I've got the truvative giga x externall BB and it sounds really rough as it turns but I've only had it 6 months. Can you strip and grease or is it a sealed unit meaning I probably need another?
At the very least you can normally pop the plastic caps off wipe everything clean, smother it in grease and buy yourself another month or two...
6 months out of a Truvativ GXP, you have done well.
Failing a remedy, what compatible BB would you replace it with (thats not mega money?)
Hope
Usually the spacers will come out and you can remove seals and re-grease bearings, usually it's too late to get much more use out of it though.
In answer to title thread:
No, not at the same time...bit of a strange request.
Sorry, very bored at work. IGMC
It is possible to replace the bearings
without any fancy tools.

Just ordered a HT2 BB kit from Enduro in America. It would be easier if the bearings were a standard size (Shimano anyway)!
Thanks for the replies and links, think I'm gonna just buy a new(different brand) one, after googling it and from whats said on here, seems like these BBs are rubbish!
Its seems quite random as to how long they last. i had 2 years out of a gigaxpipe. Foolishly replaced it as a matter of course one day and the replacement lasted less than a month. Really strange.
once it's rough its too late ime; you can stretch it out until payday but not much longer
however if you open them up when new, and regularly (like once a month) they should last a loooong time.

Gone and ordered a hope stainless BB and a conversion kit for the truvativ cranks. Job done!
