Check for Free Rotation - Off Vehicle

WARNING: This page is about a different car, the 2010 Ford Pickup, 2010 Ford F550 Super Duty, 2010 Ford F450 Super Duty, and 2010 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Turbine and compressor wheels must spin freely when turned by hand. No housing contact is permitted.

Press and rotate the turbocharger shaft, then repeat from the opposite side. If either the compressor wheel or the turbine wheel contacts the housing, the bearings are bad and a new turbocharger must be installed.
