Shake or Vibration Issues

[tbarn]

Escalade's,Tahoe's, Suburban's do.

Just stopped by my local tire shop to discuss some options on my new old truck. We talked about the new GM trucks and what I've been through. He said that ALL GM trucks are having this vibration issue. Some people feel it or some don't. Some don't drive above 65 or so which is where my vib started. He states that GM knows there are issues but again, won't publicly admit.

 

I'll straight up tell you, my truck does NOT vibrate.

Has anyone noticed a difference between the windows up with the ac running and having all the windows down on the highway. I've just recently noticed that At 75 mph with all windows down my truck doesn't seem to shake like it does with the windows up. Could this be an air pressure or aero issue? I also have a tonneau cover on my truck which does flutter in the wind. How many people having shaking at highway speeds do or don't have a tonneau? I think they made the rear of these trucks too light and too stiff.

Somewhere along the line I took mine off and no change. Like 1/2 way back...

I have shudder and vibration before I installed a backflip tonneau cover and no change in the vibration issues.

I just noticed wheel sensors at each side of rear axles, i wonder what their real purpose do, are they for the traction control system.

Heck this is just the first series of events. Im already past Bigfoot, Nessie, Little Green Men, the G Spot and other Urban Legends. But good luck.

Made me laugh.

I'm curious if anyone has had this issue then either lifted or lowered the truck and it went away???

Ford produces 800 - 1000 so does Dodge, and Toyota a day and their trucks don't shake, last generation GM trucks did not shake like these do!

I am not about to be force fed this bull**** we all paid good hard earned money for these trucks.

Some of us rely on these trucks for or income and spend a lot of time in them too!

So we are entitled to a response from GM, or acknowledgement that they are aware these trucks have issues and that they have not forgotten what their customers are dealing with!

I have found GM refused to do anything for me, until I got legal advise and help addressing my troubled shaking, shuddering, clunking, bad reception, moving seat, rusting frame truck.

How could they claim so many miles testing without knowledge of these problems?

What type of legal advice did you take if you don't mine me asking?

So it's been about a week since I had my 2 out of round tires replaced. The shake has gotten worse, it was a lot better a first but now it's just as bad as before I got these tires replaced. Think I am going to try something radical. There is this a product called dynabeads by this company http://www.innovativebalancing.com Apparently you put this stuff in your tire and it continuously balances the tire. Anyone ever try something like this?

It definately couldn't hurt to try, I may just give it a try. Sure would be something if this fixes the problem.

Hey all! It's been a while since my last post so here's what has happened since my new ring and pinion.

 

Vibration seemed fixed with the repair and factory wheels and tires (tested for 2 days of driving) so I put my aftermarket wheels and tires back on. Vibration again. Had them road forced. Still vibrated. Traced to one particular tire and had it replaced. Better but still vibrated. Took to another place for a another road force. Same vibration. Replaced with original wheels and tires. Still had vibration. This Friday last I picked up a 2011 2500 Denali Diesel. 30k miles on it. I am test driving it this weekend. The thing rides and drives like any truck should.

 

Noticeable differences already;

 

You can drive at hwy speeds and have a smooth ride.

You can drive at hwy speeds and have just the drivers window down without the "flutter".

The climate control doesn't blow cold air when the engine is cold. It "waits" until the engine has temp then blows.

The front headlamps don't fog over.

The electronics in the display don't lag.

The seats are more sturdy.

No constant downshift on slight acceleration. (Granted this is a diesel but still, that was annoying...)

The list goes on and on.

 

GM- You have issues with your new truck line. Own up to them. Fix the problem instead of burying your head in the sand. I loved the look of my new 2014 but I hated driving it. Literally HATED driving it. That shouldn't be.

 

I will most likely end up with this truck. I like the look and I like the drive. More truck than I need but hey, it's only money....

 

GM- If you want more info, please reach out to me in a PM. I would be happy to discuss my experiences with your new truck in more detail....

 

All the best to all that are having issues. It's no fun.

Curious as to what kind of MPG's does the 2500 get?

What type of legal advice did you take if you don't mind me asking?

I am still in a situation I can not talk freely yet, but I did contact legal advice and am following through with a fix it right now or take it back offer.

My truck has more then just a shake, it has all the issues listed in this forum including rusting frame and bad shifting and shuddering transmission.

Start with consumer lawyers they seem to understand our rights better then other avenues.

Do lodge complaints with BBB and the NHTSA concerning our shaking, under powered headlight trucks.

Remember it is the manufactures responsibility to meet the advertised warranty at time of sale, not the dealers.

So all your attention should be directed towards GM and that not all their trucks shake or have this issue as per other test drives you have taken.

So why is my truck not preforming like the others, keep note of the vin # you tested.

Document everthing, keep calm and organized.

There are several companies that sell a similar product. I think this bead balancing concept started on the big rig tires.

Found this on youtube comments on this vid

Has anyone tried this to stop or lessen the shake?

Comment from video

I took mine in twice for it. The first time they said it was normal too. I didn't buy it, so i took it in the second time . They kept my truck for like 5 days. Finally they called gm. They said to shim the right engine mount 2 most inner bolts 3mm. They did this and it work! I can't hardly feel any vibration at all. There is some, but not really noticeable, so I am happy. I don't know if you watched it or not, but I have another video on here labeled "vibration on a 2014 Chevy silverado" that shows the vibration I was having.

Look what I got today...... Interesting. I think they are watching.

[biggspell]

My rear end was replaced and I got the truck back today. They replaced the complete rear end from disks brake to disk brake. Test drove for approximately 25 miles vibration still there between 60-65 and greater. My dealers service manager who has been totally great to deal with, really didn't know what to do. He was working a GM engineer. I will be waiting for another suggestion. So far as I have noted in my previous post. The following has not worked;

RF balancing

Michelin tires

new drive shaft

 

Then they bought the truck back and I ordered another one exactly like it. LTZ, double cab, long bed, 342 rear end, v8

Complete rear end

 

I have drove two or three loaner trucks during the past 9 months all of which have this issue.
