Can't speak for your 2003, but in my '09 there are a number of things that Tow-Haul mode does, and these I got directly from a GM engineer. Holds gears longer before upshifting, so the engine doesn't lug down. And it keeps the transmission from hunting between gears which builds up heat in the...

    Improve Towing

    How heavy is the travel trailer, and what's the tongue weight? Most people who tow travel trailer use a weight distributing setup to properly redistribute the tongue weight rather than just rely on the shocks. Personally I use the Reese Dual-Cam system which is weight distributing and sway...

    E85 fuel!

    I'd tried E85 at one point when towing, figured the extra power would be beneficial. But since my Denali requires 93 octane the difference in power was there but very slight. However my towing mileage dropped close to 2 mpg, I was having to stop every 120 miles to refill which is a pain when...
