Pulsing vibration felt in steering wheel

[RB_Racing]

I had this issue early summer on my 2016 SLT with 20 inch wheels. Truck only has 45k kms on it and original tires.

Initially the vibration happened when I was pulling a small enclosed trailer back from the race track. It didn't do it on the way there!

 

Vibration was at 100 to 110 kph (60-65mph) and was not constant more like in pulses. Took my trailer off the next day still there.

Since i didnt rotate my tires or maybe once! I rotated my tires checked pressures and torqued my lug nuts. The vibration seemed to go away all summer and I did 5 family trips with it.

 

Drove it yesterday and its back at the same speeds. Its getting colder here so I havent bumped up my tire pressures so i will try that.

Vibration is felt from the steering wheel and if I put my hand on the consol I dont feel anything. Planning on new tires for next spring.

 

Anyone have something similar?

I would start with your tire pressure and adjust that accordingly. If the vibration is still there after that, I would look into seeing if the tires need rebalanced.

You my friend might have the notorious '"Chevy Shake".  I had a 2016 SLT Sierra and it got the shake at 3k miles and the Dealership had it for 6 months to try and correct it.  They put a PECO-Sensor on the steering wheel to test for it. They tried new rims/tires. They checked the drive shaft. They brought up a technician from Texas to try and fix it. He did a better job than anyone around but I still felt it on my hand when I was driving. It was a subtle vibration that "basically" put my hand to sleep...went numb.  Here's what I found out about it because it drove me bonkers paying on a truck that wasn't in my garage. GM ended up buying it back and I got a FULLY loaded SLT with 2 headrest DVDS for my kiddos. It was a 5.3L and 8 speed combo and I didn't have a single issue with that truck  

 

Rims and tires cured some trucks

Drive shafts were a huge problem...many were unbalanced from factory, fixed many trucks

Putting HD cab bushings on the 1500 trucks helped also, but that was very expensive fix because you had to lift the truck cab completely off the frame.

 

Hopefully its just unbalanced tires or a messed up rim. Good luck.

I tried raising tire pressure and it was still there.  Drove it today 40 minutes on the highway did it all the way to my destination came home on different roads brand new asphalt and it wasnt there?

 

Ill try and re-balace the front tires next. Its so weird as some times it does it some times it does not, and its not a constant vibration more of one second vibrates then stops for a second?

Mine did it at about 70mph. Flushing and changing the tranny fluid made huge difference on mine. Truck only has 35k on it.

my 2014 was the same 55 to 60 mph and the pulsing vibration would start, and the same as yours on smoother roads was not as bad. GM tried many thing and then gave up. i asked them to check the driveshaft and they said they did and it was fine. they lied, i put a new driveshaft in and problem was gone
