SGT,
+1 with RJ......... Front Wheels=Seals and Bearings
Front Stem/Head=Seal Caps and Bearings
..............and a whole bunch of tools!
If you have grinding or any abruptness while turning the steering head, you may want to replace the races as well!
It's a good idea to consult the manual in either case as the front wheel has a special procedure for aligning tubes when re-installing and final torque.
Cheers.
