A reamer does not leave a perfectly round hole. It will have hills and valleys. So the king pin will fit tight at first and quickly hone the hole removing all the hills. This will leave you with a slightly loose fit that will be stable for a long time.

On the other hand, a Sunnen hone will make both bushings round and inline. The king pins will stay tight for a long time.

Now you know the facts and can decide how you want to spend your money.
