Check to see if the headset is tight enough, or not overly tight. Check all the bolts are properly tensioned and greased before learning two years from now they weren't greased and now they're seized.

Go through all the spokes and check to make sure the nipples are properly tightened.
Check to make sure that the cog and lockring are properly secured on the hub.
