I am a good customer to my dealer, and he took off my vibrating LS2's and put on Bridgestones on my '11 S. Denali at around 3K miles.

[Stex]

Ryun911: Hope that can fix it. What is the vibration? Steering wheel moving? Front passenger seat shaking when empty? My friend had the Eagle 20s on his 07 SLT and never mentioned a vibration/balance problem. After about 30,0000, When he did replace them with LTX M/S2, he did say it rode better and wet driving was better.

 

Let us know what they do.

 

Side note: was at my GMC dealer today and noticed most of the 2500 HDs, '14s come with Michelin LTX A/T2.

I posted this info in the "Any new 2014 Silverado owners having issues with their truck?" thread but found this thread after and feel it would be more benfeficial here:

 

After taking my truck back to the dealer Monday 12/09/13 for a vibration issue, they failed to correct the problem by rebalancing 3 of the 4 wheels. I was told by the dealer that they used a traditional balancer.

As many of you suggested, I am now sitting in the waiting room of a reputable family owned tire place in the town where I live. They only use the road force balancer for all of their balancing. After them taking the truck into the garage for 10 minutes, the tech came out to let me know how it was going. I told him the wheels were already rebalanced once from the dealership. The tech said that he can see that new weights were added to the wheels but the old weights were never removed. He felt confident that I would be good to go after he removes all the weights and rebalances. He is also checking the driveshaft. Said they recently found a dodge with a bent factory shaft with only 1000 miles.

 

The tech rebalanced the wheels removing all weights that the dealer put on. He took it up to 60MPH with no vibrations present. He said he actually had to flip (1) tire on the rim to use the least amount of weight necessary as the Road Force machine indicated. I took the truck, drove it around town and it did indeed ride better than ever! Smooth as glass!! I took it up on the highway, hit 70+MPH and the vibration is still there, though noteably not as bad. Before the truck felt like it had a left to right shimmy where if you put your head on the headrest, your eyes were unable to focus on the road. That left to right motion has subsided for the most part however the vibrations are still there and seem to now disappear around 80MPH. Thinking that maybe it was the road, I tried (3) different highways in the area with the same results on each. So to recap, the wheels were balanced on (2) different types of machines, on (2) different days by (2) different places, one of which is a very reputable family owned tire shop. I am starting to think its either the tires themself or something totally different. The reason I bought this new truck was because my old one was starting to get up there in mileage and eventually it would need some work, but hell it had over 85,000 miles on it so thats expected!

So another call to GM to update them on what was found once this independant shop balanced my wheels. They politely told me my case, though opened yesterday 12/11/2013 was closed. I asked how is the case "closed" and what was the outcome? I told the GM rep that I was never contacted by them nor did I contact GM to let them know that the vehicle was fixed properly so how could the case be closed? The GM rep told me that it wasn't his case, however he would re-open it and have the rep (who's name and extension I won't post here) contact me once she gets back in the office.

 

GM if you are reading this, can you kindly locate my old truck that I traded in, give it back to me and I will gladly give this Silverado back to you! No really i'm not kidding!!! What did I get myself into?

FUNNY YOU SAY THAT I HAVE A CASE OPEN WITH GM AND WAITING FOR A PHONE CALL FROM A (GM SPECIALIST SO WE CAN GO TEST DRIVE THE TRUCK) WHO HAS NOT CALLED .... I CALLED THE DEALER THEY SAID THEY WERE WAITING ON THE GM SPECIALIST ALSO..SO I DECIDED TO CALL GM CUSTOMER SERVICE TO CHECK ON MY CASE AND GUESS WHAT THE CASE WASE CLOSED ON 12/10/2013..SO THEY ALSO OPENNED A NEW CASE.. MY SPECIALIST THAT CLOSED THE CASE WAS AMBER ( SHE WAS NOT TO BRIGHT AND SAID GM DID NOT HAVE A FIX AND WE NEEDED TO WAIT FOR A ENGINEER ) SO NOW I HAVE A NEW SPECIALIST NAMED WAYNE... WAYNE SAID THEY WILL CONTACT ME WITHIN 24 HOURS.. I WILL KEEP EVERYONE POSTED ON A UPDATE... I THINK THIS IS OUT OF HAND AND WE NEED ANSWERS AND I ALSO WOULD LIKE GM TO PURCHASE MY TRUCK BACK.... I WANT NOTHING TO DO WITH THESE POS TRUCKS.....

 

JONATHAN OR JENNIFER PLEASE PLEASE PLEASE HELP US OUT ON WHAT IS GOING ON.....

[Arnoldthepig]

If this has already been done I do apologize in advance. Everyone with vibration issues in the 2014's post the following information.

Build Date: 07/13

Engine: 5.3

Axle Ratio: 3.08

Cab Size: Crew Cab

Bed Length: Standard Bed

Wheel Size: 20" OEM

Tire Size: 275/55R20

Tire Brand: Goodyear Eagle LS-2

Speed(s) where problem is present: Was 70+, now more noticable 75-80 range

Location where vibration is felt / seen: Felt in steering wheel & seats / vibration can be seen in water bottle in center console

IF your problem was corrected how: (2) seperate balance jobs on (2) different machines at (2) different places. Not fixed, still junk!

 

Maybe, just maybe, GM in their infinite wisdom will read this and find a common denominator. Doubtful but worth a shot.

Update: Called the dealer today to check on my truck and to tell them the loaner was just as bad, if not worse. The service guy told me that they put two more new tires (Goodyear LS2) on my truck (This makes 3 out of 4) and would drive it and see how it goes. No word yet.

 

STex: I also had these exact tires on my 07 Crew Sierra SLT with 30,000+ miles with a smooth ride.

 

Arnoldthepig: I feel a slight vibration in the steering wheel, a little more in my body and the gas pedal and the passenger seat shakes, vibration in water bottle (high frequency). Started with only vibration above 60 then more at 75-80. Now i can feel it as low as 40-45. I can feel it as low at 30 on the loaner, but worst at 80. I went as far as to use the Vibrometer app on my Android phone to track the vibration at different speeds.

 

I loved my GMC and love this truck (aside from the vibration) but if it's more than a bad lot of tires or rims, I don't want it. I refuse to spend another year suffering because these automakers will not stand behind their products.

 

I will update everyone when I get the truck back next week.

A crap load of truck payments for starters.

Called gm customer service again yesterday and my case is still open at least. I really wanted to get them to say that they are hearing about this problem form other people than just me. I have talked to 3 specialist and they claim that mine is the first time they have heard about the vibration. They had talked to the sm at the dealer I am using and he has a plan to try and fix it on my 2nd trip after the road force balance. Talked to him yesterday and he wants to keep it for a full day to mount a different set of tires and wheels to try that out.

[hvill]

Greenhead. GM IS FULL OF SHIT and they are not going to do anything about it.. I have been trying since the first time I took it in with 335 miles and now at 3800 and still no fix... Its at the dealer right now road force balancing again..lol how many times can the do that and figure out it is not the dam tires they keep insisting it is.. we are hopeless you can get a lawyer involved if you need to...which I think is our best bet........

I know this is going to look suspicious being only my third post but I wasn't sure what forum to join at first. I have noticed a shake or vibration in my new 4x4 crew 5.5 box 5.3 truck it seems to come and go and has been a pain to pin point what makes it happen. I can feel it in the steering wheel, seat and sometimes the gas petal but mostly in the steering wheel. It seems to be most noticeable going up or down hill with very light acceleration but can do it on level ground at cruise speed too. And the fun part is it doesn't always do it to make it more of a challenge to diagnose it.

Brought it to the dealer last week and I thought the mechanic was going to think I was crazy but he did feel it too which was a relief also the service writer test drove it after they balanced and rotated the tires and he said its slight, but he felt it too. We scheduled it to come in tomorrow and are opening a warranty claim. I have very little faith that its going to get fixed because of the nature of the vibration and it being so new that there probably isn't any info out there on what it could be. I really don't know what they can do tomorrow other then make phone calls. If I had to venture a guess I'm going to say its in the transmission or possibly the engine.

We also have a 2012 equinox and on the same roads there's no vibration at all.

Also I have the z71 and man does that thing ride STIFF! Every repair strip in the tar is felt hard! Anyone know if it just takes some miles to get the shocks broke in (2600 on it now)? My 04 was a z71 too and rode much, much softer then this.

I would really like to get this figured out because it, along with a few other

smaller things is preventing me from loving this truck.

 

My new sierra just had this problem, it was bad tires. They replaced all of my tires and not an issue since.

Care to share details. Tire brand, replaced with?? I think it would help those who are experiencing this problem.

Going down the road, especially between 70-80mph had a bad vibration, could feel it in steering wheel. Service advisor sad tires were bad due to road force, gave me all new tires. Tires are the goodyear ls-2s 275/55/20s

If I had these issues I would honestly invest in four good quality new tires and had them balanced by an independent tire shop and I would ask that they remount the same wheel on the balancer for the second time and spin it again to prove that the wheel is properly balanced. To do that, the wheel must be completely removed form the machine , then mounted again. This way if it was balanced improperly due to improper centering, it will show. I would ask if they have Haweka adaptors to clamp the wheel the same way it is mounted on the truck - by lug holes. As wheels get bigger and bigger in diameter, it becomes increasingly more difficult to properly center the wheel on a balancing machine using center cones only without the lug adaptors. It took three tries on my Impala 18" wheels to balance them properly using a Hunter 9700 road force balancer.

 

And now a few notes about road force. What this means is road force VARIATION in pounds. A perfectly round tire will have zero road force variation. However, no tire is perfect, so most tires will be slightly out of round. The road force variation is then the function of out-of-roundness of the tire. The higher the road force variation, the more out of round the tire is. This is why there is upper limit of acceptability on road force variation because if the tire is too out of round, you will always feel vibration, much like from an unbalanced tire, no matter how well the tire is balanced. I had two out of round Continental tires on my Mazda in the past and there was no way to get rid of vibration. So excessive road force must be avoided and the tire replaced. However, low road force number is not a cure for improper balance. Even a perfectly round tire can require proper balancing to be vibration free. So if you had four tires with say 10 lbs road force variation each and some bozo at the dealership balanced them completely wrong, you would still have a bad vibration problem. Keep this in mind. It happened on one of wheels on my Impala. The guy at the dealership balanced three wheels OK, but the last one was balanced the next day by someone else and it was done completely wrong! When checked on another Hunter 9700 machine, it was 1 ounce out! Which means that a 1 ounce (24 gram) weight needed to be added to properly balanced the wheel. The old weights were removed and wheel rebalanced and it was done right this time.

 

The biggest source of error in using a machine such as Hunter 9700 is usually not the machine itself, but the operator. The machine should be properly calibrated to begin with. Typically high volume tire shops do this once a day by using a calibrated weight. The wheel to be balanced must be properly mounted on the machine and this is the source of most mistakes because most operators do not take time to do it properly. Lug adaptors always give more accurate results. Centering cones are usually OK for smaller diameter wheel, but anything over 17" and you may get skewed results. Finally, just because the machine displays all zeros does not mean that the wheel is properly balanced. Ask to have it taken off the machine and remounted and then spun again. I have watched the number all over the place when I asked the technician to do this on one occasion. What was a "perfectly" balanced wheel, not needed 1/2 ounce weight on each side all of a sudden after remounting and respinning.
