To the case of this vibration I would like to describe my vibration issue and how it is bieng resolved. First the car is a regular cab 1500 sierra The vibration starts at 120+ KM/h When I set the car on cruise I feel body vibration, where i can see and feel the dash, and seats shaking plus anything in the centre console. Took it to the dealer a couple of days back. Today I got a full report on what has been done to my truck. They started off checking engine mounts, gear mounts, front rear drive shfts, all shocks, front arms, They checked if their was any misfiring, however non of this was on my truck. They decided to make sure my wheels were properly balanced. After the check it turned out that two tires needed to get changed due to many flat spots. They threw these two tires to the back and keeping the two properly balanced tires upfront till the new tires arrive which could take 15 days. I could tell you that with the road force balancer and the best they could do to balance the set of wheels, 90% of the vibration is gone. I drove around 60 KM today at the speed of 135 KM/h and could really feel the difference. Therefore goodyear eagle tires are just not of that high quality, my friend is using them on a ford edge and is having the same issue, his car used to drive smooth till ge changed them with these set of tires. Moreover the vibration at idling is said to be because the engine is running at both v4 and v8 and cant keep its mind at one. This is AFM as the mechanic told. So I gave a call to one of my friends who tuned his car to only run V8. And the idling vibration is well decreased. Hope this helps and just take it easy reduce your tension and just hope its something silly.
