Shake or Vibration Issues

[Silverado-Hareek]

WELL........

 

I thought I got lucky, however now with 1,000 miles my truck has developed the "shake". It is silky smooth up to about 72 mph and then bam it starts shaking. It seems to be worse some times more than others but it is the worst around 74-77 mph. It seems to get worse the faster I go all the way up through 80 mph.

 

I have been around tires and trucks for a long time having grown up in an auto repair shop. To me the issue feels like a tire issue. The reason I say that is because i can also feel a shimmy in the steering wheel as wheel as an overall shake in the truck. I trued and balanced my Goodyear SRAs but still noticed a slight hop on the balance machine.

 

Going to the dealer tomorrow morning to see what they can do for me. They mentioned that they have had this issue on a few of the trucks so it makes me somewhat optimistic about this.

 

I can promise you one thing, there is NO way this shake can be considered "normal operation"

 

This is pretty much exactly what my truck does and I think it's the tires as well. I'm just too cheap to buy new ones. It goes away in the summer time when things get warm and the rubber loosens up more....that's what I've determined anyway. The vibration started to come back now in the winter. If it's super cold like 30 or less I don't really notice anything and when it's hot in the summer I don't notice anything. 40-60 degrees F seems to be the bad zone for temperature. I think it's a function of s****y tires and very stiff suspension.

Hey Guys,

I had the truck in auto 4wd today in a little bit of snow and noticed my 45-55mph vibration was no longer noticeable. It has improved sense I installed the new LT tires but still have the 45-55 mph vibration. it is most noticeable when im slowing down. Anyone think it might be a front axle issue? Just a thought

I was wondering that same thing today. I had it in auto 4wd with the snow also and I kept noticing the vibration on the freeway. More so than other days. I tried switching between auto 4wd and 2wd to see if I could notice a difference and I could not. But I don't know exactly how the autotrac system works with disengaging the front on the fly while rolling down the road so maybe a bad test.

This is the point I was trying to make 19 posts ago...You are not cheap,You shouldn't have to spend money on new tires for new trucks. Or you shouldn't have to spend big money to make the headlights better . I believe GM outkicked their coverage on the design..I just read an interview from Anita Burke chief engineer of GM midsize trucks says " customers want refinement, good handling and a comfortable, noise-and-vibration free ride" Not happening with junk oem tires

Part of me wishes I never stumbled upon this thread and was just obliviously and rhythmically vibrating down the road jiving to my stereo without a care in the world unaware that the cause of my shaking was due to an unexplainable underlying issue of my trucks design. Unfortunately that's not the case.

 

I'm fairly certain it's not my tires fault. They are Toyo Open Country AT2's which I'm not sure if you guys on here consider these a sh**y brand but I really like them and with less than 4000 miles on them I had the dealer swap them off my 2005 I was trading in and put them on my new 2014. My 2005 did not vibrate with these tires.

 

I agree that I dont think we should have to buy new tires for a brand new expensive truck but the reality is every new vehicle I've ever bought I thought had sh**y tires on them and I've struggled with the decision to ride them out for 2-3 years and have to look at the darm things everyday or just bit the financial bullet and buy new ones I liked. I lucked out this time being able to swap.

There is a lot more junk parts on these trucks than just tires.

Advice? Yes. Keep at it if you arent satisfied. Dont let them buffalo you. File a complaint with BBB Autoline and follow through. Send GM a certified letter ASAP and offer a Final Repair Attempt. Templates are available online for what info that letter needs to include. Contact a Lemon Law attorney and get some free advice. My Lemon Law attorney is Alex Simanovsky and he does great work.

 

Yes. The buyback offer letter from GM arrived today.

What is the proper address to send the certified final repair letter to GM?

I don't have the address with me, but there are two addresses in your warranty book to inform GM in writing of warranty complaints. One is for CA, the other is for outside CA.

well to speak purely to those who think tires are the problem, if you look at your tires there is a red dot on the tire by the rim. that red mark is the heavy spot of the tire and is marked clearly so it can be mounted exactly opposite of the valve stem . the reason for this is the valve stem adds a tiny extra weight to the rim like a balancing weight would and so to cancel this out you put the red dot on the opposite side from the valve stem. it doesn't have to be perfect but the closer it is the more "in balance" the tire is on the rim before you balance it. having this red dot aligned correctly can make a huge difference in how much weight each tire needs so check out the ones on your truck, on mine 3 out of 4 are on the valve stem side (meaning the tire needs a lot more balancing weights) and the fourth is about a 3rd of the way away from the valve stem.

 

bottom line is the tires are all put on the rims incorrectly from the start so I think this is where the tire issues come from in a small part.

 

beyond that yes they are still crappy tires and yes tires might reduce vibrations to an acceptable level for some but they don't solve them.

Thanks, I found the address in the owners manual, toward the back. Will be sending this certified last chance repair letter today to Chevrolet Motor Division. I also had to open a new BBB case as they didn't send me the complaint packet in the mail, and so I was never able to send that information back to them.

 

I did fax them all of my service repair documents yesterday and informed them that I am still pursuing my case.

Well here I am on the same boat as everyone else. I have decided to start a website dedicated to this issue. Maybe if the push is kept up there will be a global recall. I know this is wishful thinking but why not try. I already had all the resources in place.

Here is little follow up from today.

 

I arrived at the dealer and told them my problem, they were very open and honest about the problem. They said I am not the first one and they have had many trucks in for the same thing. They said that some are tires and some are caused by other things but they assured me that it would get fixed.

 

They road force balanced all of my tires and said 1 obviously needed to be replaced and possibly 2. After the RF balance, we test drove it and I would say the problem I had was about 70% better (this was still with 1 or 2 bad tires). During the ride the mechanic was very honest and said that he has done this with a lot of trucks. He said that the majority of the time it's the tires and the Goodyear SRAs are complete junk. He said that even though they can road force all of them, until you replace the tires you will always have somewhat of a shake (just to what degree).

 

That being said, they didn't have time to mount the new tires and try them out so i left my truck. They also said that they wanted it to be vibration free before they gave it back to me. I will find out more tomorrow but it sounds like they are willing to do whatever it takes to fix the problem.

Cool didn't know there is one.

Also, I must add....

 

I drove a 2014 Silverado DC 2wd 6 cylinder home and it was smooth as glass all the way to 80 mph. It had Bridgestone Duelers on it, no Goodyear SRAs.
