check the bearings for ANY loose or Rough feeling While Off of the bike... if they are smooth and not loose, Put Them Back On as you found them... if there is any roughness found, i advise a new headset, complete, since it will have Fresh seals and a new wedge ring too.
Only the TOP bearing uses the centering ring wedge.. the bottom bearing seats onto a chamfer at the fork crown, centering it well.

it may be that all you needed was to slightly adjust the headset preload tension... there are a lot of vids on How to adjust Modern threadless headsets on Youtube.
it's very simple to do, and only takes a matter of a few minutes... watching the vid will take longer!

PS.. is that a Carbon fiber steerer tube?... if so, USE A LOW TORQUE RANGE TORQUE WRENCH to avoid damaging the Carbon fiber, or you'll be buying a new fork.
the proper torque spec. should be on the stem clamp, or listed on the fork... if not, FIND THAT SPEC. ONLINE Before torquing those clamp screws, ok?
