When the motor torques over and I hit a bump sounds like something rubbing on the firewall but it's a rotational sound like a bearing. Now the nv4500 is great /60k original trans. Makes no noise even under heavy load/lugging it..

But given everything bumper to bumper had been out it could be anything.. I have looked and clearenced all around the motor and trans,

Just looking for something I might have missed..
 
you are going to love this the band clamp on the turbo wasn't the right one, was loose and the downpipe was rattling... sound travels..
 
I learned something in getting the replacement the he351 has a clamp for the turbo to the elbow that cummins will only sell with the elbow, but grand rock has one that was only 14$...
