Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

Saddly I have now developed the dreaded vibration that starts at exactly 20 mph and stops exactly at 30 mph . Doesn't vibrate at any other speed very strange . You can feel it in the steering wheel and gas peddle also a little on the floor Board . It feels like your on a pebbled street or rumble strip . Anyway I will be taking it in for service in the near future . Love this truck but the vibration is very annoying . Didnt really notice it for a while but now that I have I don't enjoy my truck as much . Freeway speeds are smooth but city driving is when I'm in and out of the vibrating mph . Accelerating you don't feel it but steady speed anywhere between 20 and 30 mph or stopping for a light it does it . Hope they have a fix : (

Ok, so this coming Monday will mark the 4th consecutive week that my brand new truck will have been in the service department. If they do not call this week, does that mean that I am eligible for the lemon law in the state of Tennessee? I heard somewhere that 30 days is the mark.

Are they gold plating it?

The dealership rebalanced my Goodyear SR-A tires 29 days since the last time they did it, at which time they replaced one that would not force balance below 15lbs. Well, they said they matched balanced one that was off, and the other three were only generating 4-6lbs of force. Now the truck vibrates more.

 

Time to go find a good tire shop...

Maybe it is time to trade for a vibrating 2016 model? Are they out yet?

 

As I said several times before, road force variation, even if zero, does not guarantee good wheel balance. Proper wheel balancing does. So once again, measuring road force variation and correcting wheel imbalance are two different parameters. Hunter 9700 wheel balancer, first measures the road force variation (if that option is selected by the operator), then wheel imbalance. If the road force variation is excessive, the machine will flag it. Low force variation means the tire is very little out of round. It does not mean the wheel is properly balanced. If the machine is improperly calibrated or the wheel is incorrectly mounted, chances are they balanced the wheels wrong. Way wrong. Possibly they all are out by as much as 1 ounce. This will cause very unpleasant vibration at high speeds. I have seen this before. More than once.

 

Perhaps the main reason for a bad balancing job is selection of an improper size cone to center the wheel on the machine. If you use a cone that is too large and catches on the outer lip of the center hole, the wheel will not be properly centered. A combination of a proper fitting spring loaded cone on the inside of the wheel and a good quality wheel lug adapter on the outside of the wheel is the best way to mount a wheel on the machine.

Or maybe it's not a tire issue....

 

It vibrated after I first got it. They replaced a tire and forced balanced all 4. It no longer vibrated. Then a slight vibration came back around 55mph. They checked all four and messed with one. Now its worse than when it went in the day before.

 

So either we have a heck of a coincidence on something else coming into play, or they didn't do it right. My money is on the later based on the experience so far. Worst case scenario is I dump these crap Goodyears for Michelins and then rule out tires.

As you said, time to find a competent tire shop.

Hi reporting to what I believe is the correct thread for my issue:

 

From what I'm reading there is not much of a solution for the vibration problem. I have 2014 6.2l with the max trailering package as I tow a 8000lb toy hauler. Truck tows great but the vibration when towing is getting worse. I'm not sure if this is the same problem as mentioned in this thread but as you can imagine when towing you put a big load on the truck - this is making the vibration bad.

 

I've already brought the truck in three times to fix problems and with only 6000 miles on it I'm disappointed to have to bring it in another time.

Has anyone looked at the transfer case? Driving along @60-65mph on a newly paved concrete tollway, going straight, I put the truck into 4 wheel drive "Auto" mode. The rumble strip vibration I have been struggling with suddenly gets much worse. When I disengage the 4 wheel "Auto" back to 2 wheel "Hi", after several miles it seems to dissipate back to a slight rumble strip vibration (felt in the steering wheel and pedal and slightly in the seat) especially at 40-50 mph.

Perhaps something in the front drive line is the source... Putting in 4 wheel "Hi" also has the same affect.. and I am going completely straight forward.

As soon as i took those shitty azz tires off my truck its been smooth as can be. Ive got 12k on it and still ridin smooth. The other day i was coming home from BPS and i decided to take the highway to see if my vibration had came back... Nope, smooth all the way to 85. I'm not saying tires will fix everyones trucks, but im sure glad i didnt screw with the dealer on my 2nd go round

      Clunk when putting truck into drive and reverse.

      By Matt Parker · Posted

      I have a 2000 Silverado 1500 LS, whenever I put it into reverse and also in drive it clunks, the truck also feels sluggish when driving. Any advice/ideas ?

      Some Assembly is Required

      By Grumpy Bear · Posted

      Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.
