Chevy Shake?

[L83_Z71]

Evening everyone, out of the blue I've started experiencing what I think is known as the chevy shake. I've taken my 16 truck to the dealership and of course they say it's normal but it's definitely not. My question is, in the event I have to change the driveshaft what is a good recommendation?

Steel or aluminum, either one would be fine. Both can be built to handle power and high critical speeds.

 

I'd get the stock driveshaft checked first before replacement. A driveline shop could see if it's true and or if it needs to be re-balanced.

I had rpm fluctuations along with vibration's (rumble strip). I found the tsb regarding my issue and sent it to the dealership telling them I want my truck fixed. I already had two dealerships tell me it was normal. The tsb also states, "that no diagnosis beyond customer complaint is required". They flushed the trans with the new trans fluid and it's been great so far. Really smooth, Like a new truck actually.

 

That being said there are other potential causes of the shake. Valve body, torque converter, or the entire trans. But they usually start with the trans flush and go from there. I know online it talks about driveshafts being the issue, but I haven't seen any actually evidence to support that. It came about because owners needed an explanation, and it was taking gm a long while to find the source of the problem. \

 

Don't get me wrong, there was drive shaft issues. But I think gm fixed that for 2016 model year.

prolly transmission, rim/tire, or alignment related.

more so than the driveshaft
