I've found some info that says you take off 3x18mm bolts from the back, then implies you take the hub off to get to the next step.

I've found a replacement bearing hub for $213 (National brand) and $129 (Master Pro, O'Reilly's house brand). Any opinions on that? About $100 difference, though I have heard National is the best brand. I would like to save the cash, but not if Master Pro has a chance of being faulty or failing after a short time.

Do I need any seals, grease or anything else for this job? I see that I need a torque wrench and possibly a puller? A 37mm socket?

Thanks again
