Best course... Look up the Proper HeadSET for your bike... then take the bike to a reputable shop and have them order/install the COMPLETE HEADSET, AS A UNIT, not piecemeal...
and tell the owner of the shop that did that "10 balls replaced" work that one of their mechanics either needs trained more, or fired.
that WAS a sealed "cartridge bearing" before it failed and rusted into pieces.
that failed, RUSTY piece of scrap metal should have been replaced, in it's entirety.... and frankly, the ENTIRE headset should have been replaced, at that time.
