Grinding noise when using Jake brake!

I have 2016 T680 Kenworth with MX13 motor. Replaced the turbo, charge air cooler and made sure all pieces of turbo shrapnel from previous turbo were cleaned out. My driver took truck from Michigan to Texas and back. Upon getting off of the highway, with Jake on he heard a grinding noise coming from the motor area. He claimed hearing same noise before the previous turbo blew. Could this be the turbo blades rubbing on the inner wall of turbo chamber? This is second turbo in 5 weeks. Anyone experience this issue. Is there a none cause? Any help appreciated

 

You want some help? Try posting it in the "Garage" subsection folders instead of here....

 

where are you getting the turbos from?

 

How did the original turbo fail?
