Okay, that makes good sense.

The only reason I responded to your earlier post was that you seemed to determine that a new headset is needed without really enough info in the OP to determine that. It may well be that the headset is so far gone that even the switch to loose balls won't help it. But then again, that may not be the case at all. When seeking mechanical solutions, I firmly believe in trying the simplest, and if possible the cheapest, things first. Putting one too many balls in a headset cup is not uncommon at all, because headsets are different than other bearing assemblies on a bicycle. They should have n-2 balls (see my explanation in my earlier post), whereas the other assemblies, if loose ball, should have n-1.
