Pinion angle shown in the simplest of terms. Shims can fix this.

Talked again with the service manager. Ring and pinion should be in at the end of the week. I will report back on how it went.

 

After reading some of the most recent comments, I wanted to add what he had learned from GM field engineer. They think that and have also had some tolerance issues with the teeth. Some are measuring zero clearance and some will be at 5,000ths. He said that under load/pressure you could get a vibration because you are going back and forth between clearance and no clearance. Also, the gears warm up while driving and of course when pushing more wind, towing, etc... Could make sense why my truck would vibrate more on a 45 degree crosswind. Again, hope this fixes it. I will report back. He promised me he would let me know what the measurement was of my old gears. Again, build date of 12/13 in Mexico. 5.3l Crew All Terrain.

 

FYI- The field manager said they have replaced 6 sets of ring and pinions in his area. How big that area is; I don't know...

Good luck. My money is still on the use of shims.....

So I have decided to post my ongoing vibration issues to the forum, as it appears I am not alone in this journey.

 

About three weeks ago, I purchased a 2014 Crew Cab, 2WD V6 Silverado with a 6.5ft bed. Recently (as in last week) I noticed a vibration resonating throughout the truck when I reached 30mph, and when maintaining speed, the vibration remained as well. I decided to bring the truck in to Chevrolet, and after a test drive with a service tech, he acknowledged the issue. After leaving the vehicle at the dealership, the issue was diagnosed as a bad drive shaft from the factory, and therefore covered under warranty. I was provided a complimentary loaner vehicle while we waited the four days for the drive shaft to arrive from Michigan (I am in Florida). Yesterday, I received a phone call from the dealership informing me the new drive shaft had been installed, however the issue was not resolved, and in the words of the tech, "it might be a little worse." He then informed me, they were now unsure of the source of the problem, and they were "attempting to figure it out." No progress update today, and no prediction of a timeline for resolution.

 

I have researched the Lemon Law procedures for FL, and I now must wait 7 days before formally notifying the manufacturer of the issue (the vehicle must be "out of service" for 15 days, OR Chevrolet must have made 3 separate attempts to fix the issue).

 

It goes without saying, I am extremely frustrated that this is happening with a brand new vehicle. And additionally the lack of a priority I feel the dealer has placed on resolving it, has not done much to ease my frustration. Hopefully good news comes soon!

 

I will keep you all posted on the progress.

I am also in Florida. Mine is in for the 4th time now and a total of 17 days out of service. I'm waiting for a new drive shaft to come in next week which they are telling me should fix my truck. I've got a CC with the shorter bed. I hope the driveshaft fixes my vibration but after reading your post who knows. I love the truck but hate driving it on the highway. Let us know what your dealer comes up with next.

Good luck guys. I'm in Jersey. My truck is at my dealer for the 16th consecutive day. This is the third time its been in for a total of 35 days and I just bought it in march!

From the "interesting or what" dept. 2015 Silveado double cabs have a new part number for frame vs 2014.

Returned my 2014 Silverado Double Cab LT 4X4 back to the service department with less than 300 miles on because of shaking and vibration. They got rid of most of the problem by road force balancing and replacing two tires. I still get a vibration between 45 and 50 and again on the highway at 70 plus. My question because I don't think I read it any where on the forum, has anyone had a problem with the power steering control module feature they call Smooth Road Shake Compensation? It's controlled by software and sensors which are suppose to help reduce steering wheel vibration. Maybe it could be sensors or even software not doing the job it's suppose to do.

I posted a link to an article that mentioned that equipment a few days ago.

 

I am going to mention it to service department next week.

M1Tanker, Sorry I must have over looked your post. I feel that the software or sensors could be be too sensitive. I get a loose feel when I drive over a rough road that's what got me thinking about this Smooth Road Shake Compensation feature.

I think that only shields the driver from steering wheel vibration, although I could be wrong. Most people seem to feel it in the body of the truck...floor, seats, etc. I'm betting if the culprit where one item, GM would have a fix by now. I think there are many different items working together to cause these trucks to ride terribly. Junk tires, electric steering, new (defective) body mounts, too stiff shocks, frame issues, poor drive shafts, vibrating exhaust...it's like GM has never built a truck before. Aside from No Starts, poor ride quality is the number one characteristic to avoid in a new vehicle and this has GM stumped? Come on GM. If they're not going to care about us...go out of business already.

No worries fella...good to know someone else is thinking about it.

Update.. Picked up the truck yesterday, road force balanced the wheels/tires again. It helped a bit but the shaking in the seats and steering wheel is still there. Decided to throw on my aftermarket 20s and toyo open country at2s on when I got home. This setup was on my old 2012 sierra which rode nice and smooth. Still shakes.

 

So I've pretty much ruled out wheels and tires. They better take a look at the driveline next. This is really starting to make me mad.

After road force balancing the tires on your truck, what does GM think the numbers should be? I've read where the Hunter machines used to balance your tires at some dealers are made just for GM problems they have. Of course the tech has to have the training and time to spend as dealers are always pushing.

They told me they aim for under 24. My dealer replaces anything higher than that with a new tire, although I think they first try to spin the tire on the rim to get a lower value. Right now I have, or had 2 tires that were at 2, one at 12 and one at around 8 I think? It drove better but still has a shimmey.

    • 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...
    • 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.  
    • I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou
    • Is it an optical illusion in the pic or is the truck really squatting that much horribly?
    • 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.
