Installing a new axle shaft, let me know if it improves. I spoke to one of my friends which I'll be taking it in for other service, he's a GM tech I use to work with before I stop turning wrenches. He has had two jobs/ complaint with the vibration issues as well, from the dealer point of view, it's normal but I know and we all know and he knows it's not normal but no solid fix. He even test drove a loaner truck that did the same thing as the customers complaint vehicle. He ordered a new driveshaft under warranty and the new driveshaft did not resolved the issue. Also like I stated above I test drove my little cousins new truck with 200 miles and hers vibrates at well under hard acc. I haven't taken mines in as a complaint yet but also I don't want techs throwing parts at my truck with no luck.

Correct.

 

It's hard to tell if the studs are running true, we are going to put an axle in one of them and see if that does it.

 

Do you have access to a truck that doesn't vibrate ?

I've had a vibration with mine since I bought it with 8 miles on it, has about 6,000 on it now. Road force balanced tires 2 times, didn't really help. WELL! One of our techs found this today, and we checked another one with a vibration, and sure enough, same thing. Something with the left rear axle/face on the axle is out of round. I put a magnetic screw driver on the e-brake shoe as a reference. Watch the gap between the axle face and the screwdriver.

 

 

That is an awesome find there! Good luck fixing yours!

Any updates on this?

Back from the dealer for the 4th time. Replaced all wheels and tires from another Silverado on the lot. Same Wrangler SR-A's and 18 inch wheels. Vibration from 65-80 is gone. Seems to be pretty smooth, if I do feel anything at over 70 it may just be irregularities in the road. Now for the bad news. Instead of vibration that I can feel in the steering wheel, seats and center console it is now isolated to the steering wheel only. It feels as if I have extremely aggressive tires or I'm driving on a gravel road. I'm really tired of going to the dealership which is 40 minutes away only to have the same answers of wheels and tires. I'm thinking of taking it to a driveshaft specialist and check to see if the driveshafts are running true. Also while going down the road I have put it in neutral and nothing changes. Does not appear to be affected by AFM or V8 mode...

Brother sad three more came in today with the shakes. One had already gotten tires and they were hucking wheels and tires on the other two. They keep coming because they keep selling them. Owner is driving a demo with the shake but will not fix it until it is sold.

Noticed today while trying to isolate my vibrations, that if you grab the wheel from the back while looking at the wheel and pull towards you it moves slightly. Almost like if you were checking tie rods on the front wheel. It didn't move like a bad TRE would side-side but it does move towards you and i could see how this could be compounded at highway speeds.

 

I'm not sure if this is normal or not, or if anyone else has checked this.

It's normal, inside of the differential, their is a C clip that holds the axle in place so it won't slide out/ you would take the diff cover off then remove the C clip to remove the axle out. A little play when you pull in and out is normal.

Balance and rotate does help, it helped mines. One of my wheels requested extra weights which I didn't like. That wheel or tire are really out of balance. Wish their was a solid fix/ you would think with all these issues, they would have figure out the issue by now for these 2014-2016 models. I wonder if the new 2017 are going to have these issues as well Edited by Amuro

my truck has a vibration at 70kph and a pulsating vibration at 90 to 100kph and then again at 120kph. i put my polaris 700 in the back of truck and the vibration at 70 was still there but at 90 to 100 it was gone. i have had 3 sets of tires and 2 sets of rims on the truck that never changed anything but the weight of the 4 wheeler does

agreed, the colder the better with mine...

I kinda hate this time of year. Too hot for snow tires and to cool for the all season 22s it would seem. At least the vib is intermittent.

Im finding lately just driving the crap out it seems to fix a lot of issues... I've discovered that when my truck vibrates due to being in too high a gear at too low a speed is fixed easily by pushing the accelerator to the floor. The tuner taught me how to drive this truck. Hard.

When it's cold outside the 1st few miles on the highway are fairly smooth. Get more of the vibes after driving for a bit... fk'n weird.

Okay, truck has been at shop 15 days, to replace vinyl that is peeling on both bumpers and emblems, replace a bad shock and investigate the vibration. Get there and neither of the emblems is fixed, there was my first sign. Tires have been rotated and balanced (so I'm told). Barely make it to 40mph and whole truck drives like it's 100yrs old. Used to be only at about 45mph, now it is any speed above 35. Took mechanic for ride. Kid says "well sir, you may have gotten flat spots on the tires"...???

Told him I wasnt buying that answer. Took it back to shop and told service advisor, now they are going to road force balance the tires again Monday.

 

Just like you guys said, they keep blaming the tires... I will be contacting my local GM rep Monday and we are going to have a nice long chat.

 

$50k vibrator my ass.

Good luck with your chat, you won't get anywhere, no matter how much of a fuss you put out and no matter how many treats of suing or BBB or whatever. :( Essentially.. you're screwed.

    • Have considered installing a DC to DC charger in your camper to replace your isolator?  
    • Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.  
    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.      
    • Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
    • I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
