same exact problem, for me what i did to solve it was i put new bearings in and put spacers on each side of the fork. inward sends you the spacers with the fork. I also tightened it allot to
inward parts fit realy tight on everything i couldnt get my headset caps on cuz the fork is a little to wide and scs i had to hammer with a rubber mallet to get on but nothing ever moves or falls off i like it
