Guessing that's why you disposed of 50K of it on a vibrator.

lol, maybe i'm just lucky but my 2014 and current 2016 silverado have been vibrator free....2014 had 58,000 miles when i traded it in and my 2016 currently has 20,000 miles.....and i definitely did not pay $50,000 :)

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

In my particular case I noticed the bed was shimmying while driving and with no help I took my driveshaft to a specialist shop who found it was not only out of balance at the rear but not even straight. That managed to take the wheel hopping issue from the rear away but its now coming from somewhere in the front through the steering wheel and pedals. Feels like trans of front diff issues.

 

I notice you have aftermarket wheels and tires with a possible level kit? I had Mazzulla uppers, Fox coilovers and rears, wheels and tires and they straight up turned me away FYI stating that my warranty was void and any vibrations felt were because of the aftermarket parts. I talked to GM corporate and they agreed that even changing wheels and tires that my 100,000 mile 5 year powertrain warranty was no longer good. I had asked if by their standards that I would have to keep the OE tires for 100,000 miles and the guy told me yes. That's when I laughed and realized that I would receive no help at all.

 

My advice would be to put on your OE equipment before going down the never ending road just incase they decide to put a note on the paper work that you modified your truck or just turn you away wasting your time.

 

He is completely correct, as soon as they see aftermarket parts you are done for! I went through the same thing, spent a lot of money on no warranty voiding upgrades and was told I still voided my warranty and would have to pay out of pocket for any repairs associated with the vibration issue. What did I install you ask? Wheels and tires and cat back dual exhaust, neither of which at any other manufacturers dealership will void your warranty.

My advice is the same as most, get rid of it while you can and hope the dealer you take it to doesn't ask if it has the "Chevy shake"

Magnuson Moss act put's the onus on the manufacture to prove you're aftermarket parts caused whatever issue they are trying not to warranty. In the case of the vibrations even though after market wheels and tires are not the cause it's hard to argue that they have to address the situation without having the factory wheels on the truck it's just an easy out for them to not touch your truck.

I had vibration at 35-45 and 73-80 did a level kit and body lift vibration stayed did bigger tires vibration stayed did new bilsteins level struts and another alignment and no more vibration at 73-80 and I rarely get a vibration at 35-45

Interesting. So, which of those last 3 steps do you think solved the 73-80 mph vibration; the Bilstein shocks, the level struts, or the alignment?

 

BTW, pardon my ignorance, but what are "level struts"?

level struts, are replacement struts that are longer than factory to level the front end with the rear. Search rancho quick lifts, they are a full replacement spring and everything. The bilsteins are just the strut itself, you disassemble your factory assembly and replace the strut with a longer one and reuse your spring and top hat and hardware. The end result is something about 3/4-1" longer than OEM raising the front end about 2" give or take.

Got it. Thanks. I didn't realize that these new trucks use a strut like a car. Was thinking older style with separate shock and coil spring/a-arms.

So, what is interesting about the levelling struts is that raising the front end and eliminating the factory rake would affect the front end geometry ever so slightly. I'm struggling for a theory on how that could be related to the shake/vibration, but interesting nonetheless. Must be something to it.

Got a call from the GM advisor and was asked about the truck, told him it's still the same. Then he told me that I have the wrong tires on it as they are ATs from Bridgestone. I advised him that the GM specs for my truck called for ATs not those cheap Goodyear all seasons. And when I first got the truck it had the Goodyears and it vibrated then. I also told him that these tires were put on by the dealer and that according to GM requirements they are considered OEM and that's the reason I went with them. I told him that if GM wants to buy new tires, have at it. Also told him I was going to be in a different state for awhile, surprisingly, he told me that to call him and he would arrange for me to go to a GMC dealer where I am..

The story continues, ....a different brand is looking better and better..

Total up how many hours you spend, trying to deal with this issue. The phone calls, the trips to the dealer the searches - posting on the internet and the time talking to friends/family/co-workers about it. Then decide how much your time is worth. Are other brands perfect, NO. But this is a known issue and GM has decided not to resolve it. In the 18 months since I opted out the only time I spend on this subject is reading this thread, it's kind of like a train wreck. I just can't stop looking :(

They don't. The correct term is coil over shock.

Leveling mine with a set of Fox coil overs and a 1" block in the back eliminated the 35-50 vibration in mine. I still have a minor 75 vibe that isn't always there. I have wondered a couple times if some of this is compounded by aero. Maybe even to the point that air density effects things. Just a thought though. I have a feeling tire temp and pressure is more likely it.

Taking mine in Monday. Just what is force balancing?

 

Do dealerships have the ability to true up out of round tires?

Just an FYI it is not your tires. Its the GMs way to go the cheapest route to say they are trying to fix it. I tried 3 different rim/tire sets with the same vibrations and put my OEs on another truck and it was smooth as glass.

Yeah there can't be that many bad tires or incorrect ly balanced but it's the first step of the process.

There maybe some truth to this! I am on my second batch of "GM Certified" tires and still no solution.

 

So I'm up to the following parts.

 

Tires x 3 or 4 sets

Right and left rear axle

Ring and pinion

Right front wheel hub

New wheels

Steering bushings

 

I still don't have possession of my truck. Over 30days straight.

      OCI, not when but why?

      By Chuck FB · Posted

      I had skimmed through that article when you posted the link and honestly I felt rather defeated in a sense and realized that all these years in changing oil that in fact putting in what I was told was a good quality oil was probably not filtered as well as it should be although the filter put on the engine would be what ( as long as it never went into bypass mode ) would be the final filtering of the new oil that the engine components would first see, but then the filtering media itself is not up to par to what is ideal because a full flow filter would be too restrictive to filter fine enough for the engines best outcome in the long run. Only one of our tractors over the years which was a Versatile with a 855 Cummins had a separate bypass filter, some engine manufacturers did spec a partial bypass system within the main oil filter but I don't believe any other trucks or equipment I was servicing used such a filter. No doubt a product like the Amsoil bypass system is of benefit as long as nothing goes sideways with the extra plumbing and filter such as a rupture/leak that could cause the oil to pump out of the engine ( yes that Versatile had a remote canister with hoses routed to it as well ). With the idiot egr system on a diesel and as a result forcing a lot more soot into the oil, that certainly isn't helping the diesel engines cause or as you pointed out the GDI engine issue with creating more soot and aside from having a fancy secondary filtering system, changing the oil more often helping lower the total soot load.     So oil manufacturing and the end product is not something one can control and I wonder if there are specs on what various oil packaging companies produce in particle count or size. As to the filtering, if the OEM is not designing a filter size and spec that is really what it could be, they too are short changing the end user and so what is the answer. Of course as you say the oil side can only do so much if the air side isn't keeping up its end of the picture and air filters are only so efficient and if in a dusty environment such as farm or construction or driving gravel roads there is a lot of dirt to filter out and some of that ends up into the air stream.    Of course the irony in places like where I am where they dump the salt on the highways but also will mix in some calcium or outright pure calcium for problem road area's, or using calcium as dust control on gravel roads, the vehicle that gets used in that environment may rust out before a properly engineered engine and maintenance finally wears out so one has to face that reality in the rust belt.

      Oil Change

      By Erfar · Posted

      have you stuck with dealer oil changes since then? I made the same switch after getting tired of crawling around under the truck, but I’ve found some dealers are way better than others about getting you in quickly. Curious if yours has been good about scheduling or if you’ve had to look elsewhere for quicker turnaround.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thank you.   I am set on a 3.0 Duramax as my previous truck with a Ford Ecoboost had just as many, if not more, "common" issues.  Cam phasers, timing chain issues, 10-speed valve body and CDF drum, emissions issues, etc.  So I figured, why not get 2x the fuel mileage (these things got 27+mpg on every mixed city/highway test drive I put them through) and better towing capability with resale value to boot?   My minimum, shortest trip will be 50 miles 1-way and I regularly go out of state with a travel trailer.  I'm planning on using this for a marketing/event promotion business also, which would require regular towing of trailers for bands, DJs, sound and lighting gear, along with my personal camera gear for filming events.   Looked at other trucks in the $30k+ price range but the issues seem to be everywhere, plus too many with gaudy mods.  I'm literally sticking with RWD trucks because they tend to be actually used as trucks, vs. the 4x4 models I've seen with unsafe lifts, huge tires, and general mods that would affect reliability (I'm wondering if some of them were tuned, hence the aggressive throttle response and hard shifting).   So my goal is to find a stock, 3.0 with 1 or 2 owners, in good physical condition, and decently well maintained.  Can't seem to find that up here, everything in the $27-30k range has had multiple owners, smoke smell, issues, or body damage.  Or the ridiculously modified trucks with 80k miles for under $27k but lots of problems...

      That’s pretty tough Grumpy. I reread the previous few posts. They all reference oil changes. Much like your last thread. In my humble opinion it keeps things interesting.
