Sierradude · September 1, 2018

Anybody experience the dreaded Chevy shake between 70 and 80mph yet? Has this problem been corrected with the new trucks?

Considering it wasn't all that common on the 14-18's, you might have to wait a lot longer to have enough 2019 trucks for a decent sample size.

Common issue on K2.

Ask Cmillerjr if he has it on his '19 Trail Boss.

GM is beginning to manufacture their own version of the 12-bolt in Michigan. The lack of quality control at AAM was a big contributor to the vibration some had. GM also totally redesigned the frame, increasing rigidity targeting a higher natural resonance. Perhaps that will make it less sensitive to wheel and tire balance.

Tightening my leaf spring nuts made my very mild shimmy between 70 and 80 go away.

It was there, but nothing like some have reported here.

I have not noticed any type of shake. I was on the PA turnpike last night holding at 75 for about 40 miles and it was a smooth ride.

Good news!

Mine is good too. Three hours home from dealer. No shakes form 60-85

No shake on mine. 150 miles at 75 - 80.

!!UPDATE!! Just over 1100 miles, still no shake. Rides just as smooth as day 1.

I don't know why you haven't received your thumbs up emoji yet but you should be getting one! After 1100 miles, have you noticed an improvement in fuel economy? I don't mean actual numbers but just general impressions. I remember this was very noticeable when moving up from my previous two generations of GM's.
