I've never had a problem with front hubs on my racecar, all I did was pop the cap when I got it and scooped out the factory grease and replaced it with better stuff that kills wildlife right left and centre if you dump it (normally means its good
) that's a metal and carbon(graphite) mix grease and never had issues with hubs. Although my right rear is whining now but not surprising dirt got into that one one meeting when the wheel came off....don't ask I don't think I even know.
