I busted a front hub bearing somehow last week and had to replace the hub assembly... I would highly recommend doing this yourself and NOT paying someone... Just throwing it out there for whoever might wonder if they can do it themselves, YOU CAN... it's seriously like 4 bolts (15mm), plus your axle bolt (36mm)... I think the hub cost about $130 with my discount plus misc. sockets (cheap ones which i seem to break often)... If i would have had all my parts already, it would have taken no more than and hour and a half start to finish (generously)...

Pull your tire, pull your rotor and brake caliper, unhook ABS wire, pull axle nut (36mm), pull 4 hub bolts (15mm), hub should slide out with dust guard... grease new parts and axle splines, swap dust guard to new hub... install in reverse to specs... Your ready to ride!

Hope this helps!
