Well a little update on mine. ?After they put the new driveshaft on it I've had no issues at all! ?Pretty exciting so far. ?I've drove it now a little over 500 miles and it's smooth as glass at any speed. ?The majority of it has been interstate miles, going back and forth from downtown due to my wife's surgery (sure in the hell didn't need this vibration issue on top of everything else going on)! ?Speeds have been all the way up to 85 and NOTHING. ?For the first time in 4 months and 6 trips to the dealership, I actually enjoy driving my truck. ?

?

Don't get me wrong, I'm nervous as I hear several of you talking it was a few thousand miles before your issues started and I'll stay on top of it. ?I really do hope GM figures out this issue and I hope even more all of you get your issues fixed! ?Sucks all of us lose thousands of dollars combined against a billion dollar company who could honestly give two sh%^'s less. ?Luckily I had an awesome dealership that was always willing to try and figure out the issue. ?

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

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

I talked to a tire guy who services my companys fleet about road force balancing. He had one for a while and got rid of it because he said a normal tire balancer that is in good working order will balance a tire just as good in his opinion. We actually used to have balance our own tires at a job I had many years ago and we used a bubble balancer, very old school but worked every time.

I might tend to disagree. There are 2 things everyone should keep in mind:

 

First, it's not "Road Force Balancing". It's measuring the Road Force Variation, and then attempting to correct it. If the RFV is high, there are limited things to reduce it. What Hunter calls "Force Matching" can help, but because of the nature of Force Matching, may not is some cases. Basically, all the tire shop guy can do is index the tire and wheel to cancel out each other excess RFV. But, if the wheel is perfectly round and has no runout, then a tire exhibiting high RFV cannot be compensated. Remember, the RFV is generated by variation in the tire rubber stiffness and/or runout/out-of-round of the tire or wheel. Not weight imbalance. That is completely different force generator. The tire manufacturers will grind the tread slightly to reduce a "hard spot" on the tire, but this is rarely done in the tire shops and GM prohibit is it.GM says if the tires can't be Force Matched adequately, get a new tire.

 

Second, traditional tire balancing is simple a weight balancing correction. So, a tire with excessive RFV can be weight balanced and still shake the vehicle like crazy when it rolls on the road. Now, I know we never did RFV and never had problems. I myself have done many bubble balance tire installs. So what's different? Why is it such a big deal?

 

Many reasons. Cars are much stiffer now, so much more of the road vibration, and tire generated vibration, is transmitted up to the driver. Plain and simple.

 

Tire compounds are much different that 30 years ago. Even over the last 10 years, tire rubber is made completely different. Remember when 30,000 miles was a good tire? Now we have tires last 3 tim s that long. How? Totally different rubber compounds.

 

Remember when cars had 13" and 14" wheels? And pickups had the big 15"! Now, we start at 18". The 22"s on my Yukon weigh twice what a 14" would in the old days. And, that mass I out a much larger diameter, which generates significantly more centrifugal force. In fact, the force goes up with the square of the radius!

 

Add it all together and the tires and wheels need to be much better that 30 years ago.

 

And remember, the tire manufacturers have been checking their tires on Uniformity machines for years, unbeknownst to us. So, it's been done for a long time. It's nothing new. The only thing relatively new if the Hunter GSP 9700 which brought the technology to the aftermarket level and put it in the tire shops.

 

At the end of the day, a decent tire that has been uniformity checked by the tire manufacturer mounted on a decent wheel, weight balanced only, and put on a vehicle that is not SUPER sensitive, will work fine. But that doesn't mean RFV is "useless" as some tire guys would have you believe. They just don't understand it enough to be able to apply it properly, and make is useful. It's a bit high tech, and the tire shop industry has always been on the low tech side!

 

And there is one last thing to consider. Most tire shops will denounce the value of RFV for reasons of cost and practicality. First, the machine is more expensive than others that do an "adequate" job. Second, any idea how long it takes to do the full RFV/Force Matching per the Hunter manual? Several hours. Most tires shops aren't making much profit if it takes that long. And the know most customers won't pay the extra because the whole concept will be way over most customers heads. And most customers will say" what do I need that for? Never had to do that before". Easier for the tire shops to get you in and out quickly, get your money, and carry on with life. And last, I order to actually correct for a large amount of RFV, the only solution is a different tire. How many tire shops carry a massive inventory of each and every tire make, model and size? None. All the shops I've every dealt with have a small amount of inventory and usually,,they have to get a set "from the warehouse" across down. So imagine the tire shop,is going to do a proper, full RFV install of tires for you. You book the appointment and they bring in a set of tires. You show up and wait patiently for 2 hours while the guy attempts to force match out the high RFV on one or two of the tires. Finally, he says "well, I can't get it in spec. I need to order tow more tires. Can you bring it back tomorrow, or leave it here till I get it? May take a coule more days." Most customers would freak out!

 

Sor practically, it's almost impossible to make use of the technology. And most tire shops, even if they do understand it, will opt out. And it's easier to simply adopt that opinion that "it doesn't do anything" then fully understand it explain it.

 

IMHO!!

I appreciate GM Customer Care commenting on here, I have been treated very well by them so far with my issues.

 

I would like to say while my truck is still in for the vibration issue my dealership has done an amazing job at keeping me a happy customer.

 

Wesley Chapel Chevrolet has gone well above and beyond attempting to rectify my vibration, and if anyone is in the Tampa Bay area I highly recommend them because of their level of Customer Service.

I have the same issue, my dealer has been trying to figure out with no luck. It was in the dealer last Tuesday and is going back cause its still not fixed. Has a vibration/ rumbling sound?in floor board?under hard acceleration over 78mph, it wont do it until it hits 78 and then continues up from there unless I slightly let up on gas peddle.

Mine is worse than the Jeep Wrangler that I had before it.... which was a small part of the reason i got rid of the jeep in the first place.

?

sometimes it feels like unbalanced/out of round tires, other times it feels like I'm on a pogo stick, etc. ... haven't taken it to the dealer yet, this thread already has me

jaded about the kind of service to expect so I've been resisting taking it in....

Hello littlecricket,

Nice to see the flurry of posts. Hope you will reaching out to each and every person on this thread who is having unresolved problems. That said, why the sudden activity? Is there any chance you can shed some light with us? And how about the SUV thread with the similar issues?

I have had my 2015 Silverado Crew Cab LT for a month and it has this console shaking issue. Taking to the dealership in the morning for that and a seatbelt problem. I'm not able to read the entire 515 page thread from 2013 until now. Has anyone been able to remedy this issue? I've seen some people talking about this buy back thing or tires/drive shafts out of alignment. I really love my truck and I don't want to give it up.?

?

It seems to shake between 70-75 mph, but not all of the time. Sometimes it's more shaky than others. I've also been on smooth asphalt back roads and not felt it at all. Could it be something to do with rough concrete highways send the tires or something out of whack? I had a 90-something GMC a while back and the steering shook with the cab. Found out it was bad back tires.

So an update on my 2015 Silverado. Since filing for the vehicle defect notice the truck was dropped off at the dealership. During its 10 day sleepover at the dealership they were able to confirm the vibration on the dealerships picoscope as well as the GM engineers picoscope. Like every other time they went back to the tires being by issue. They ended up finding the actual rims were out of balance per GM specs. I believe they said the rims alone took around 7 ounces to balance and weren't supposed to be over 4. Just FYI I have the 22" wheels. They ordered new ones which came scratched from the factory and then ordered another set. They also attempted to balance my original set which the dealer had because they had scratched during the first few visits and had already replaced them. Those wheels were also to far out of specs. They finally ended up getting a good set of wheels finally within GM specs. Next it was on to the tires!!!! Without getting my paper work out I think they ended up using 2-3 sets of tires to get 4 good tires that would pass the GM specs. I also have be Bridgestone duelers A/T tires. During all the balance process the dealer even had the hunter reps being out an actual large vehicle which had the latest and greatest hunter balancerachone on it and tbey used it as well as their in house balanced to verify balancing accuracy. So to end the long story they actually called me on the 10th day at 5pm and said the truck was finished. In Florida all they have is 10 days to complete the repairs. Kind of funny they called and finished on the last hour they had. The truck does ride better but it's been a few weeks and there is still a vibration and the intermittent vibration still comes and goes while at highways speeds. GM customer care called and I told them it still wasn't completed. They said in their eyes the truck was completed and offered me half a months truck payment. What a complete waste of my time. No one from GM even rode in my truck upon completion so how can they say it fixed? It's actually an insult to me that I bought a 50k truck and they think I'm worried about 225$ really GM?? Guess it's off the the BBB to file a class against GM. I have been patient and kept my cool with GM during the entire process but it's a joke how they are treating this issue. I have all documentation and videos and ready to take them the the BBB and arbitration if necessary! Good luck everyone!

Well I hope some of these guys your are asking to PM you get back to us on this thread telling us what you have done for them. I have the vibration problem in my 2015 Sierra and have yet to have it back to my dealer for I know there is no fix for this yet. I do not need 4 sets of tires or new rims just to have the same problem. As far as I am concerned GM should find out what is wrong or just go back to putting 2013 parts back on these new trucks. I had NO PROBLEMS with my 2013 Sierra. This is not right and someone has to make it right. We bailed out GM with our tax money and now you are making BILLIONS and we are stuck with $40 to $60 thousand dollar trucks that ride like a 1972 Jeep CJ5.

I'm wondering if my efforts have had anything to do with this. I received a "thank you" card from GM marketing. It was signed by a GM executive. I reached out to that individual via linked in and shared our concerns via a linkedin message. In my original message, I included a link to my website to help them see the severity of the issues in one place. Another individual reached out to me via linkedin to setup a call to discuss. I obliged as I would love to see this resolved for all of those who had issues.

 

Those that have accused me of not so nice things, sorry that you feel that way. Nothing would make me happier than seeing all of those that are frustrated to have an ear that is willing to listen and help them get the truck that they want. I'm fortunate to hvae been able to buy my way out of a vibrating truck, that isn't the same for everyone. Hopefully this effort from GM is a true effort in standing behind their product. Maybe we never get to 1,000,000 views :)

Posted a video of shake before. Had tires balanced less than 1000 miles ago. Truck vibration seems improved but still there. I think it was mentioned previously about the temperature. It had previously been rather mild temp wise and the truck was shaking more. Now that it's cold the vibration is less. Balance was done about a month ago. I think it's going in for its second visit soon.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      New to Me 2010 SLE (Quirks, Issues)

      By fm2176 · Posted

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      It's Been a Long Time...

      By fm2176 · Posted

      My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.
