Well I could post 869 posts but that won't make me any smarter. People like you are the ones clogging up the thread. The very same ones you complain about. Keep posting at this rate and you'll be a moderator before long!

 

I bet your GMC needed to be detailed 100 yards down the road from the dealership. You were probably an excited boy, first truck and all. We all remember our first time. hahaha.. I bet you're the guy who puts his toolbox in the bed by throwing it over the side!

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

My 2015 GMC 1500 4x4 with only 24k miles has had the dreaded shake since I purchased it. Been to the dealership numerous times, replaced 2 tires at my expense, replaced driveshaft, swapped tires & wheels with a 2017 Denali and I still have the shake. It begins at 70, and oscillates from shaking so bad it will vibrate bad enough to shake the entire truck.... continues for a .3 of a mile and gradually gets better. It almost disappears for .2 of a mile and then it gradually returns to the horrible shake. The dealership is at loss for the repair. If a GM representative is monitoring this, please advise. If anyone has truly had any luck with repairing the dreaded Chevy Shake... please advise. Thanks!

Earlier this month, the dealer replaced my drive shaft, ring gear and pinon. This was after several visits to them complaining about the vibration where they continuously blamed it on my aftermarket tires. Luckily my last visit I was able to talk to a service rep that has a clue, he used to be a mechanic for GM so he knew exactly what was going on and actually tried to fix it.

While the vibration is less noticeable it is still there i am scheduling an appointment today to get it back in to have it looked at again along with my radio reception issues.

Let us know if they have a fix for the radio reception issues. Thanks

You got that right, that guy has done NOTHING here to help matters.

Out of curiosity, i put a gopro underneath my truck in a number of locations. I found that at the front of the driveshaft (transmission side) it bounces and flexes all over the place and looks like its moving through the transmission. I feel like the design as well as the quality of the driveshaft is creating the issues with seeing it actually flex a lot under torque load and appears to not even be round in slow motion. For the people who have dealt successfully with the dealerships, would it be wise to bring video evidence to the table when i talk to them, or just play stupid and let them balance my tires for the 15th time just to get a response?

Here's another victim. 2017 GMC Sierra 2500 Denali Duramax. Truck is shacking since day 1. Brought it to the dealer today after 2 weeks of owning it, they did a "Road Forced Balance" on all 4 wheels, and its still shaking, starting at 50 and around 70 MPH its worst, to the point that the passenger seat is going sideways and I can feel it in the steering wheel and seat. Its not super extreme, but annoying enough that I avoid longer trips on the highway. It is constant at those speeds and gets better at 80+.

 

Any ideas in my case? I'd hate having to read 748 pages with all this troll crap in-between.

I haven't heard too much about the 2500's. This thread is mostly about the half tons. Sorry about your situation though... And unfortunately, welcome to the club.

Oh, I didn't see the 1500 sub-forum, was coming in from a search result in Google. Well that gives me hope that my case might be easier to fix. Now I feel bad for all you 1500 guys.

 

GM really needs to get their quality straightened out. I also own a Vette... total nightmare.

Chevys are known for many years for the sloppy slip yoke. Makes the loud clunk while switching gears or direction. (In and out movement of the shaft) as for side to side and up and down, did you happen to see if it's the huge bushing the transfer case sits on overflexing? ( Or maybe the the transmission also ) mine gets worse in the summer. Wonder if the warmer weather softens the bushings.

I had that slip yoke issue on my 08' and rear end went out twice.

 

You can definitely see the transmission jumping and moving with the driveshaft and was considering maybe using a stiffer energy suspension type mount.

 

I just feel like there is a whole lot going on just by looking at my video like the soft mount, out of balance shaft, heard that the aluminum shaft sidewalls are particularly thin which would explain the flexing as well as it looking out of round just to begin with.

Agree about the historic slip yoke problem; had it with my wife's last of three Suburbans and I had it with a 2008 Silverdo Crewcab. In fact, had two yokes replaced under warranty and numerous cleanings and greasings, all temporary fixes. I finally gave up and just drove it with the condition. The problem gradually diminished as I racked up the miles. Just fyi though, there is DIY fix that supposedly works pretty good. Tap and thread the female piece of the yoke on both sides exactly across from each other (for balance) and install grease fittings in each tap. This enables easy application of grease whenever yoke starts binding. Btw, I never did this, too lazy

Btw, and completely off topic; as usual, lol :) there's another historic problem that I believe some little nefarious engineering elf in the bowels of GM designs into every model year after year. It's the chronic sticking folding mirror problem. I've had this condition on one of my wife's Suburbans, my 2008 and current 2015 Silverados. I've never been able to have the dealer repair any of these as the mischievous little elf back at GM has engineered this condition to be none repeatable while on dealer property. Ok, I'm through, here's your thread back :)

Ok, Kings X, one more off-topic post and I promise to not do it again till next time. My ac condenser went out last week so took it to dealer as my truck is still in warranty. Was informed that the condenser had failed, developed a leak. When I asked how long it would take to repair I was informed by my service rep that he didn't know because the condenser is on "national back order". Fortunately, I was given a loaner so guess I can live with the wait for awhile. But, problem appears to be fairly large and is apparently across the GM spectrum of trucks and SUV's. Anyway, there's a thread up and running in this forum so I won't post about this again on this thread. But, now you know if your ac craps out on you :)

Most guys fixed the clank noise by jamming a half cut tennis ball in the hole. Do it yourself fix.

      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.

      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.
