I still say BS, there is no procedure to repair the turbo in the FSM. See excerpt from the FSM:
------------------------------------------------------------------------------------------------------------------------------------------
DESCRIPTION
CAUTION: The turbocharger is a performance part and must not be tampered with. The wastegate bracket is an integral part of the turbocharger. Tampering with the wastegate components can reduce durability by increasing cylinder pressure and thermal loading due to incorrect inlet and exhaust manifold pressure. Poor fuel economy and failure to meet regulatory emissions laws may result. Increasing the turbocharger boost WILL NOT increase engine power.
The turbocharger is an exhaust-driven supercharger which increases the pressure and density of the air entering the engine through the charge air cooler. With the increase of air entering the engine, more fuel can be injected into the cylinders, which creates more power during combustion.
The turbocharger assembly consists of four (5) major component systems
Turbine section
Compressor section
Bearing housing
Variable veins
Actuator

What is the part number on the invoice? Can you look up the part number here?
http://www.moparonlineparts.com/I know even with heavy trucks, they are not repairing these in house, they either get new or reman.
