But softail, you already solved the mystery. It's a drive shaft issue and if everyone just listens to you and has their shaft trued then they won't have anymore vibration. Right ? So why so grumpy lol

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

Post #10240 has links about headlights of another brand of truck. This is a GM forum and the thread is about Shake and Vibrations.

And here I thought we were all friends and were just trying to help one another.... Shame that people can't help people with other brands.

Trust me, I was too until this. Been driving GM since the late 70's. Once this happened I want from a Silverado and a Corvette in my garage to a Tundra and an Aston. I'll never go back.

I just replaced both rear axles with Yukon axles and took it for a test drive on the interstate for about 45 minutes. I set the cruise at 82 mph and that's where it use to shake the worst. I don't want to say the wobble is 100% gone just yet bc it felt like it was there sometimes and I don't know if I'm just super sensitive to it now. It defiantly is smoother at highway speeds after the axle replacement. I will update the issue later after I take an extended trip on the highway.

So... long story short, picoscope showed a vibration in the speed and rpm range i told them, about 35-50 and 3 weights were added to the driveshaft.... seems to have improved the ride, but after driving the same roads in a 2012 Impala 2017 Silverado crew cab and the wife's 15 Sonic, I am apt to think all the roads here in eastern NC have a certain harmonic on vehicles in the 35-50mph range, unless all 4 vehicles had terrible balance and beatup suspension...

 

I would say my vibration has eased to the point that I am not unhappy with my purchase any longer. I would like to change the rough country shocks to bilsteins though. The truck with a 6" lift and 35" Nitto exograpplers rides very very smooth according to all my passengers as well.

 

And the service department was actually very proactive, just took a lot of unnecessary prodding from myself and the wife. Once they started getting the daily 3pm phone call from one or the other, the ball rolled.

Been reading through this forum the last couple days to see what others have tried. I have a 2016 Crew 4WD Z71 that shakes really bad at 65-80MPH. I have been working with my dealer and another dealer in a nearby town and they have not been able to fix the shaking. Both dealers insist that it is normal for full size trucks to have some "vibrations at higher speeds" which is just BS. I have owned/ridden in several full size 4D 4wd trucks that ride butter smooth at all speeds on good roads.

 

After 7 dealer visits and being with out my truck for a total of 40 days I am giving up on GM fixing this or making it right. During this time I have driven 6 other trucks that had at least some shaking with 2 of them being as bad as mine. I will never buy another GM product, period.

 

Both dealers have refused to change anything other than tires/wheels. I am on my third complete set of tires/wheels and a few one offs (15 total different tires) that the dealer swapped out. None of those changes made any difference at all. I currently have 20" KMC XD wheels with 285/60 Toyo Open Country tires.

 

Before giving up I would like to start trying some NON OEM replacement parts and would like any advice on what others have used either to correct this problem or just in general.

 

Going to start with driveshaft but not sure where to get one from as there isn't any place local that makes them.

Torque converter?

axles?

rear end?

Do plan to swap out the shocks with Bilstein 5100 shocks. I did have a rough country level kit added but that had no impact on the shaking. I guess it could be removed with the Ride-Height Adjustable Shocks?

 

I am considering a 6" lift but need to fix the shaking first because in the end I will need to trade this off for something else rather soon.

 

I am willing to do about anything to fix it. I don't have a shop or lots of equipment so will need to find someone local that will do some of the work for me.

 

One last thing, the shaking is extreme when pulling a loaded trailer. ATVs or boat...

I just replaced both rear axles with Yukons. It didn't shake when i went for a test drive after i installed them. I'll give a better update whenever I go for an extended drive on the interstate

New axles? What year?

I had the very same issue as the original OP the dealer told me wheels and replaced all 4 rims that didn't fix it then I replaced all 4 tires that didn't fix it, alignments, among services among services at multiple dealers and no body could figure it out and then my transmission pump finished going out turns out that was the problem the whole time and that's why this shaking only happens when accelerating, I happened to be on expressway so of course the transmission was destroyed in my truck the dealer replaced it with a new one, and I was told by several service guys this seems to be an ongoing problem with these pumps.. so I hope this helps some others because it was a huge headache for me.. let me know if you have any questions it hasn't done it again since the new tranny was installed

It's hard to believe that a billion dollar company with unlimited engineering resources can't (or won't) figure out what their flagship truck's vibration problem is. They either know and don't want to have a recall or publish TSB's for a couple million trucks,or they would rather piss around handling the problems individually hoping that a customer will just tire of it all, or have the occasional buy-back, have the customer get the same issues with his new buy-back.

 

To a large degree the dealer's hands are tied because they just can't spend money on GM's engineering problems without getting reimbursed for their warranty work. For everyone that posts here about the issue there are 10 more out there that that don't.

 

We can send people to the moon, build multi-billion dollar aircraft carriers, supply 20 million dollar golden parachutes to retiring or fired GM execs, and GM can't or won't fix the flagship vehicle's vibration complaints.

      Roll up bed cover experiences

      By StingerZ16 · Posted

      I started with a folding cover by BAK PAC on my 2500. It went bad after close to 5 years. Bent and vinyl coming loose. Contacted BAK and they gave me a very good discount on a Revolver. Had it a number of years. Mostly outdoor storage. Some garage storage. Vinyl started to come loose. Still under warranty so they replaced to cover. Sold the 2500, bought the 1500 and got another revolver for it. Had it a couple years now and no issues. I store it indoors. Got a bit of discount when buying it as well. If you are seeing problems, contact BAK or real truck and let them know. Customer service was pretty good. But I think they changed their warranty.

      Towing In Loose Gravel

      By Chuck FB · Posted

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.

      Towing In Loose Gravel

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.

      Desirable - as in does someone WANT one, aspire to have one. Could reasonably buy any car they want and CHOOSE these instead.    I didn't watch the video, why did they win?

      The use of absolutes like "always" to describe gear selection, and giving free advice at a boat ramp sounds like a recipe for disaster. It's a boat ramp, not a farm, for starters.   IMO gear selection should depend on the obstacle. If low range is working and this is a slower speed, controlled ordeal, I'd keep using that.
