If its octalink then are you using the correct crank extractor? If you are using the one for standard square taper (which is a smaller axle) then the tool will just go inside the octalink axle and yes strip the thread. You either need the octalink crank extractor or an insert to place into the larger octalink axle so that the smaller crank extractor has something to push against.

If however you have already ruined the threads in the arms then now a crank extractor is useless anyways. In this case the best way to get them off now is with a car ball joint extractor. (a wedge shape tool with a gap in the middle kinda like a fork) which you bang in up against the bottom bracket and as the wedge works its way down off comes the crank. Sometimes however this can unfortunately damage the B/b.

Go to the website for formula hubs and look it up. I know a lot of formula hubs come with sealed cartridge bearings, if it is loose ball find the bearing size go to the hardware store pick up the same size and get some black grease the thick stuff put some in your hub and pack in the bearings until it is full to both sides, adjust the cones so it is tight but can still spin freely, if it binds there is too many bearings if it won't become tight your are missing some. Enjoy your first hub overall

by any chance was your lbs you were using halfords? call Evans for baring and i would get your lbs to remove your cranks because you will mess them up easily if you do them wrong.
