Guys

I have not responded in a while but hear is what's been going on with my truck .I had my dealers gm rep come out went for a ride me him and sales manger. Rep said truck has a vibration ni doubt.He then had gm engineer come to dealership with a vibration analyzer spent six hours on it did close to sixty miles with two different sets of tires still has vibration .the end result was that the ring and pinion lash was out of spec.(made by American axal corp.) Order me a complete rear end .rotors brake calp.the whole thing plug and play.had rear end installed all low speed vibration was gone but still had some vibration at the higher speeds that we all have but character's of vibration had changed. Went back to dealership told them I want to have my tire road forced balance at a location of my choice on gm dime. At first gm said no that the enginer said it was all set.told then it was not all set they could buy my truck back and resell if it was all good.gm said there not buying it back I told them I would be pursuing the lemon law in my state (MA) and that my lawyer would be contacting them, also told gm rep I was call a relative that works for the today show in NY.two day later the dealership call and said gm will pay to have tire balance and allinement to check the thrust angle with the new rear end installed. Gm engineer told me the spec.is no higher than 18lbs but like them below 14lbs.my road foce readings where rr4lbs lr 9lbs rf 2lbs lr 22lbs that tire is no good tried to do a quick match only got it down to 19lbs .Note left front closes to driver and steering wheel.Went through three more tires before I got a number of 4lbs these are good year 20".so highest road force# is 9lbs. Drove truck and no more vibration low speed high speeds. Brought back to my dealership and took thw boy for a ride they can't believe how much smoother the truxk rides. We then took the same truck as mineoff the lot with 16 miles on it and I watched the head rest shake the back seat the steering wheel shake and vibration though out the whole truck.This past weekend me son had hockey tournament 3and a half hour ride truck was smooth as glass 50 60 70 80 90 miles hour.

So that's my story hpoe it is helpful and good luck to all.

 

Ps some one posted that it was not there problem anymore it was gms they put them in a new truck that he was driving for a couple day to see that it had no vibration before they signed the paper work. Did you trade out or did gm buy it back?

Sounds like another case of good tires fixing an 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

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

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

Modified exhaust per TAC#71-1280001614

Four new Michelins Roadforce balance LF-16 RF-17 LR-15 RR-26

4 dampeners on exhaust. Vibration dampener mat per TAC #71-12880001614.

Installed sound dampening material around steering column and steering shaft to insulate.

Took for ride on asphalt and concrete mix and vibration seems to be gone. Now with it so quiet, it has made the drone at low speeds real loud. I betcha that is a computer fix. It wants to go into overdrive at 40 then dogs that makes the drone. Get rid of that by driving in town in tow haul mode to keep it from going into the high gear. Will keep you posted. These Michelins are smooth as shit but real expensive when I comes time to replace. I trade every two years so I wont be the one buying them.

 

Any chance you've got part numbers for the parts they installed?

(6) 10199232 dampeners

(1) 50032 Hose clamp

(3) 11515174 Barrier

four vibration dampeners on exhaust and 2 vibration dampeners on inside of steering column.

Installed vibration and sound deadener around steering shaft and under hood.

Balanced the drive shaft and replaced front propeller shaft Part # 3020280

Exhaust seems louder so I don't know what they did to do that. Still does have drone but just turn up the radio...

My 2014 Silverado LT, Z71 is having the same vibration issues. I took it back to the dealer the day after I bought it and was told that the transmission just needs to "wear in". I now have 2000 miles on it and the vibration is still there. I will be taking it back again this week. My truck is also making a horrible ticking sound near the engine. Anyone else having that issue?

Mine is in right now for this reason, 2014 Z71, 3.42 rear. I'll let them figure it out but I found in the many posts about this that GM is attempting many things to try to resolve this.

Mine is a gmc all terrain 2014 with 5000k and is having similar issues and the dealer says that it needs to get worse before they can figure it out. I have taken it in twice now. Frustrating!

So took my truck to the dealer yesterday again for the shaking thing. Even took the service manager on a drive. They called today and said "they could not duplicate problem". It's total BS they don't want to do anything. Today I drove a January build 1500 and it does the same shake. I now have no idea what to do I love the truck but can't drive it on the highway without it making my a$$ numb.

Transmission needs to wear in wow that really sounds like BS. You got to get them to put that diagnosis in writing man. haha

The ticking seems to actually be NORMAL I felt the same way you do and made a trip through the dealer lot with my salesman and started about 6 of the 5.3 equipped trucks, they all had a ticking sound, some were a bit louder than others but they all have it. Apparently it is the Direct injection system that they are using on these engines. Dang things are probably programmed to blow up like a ticking time bomb at exactly 100001 miles!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! tick tick tick tick tick tick BOOM

I think my truck came equipped with Square tires they really bounce hard after the truck has not been moved for a few days and the weather is cold. I believe that to also be the source of my whine noise and vibration at speed also. I have not taken it back to the dealer yet just over 4200 miles since Jan 17th

I went to my dealer and tested 4 new trucks and every one of them whines the same... As far as vibration, I think GM has more than 1 issue causing so many complaints. Tires, driveshafts, axles... A new tire for me completely fixed my vibration for now..

I've said this on a few posts but it bears repeating. GM and Goodyear have been in bed together for years. GM could not have put a worse tire on these trucks...the tread is there for maximum fuel economy, and everything else second to that. If anyone wants their truck to ride to it's full potential, the first thing you have to do is pull these junk Goodyears off and out ANYTHING else on. Any after market tire will make a huge change you'll instantly feel. Every new truck I buy had new tires before I hit 12,000 miles...and these ones I doubt will make it through this summer. I wouldn't even bother taking it in to the dealer until you've put a decent set of rubber on the truck. You're just going to get frustrated. I know it sucks to have to sink $800 + into a new truck to get a decent ride, but that's just the way it is. The more miles you put on these crap goodyears, the worse your ride is going to be. For me, Im betting that before I hit 10,000 miles I have 4 new Nittos on there.

In regards to your last line...That's what she said. Take them for a ride and make it do it. My vibration problem is over in the junk tire pile by the tire changer. Goodyear is a 4 section tire and the Michelins are an 8 section tire. More sections smoother ride. GM puts and order in for tires and tells the tire company how much they will pay. Just like everything else, You get what you pay for. There will be a TSB for tire change...

I did take the service manager for a ride. He was like blowing me off. I called GM today and opened a case so we will see. They asked what I wanted, I told them fix the truck to my satisfaction, or buy it back and I'll buy a 2015 2500 HD.

I have some vibration and chatter as well and seems to be the rancho shocks with the LTZ package. they are damn smooth off road but suck on the hyw and I have same rough ride in cold weather, until tires/shocks warm up. wish I had the non z71 shocks that are twin tube VS mono tube for hyw ride.

 

Also have a vibration from maybe the exhaust at higher rpm , just before the shift under heavy throttle.

      New to Me 2010 SLE (Quirks, Issues)

      By davester · Posted

      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.

      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?

      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.
