PJ PJ PJ, you should know better after all your work with 5lug swaps and playing with hubs.
No the bearings are not rebuildable, they are a cartridge unit that need to be pressed in or out of hte hub. I did one myself on my old S13 and it took a lot of hammering and i had to use a propane torch to heat up the hub to help release it. :ylsuper OH YEA WD40 and a torch make big flames! He he
Bearing are expensive, its was like 75 for mine IIRC, but i saved money doing the work myself. Just remove the lock ring and start pounding. You can use the old bearing to help press in the new one.
