Vibration at certain speeds

Ok been to 3 shops international freightliner and a small shop.
Got 12899.00 in it and still have the problem.
I'll check front motor mount
Someone told me today to check the hight.

 

Only dose it when pulling a hill

 

Look for anything connected to the engine that might be rubbing hard on the cab or frame. Exhaust? / mountings?

 

Yeap had exhausted from motor to turbo change too had a Crack.
I'll change front motor mount and air ride hight level and I gave up I'll run it till it brakes down.
I've never had anything like this in 40 years off driving.

 

Ok thanks

 

Did you figure out the vibration on your truck?

 

No more like a rubbing sound fron transmission and motor
