1996 t600 cab vibration

I will look at the balance weight . And check the cab mounts. The vibration tends to stay hum vibration hmmm that may be how will I check for the wheel bearing ? The truck is a 96 and don't think they did wheel bearing

 

Is it right for me to compare a 96 to a 04 peterbilt ?

 

I fixed my cab mounts and still get a pretty good vibration on the floor at idle any ideas ?

 

Nope not yet I have no idea changed can mounts its when I idle it pretty bad my one friend seems to think it maybe coming from the fly wheel or something down in the clutch... I was thinking the engine damper maybe to change that I just did the oh... But I know that is pricey ... Really at a stand still... This vibration really sucks for my leg that I shattered... In a mountain biking accident when I was 18... Makes my ankle hurt I have to wear a ankle brace and a knee brace for me to feel some what okay from the vibration
