All over the world thousands of these complete turbocharger assemblies have been replaced at cost of more than $1000 for the sake of a worn out bushing worth a few dollars! I fixed mine (NOT bent, shimmed, filed, sprung or added clip) and here I will show you how I did it.
Here is a link to the repair kit I used:

My CCZB engine uses the IHI RHF5 turbocharger.
I am not sure how similar the K03 turbo is.
