    I'm the latest victim of busted engine mounts

    In my case I was hearing and feeling a bad clunk every time I pulled away from a stop. The slip joint issue is similar bur far less severe. And the true test is to pop open the hood, have someone stand alongside the truck, the with your foot firmly on the brake hit the gas pedal quickly for a...

    I'm the latest victim of busted engine mounts

    Update- all done. 10.8 hours of labor, that's by the book. I stopped by the dealership while they were doing the work, and there's no possible way to change the mount without dropping everything down. I'm used to working on race cars at the track, and always trying to find a quicker way to make...

    I'm the latest victim of busted engine mounts

    Got clarification from my tech yesterday. $800 is for both sides, and includes the synthetic oil change I wanted too. And includes our insane 7.75% IL sales tax. And yes, the 5.3 can be done without dropping the diff, the 6.2 needs diff and xmember dropped

    I'm the latest victim of busted engine mounts

    I trust my dealer tech, he's never done me wrong. He said he does one of the NNBS mounts a week at the dealership and on the 6.2 with the full time AWD it's more work than in a 5.3 Yukon with the 4WD system. I checked with the tech that does other work on our other cars and he said he can't get...

    I'm the latest victim of busted engine mounts

    Passenger side was replaced at just under 50,000 but warranty wouldn't pay to do both sides. So naturally, now that I'm out of warranty by time, but only 71,000 miles, the driver's side is busted. So bad I'm borrowing a Tahoe from a friend to tow my race trailer this weekend so I don't...

    MTX Thunderform or JL Stealthbox center console subwoofer

    Any idea if it works with the rear A/C? MTX and JL do not.

    OEM Z55 Autoride Struts and Shocks

    Just towed my 7,000 lb trailer 800 miles with the Arnott Bilsteins. Fabulous, far better than the OE shocks. Even when we hit 30 mph crosswinds which blew the trailer around, the rear of the Denali was nicely planted. For the same $$ as buying OE replacements, the Arnott are remanufactured...

    Arnott Bilstein self leveling rear shocks rock!!

    Their list is $230 per corner, though they were kind enough to extend me a discount since I'm in the industry. Towed my trailer to the track on Monday and it was fantastic. Air bags pumped up nice and fast, and the towing stability was great even at 75 on downhills runs. I'm pleased. Racing...

    Arnott Bilstein self leveling rear shocks rock!!

    The rear self leveling electronic shocks in my Denali finally crapped out. First it was the electronic functionality, then more recently the air bags started to leak. And of course the GM extended warranty doesn't cover shocks (or power steering hoses, or bad XM radio module). so when I found...

    Rear air bag shot- need a new drier when fixing?

    The left rear electronic, self leveling shock on my Denali finally quit. First the electronics quit but no big deal on that. But now the air bag on that side is shot too. Hooked up my trailer a week ago and the pump ran for a good 30 seconds without shutting off so I yanked the fuse, didn't...

    Better Performance on E85?

    In my 6.2 I've tried E85 and while it made a slight bit more power my fuel economy was off more than 2mpg. And I tried E85 once when pulling my 7000# trailer on one long pull and sure it felt a slight bit more responsive but my fuel economy dropped from my typical 8-8.5 mpg (on premium) to 6...

    OEM Z55 Autoride Struts and Shocks

    Check out Arnott, they remanufacture the OE electronic shocks, as well as give a lifetime warranty. I think the rear self leveling electonic shocks on my Denali are history, plan to order a pair from Arnott, just can't decide if I want the OE style or get their custom made Bilstein shocks with...

    which gears would you go with in my case ??

    Something's wrong. 1700 at 70 in 4th gear and it won't tow? Friends use their '07 & '08 Tahoes to pull 4500 lb race car trailers all the time and they all use 3rd gear. 4th is too far off the torque curve to work well. You need to be in the 2400-2800 rpm range to pull any major weight. Going...

    6.2 Exhaust Help

    On my '09 when I removed the rear resonator the drone inside was horrible, especially when towing my trailer where pulling at 70 in 5th gear put the engine in a rev range that was the worst for the drone. Put the resonator back on and left it there. Interestingly a friend with an '09 Denali XL...

    Installed flowmaster now sluggish at freeway speeds?

    I had the same thing happen in the past with a V8 BMW X5 I had. Replaced the stock exhaust which was true duals from the cat back with a pair of small Magnaflow mufflers that "should" have flowed much better than the restrictive stock big mufflers. But I lost so much mid range torque that I had...

    towing hitch.

    I use a 5.5" drop on the adjustable trunion with my Reese Dual Cam sway control for the race trailer. I've used a 4" drop with a UHaul trailer and it rode nose high. And I use a 6" drop with a motorcycle trailer I occasionally borrow. These NNBS vehicles with the receiver hidden in the...

    Service Suspension System

    Got the Service Suspension System failure today while towing my trailer. Pump still works just fine, and no codes. About to haul the race car trailer to Alabama from Chicago and definitely don't want to have a problem on the way. But with my Reese DualCam weight distributing system it tows just...

    Rainex wipers are lousy

    I've always run the Bosch Icon wipers and have been really happy with them. Decided it was time to put new wipers on, and my local Advance store was out. So I tried the Rainex wipers. Big mistake. The float off the windshield at 75 mph and only clear half the windshield. So in the garbage they...

    Check Engine Light

    I did hit the onstar button for the first time to have them pull the code. best hey could tell me was that it was "Ignition Related" and that's all. Bought a scanner myself (why can't anyone offer software for a laptop like I"ve had for other cars and SUV's) and found the code was the knock...

    Did not know that. I'll call and ask. But is that different from pulling the status on their website?

    Check Engine Light

    I figured it had to be something unrelated to the oil service, as coincidental as it might be. Guess I have to get used to a CEL every 6 months on this Denali, that's what it's been so far. And every failure has been emissions related which isn't covered under the 5/100 powertrain and has been a...

    Check Engine Light

    So how reliable is the Onstar diagnostics? I got a CEL while driving home last night. Looked up in my Onstar diagnostics and it said no issues found, all Green. The only item is that my oil life hit 0% this week. Is it possible that hitting 0% triggers a CEL and prevents the remote start...

    Alphatherm

    I added the Alphatherm part to my '09 Denali that hadn't come equipped, and I have to tell you that it's been the second best accessory this horrible winter, second only to my heated steering wheel. I absolutely love the fact that after about 30 seconds I have heated water to clear the frost or...

    Anybody disable the wiper extra sweep after running washers?

    I'd love to find a way to disable the extra delayed sweep of the wipers after running the washers. Invariably the windshield is dry and the wipers just drag against the windshield. Has anyone figured out how to do this?
