I'm thinking about doing a DIY bearing re-pack on my front and rear Deore XT hubs. They are running smoothly, but it's 1) been "enough" miles (yeah, i probably should have done it earlier), and 2) i figure it's time to learn how, and from what i can tell it's not too difficult (i have time, patience, and am willing to supplement my tools if need be).
Can anyone tell me:
1) what size and how many bearings i'll need for the hubs (they're XT HB-M756 front and rear). I briefly Googled, but couldn't find anything specific enough to felt like i knew for certain (fronts is maybe 3/16ths, 20 total; rear is maybe 1/4s, 18 total?).
2)I have figured out that grade 25s are what i want quality-wise; any recommendations for a loose BB supplier, or for preferred BB grease? (For the latter, i've heard rec's for marine BB grease, and white lithium, among others.)
3) is a tool like the "freehub buddy" necessary for a good re-packing, or can it be done reliably to spec without one?
I'm primarily concerned about the front hub, since the rear hub is mostly out of commission; but i'd figure i'd do both if i was already going to do one. I looked up the instructions at Park Tools, and figure i'll just follow those (theirs seems mostly dedicated to the rear, so i presume the front it much less complicated).
Any other tips or points?
