Retorquing the body mounts because it was still there with the new tires and shocks

Wow great to hear! I'll probably go out and check mine this morning or this evening. Have you had it out on the highway yet? I saw you had the 40mph (ish) vibe and the 70+. Thanks for the info!

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

JC, when I brought this up, I did not know which bolts exactly. Still don't, just know the tech said body mounts. Care to provide an example. Thanks.

Cool beans. I will add that the tech/engineer, whatever you want to call him, stated that they would loosen them, drive down some bumpy roads, then re-torque. Basically to get everything to settle.

 

JC Is this what you did?

Well I know I am getting in on the tail end of the forum. I had a 2013 silverado WT and traded it in for the 2015 work truck. Identical options plow package tow package. It is like night and day. The 2013 rode like a Cadillac were the 2015 I have problems keeping it on the road due to such a hard ride and vibration. When I hit a bump the truck is all over the road and forget about taking it on the highway. The last time I did I thought I was going to loose both kidneys due to the violent shacking of the truck.I bought the truck in March and now have 2900 miles on it. I am on my 2nd set of tires and still seems no one has a clue on how or if the problem can be fixed.

The sad part is I work for a GM dealership and can not honestly push there trucks knowing of the problems I am having with mine and still sleep at night.

Welcome to the forum jpcons,

 

Yes it's a very sad deal, GM is selling so many that they have the attitude that until it hits

national headlines they will not focus on the actual issues and keep putting band aids on it.

 

I had a '14 W/T brought it in with a bit over 300 miles GM put over a 1000 miles on it and

had to take it back. four sets of different tires two different sets of rims, Ring & Pinion, Rear

Differental, body mount deal and up until they put the check in my hand it was deemed

' Normal Opperation '

I loosened and retorqued the body mounts one at a time tonight. I probably should have loosened all of them and the retorqued all of them instead of doing them one by one. I'll give this a shot and if nothing I will loosen them and drive around a little and retorque and see if that helps.

This is not something I'm proud of.....more disgusted than anything. After 3 sets of tires and a set of wheels....my truck began having the same issue again ....70 plus speed and vibration. I refused to take it back.....looking at all the owners on this forum and no resolutions......the outcome for a fix seemed bleak and dismal at best. It seem some people are happy with their trucks and that's great ... just not my testimony.

 

I saw owners with 2015 models having the same issues and the service e departments doing the same recourse as what I experienced.....change tires several times......road force balance and pretend there is not an issue. I know Chevy to be a good brand (bought my wife a brand new impala Ltz last year too)....but I refused to give them another shot.

 

After 3 sets of tires a set of wheels and 2 other issues ( resolved ones) and 11k miles.....I got rid of my Silverado and got a Tundra. For 45 grand I expect something reliable and my truck just didn't show that to me.

 

Very disappointing especially since I spent over 2500 dollars in accessories for my truck. Truly liked the vehicle. ...hated the issues! Good luck....I kept every service record for when they do recall the truck...I felt like I was forced to get rid of it since in my opinion....they never could fix it.

Hate to hear about your problems and while the shaking sucks how does that show that the truck was "not reliable". Did it break down on you or something?

Well over a week ago, I had all tires road forced balanced and an alignment performed. Steering wheel and rear shake.

 

Vibration still present, but felt a little better in the front. Took it back and told them, I think front is better but can't tell because of the rear vibration (work order actually states that). They warrantied 2 rear tires.

 

Rear tires on and it helped with the rear, now it just shows how bad the front vibration is. They road forced the fronts so I guess they can look elsewhere for the front vibration (on their dime), or admit that the front tires are out of spec and buy me 2 more tires.

 

Do we have the GM spec or TSB for the road force specs? 15lbs or less?

For p metric tires on a light truck they should be under 25lb of road force as per the defaults built into the GSP9700.

15lbs is correct for the 2014+ trucks. Used to be 24lbs I believe, but GM lowered it with all of the vibe 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.
