Looks like I am the newest member of the Silverado Shakemup Club. My vibration starts around 50 mph and subsides around 70 mph. It seems that there is little to no vibration if I am coasting or there is no load on the power plant. When going up a hill the vibration gets worse even while maintaining the same speed.

If it were a tire balance problem wouldn't you feel it regardless if there is a load on the engine?

Please advise.

Thanks.

I'm not sure, but if it were me, I'd get the tire balance checked first. Some places will even check it for free.

I have had that problem before. I had my tires balanced and it cured the problem. Just wondering what type of rim and tire setup your running.

I don't have a shakerado...but I fell a terrible shaking under my feet when I drive around 180 kilometres...........Maybe I shouldn't drive that fast, but then again, what was the reason for this worthless post?
