    Driveline and Tire vibration , my '11 brand new HD diesel

    Ya, it sucks!

    As some know, I bought a new '11 ccab, shortbox, 2wd, HD diesel.

    The moment I drove it off the lot, it had a bad tire vibration, so bad that I couldn't have a soda in the holder without it spilling out.
    I should have turned around that day and say NO!
    Well, when I got home, I called and they said since the trucks sit for so long on the lot, the tires can get flat spots, but drive it for about 300miles and if it doesn't get better, bring it in. Well, 300 terrible miles and I call, they say, oh it needs 700miles. Well, BS, at 500miles I drop it off and it's determined that all four tires are square, so all four get replaced with new ones. Drove it off the lot and the rears are still vibrating.
    Take it back the following week and the rears are changed again for new ones.
    Now that most of the vibration is handled, I noticed an issue with a carrier bearing vibration. GM has a TSB out for this. SO, take it back in and get a new assembly, just not the carrier, they replaced the entire shaft(s) and bearing. That one wasn't good enough, so the same day they replaced it with one off the lot.
    Now it's better, but still not acceptable. So I take it over to driveshaft specialists where they determine it has too many weights on it and they high speed balance it.
    It's better, but still there.
    Dropped it off today for more tire vibration and the dreaded 45mph driveline vibration.
    Spent 2 hours there test driving other HD's that might possibly meet my expectation, well, all the other HD's vibrated too, lol.
    SO, truck is still there getting handled.

    any input guys????

    their balancing machine measures wheel runout and tire roundness, so I'm assuming they did this.
    What about the tsb for the 2011, extcab and crewcab shortbox only?

    thanks for any input,
    allen

    If they're testing runout, they are.

    I honestly don't know, if its brand new and completely stock, say f it and be that pain in the ass customer. I remember one HD when I was at GM. Brand new, could not get the vibrations out and GM bought it back. This would've been an '09 model though. And it was a RCLB.

    Dad's 2011 doesn't do it, again though RCLB.

    Most (one LOL) of the complaint I have seen was a Denali HD. Someone that came out of a GMT800. The 2011+ HD is supposed to ride better with the stiffer frame and hydraulic body mounts and that works for most people but for the ones that are not satisfied.....they are really not satisfied. I made a 2012 3500 dually ready today with a $62K tag. OUCH! Better ride like a one ton, huh?

    I don't know what it could be, seems they are checking and taking all the measures to get it to smooth out.

    My 2011 isn't doing it and neither did my 2008.

    Only difference is both my trucks have been CCSB 4x4s.
    2013 EC Silverado aka redruM (Just a couple bolt ons.)
    2007 RC Silverado aka ?
    1998 Trans AM aka Red Dragon

    Hmm I dunno bout these new ones, kb is it a z714x4 or 4x4? Maybe its a weight issue... Maybe the better suspension was tested by gm on the 4x4 versions only with no vibrations... I could see a could hundred pounds extra making it ride lil smootber in this case cause its a hd suspension... I hope you get it figured out since its brand new... I believe I saw the airsoft tire balancing on here and since then googled it a time or too and seems to work well!! Actually om positive it was on here and maybe mic can recall the thread too because he mentioned his experience with balancing the centerlines I believe it was... Im goin to txt the guy I got the wheels for kb from tomm and see if he has any issues...
