Re: Jackstands + no wheels = heavy vibration?

This question was never answered, or did I miss it? My take is... who cares! If it performs on the highway under load with no symptoms then I think you are fine. It's a truck... not a pine wood derby car. Get it off the jacks and run it, give it some torque. If it performs, run it. If it vibrates, then chase the problem. Anything else seems to be an exercise!

My two cents, worth the price paid!

Yeah I answered it up there. In a nutshell: It does shake between 50-53 mph. 2 month old tires, been balanced 3 times. Mechanic blames excessive runout, tire shop says he is wrong so wont swap them out for more.

Tried some old tires and got the same feeling at the same rpm but different mph since the tires were smaller. So thinking it was rpm related as opposed to speed, I went into that rpm range while in 2nd gear and it doesn't shake. Thats when I tried without tires and found it shakes even worse without tires.
