Now that you have it apart use the best synthetic bearing grease you can find. I used Amsoil myself but the brand name isn't what matters. I melted the stock grease with my racing and had to replace my front wheel bearings. The synthetic has lasted and protected my "new" bearings for years now with no signs of fatigue. No blueing from heat and no grease weeping from the cap like before. Do it once and do it right.
