if i lived nearer would have come done your car f.o.c for you
im sure someone with a generous heart nearer you will help you out
thats sounds like an easy fix ,so am suprised your family friend has asked that much to do it ,or/and hasnt done it as freebie (but if he runs a business gotta respect that i suppose)

just ask someone on here only sounds a cpl of hours work for someone who knows what there doing !!!

shame to get rid for such small jobs that need doing
and as said front discs usually come with complete hubs on the fronts on them
you may have to get the back one pressed in/out
in which case get it all removed and take to local garage with your new bearing and ask them to press it for ya ..

good luck and if you like the car get it fixed
