Bearing cartridges, turbine wheel and shaft etc. still not available for rebuilding Garrett Ball Bearing turbo's? Returning it to Garrett on the BB program still the only way? I would have thought by now aftermarket companys would offer these parts. Does anyone know of the availability of knockoff replacement parts for these units Chinese or otherwise?

 

Specificly, I am looking to find a replacement GT40R turbine wheel/shaft new or used in good condition.
