“When driving at highway speed or accelerating the back of the truck will violently vibrate.at time it is almost uncontrollable and becomes very hard to steer. I so I have researched this issue and it seems that there are many complaints about this exact issues with 2014 to 2019 chevy and Gmc trucks. I just had the alignment done and brand new tires put on it the truck 6-22-20. Now the truck shakes even more then it did before.”
