What size socket needed for GM front bearing

What size socket is needed to remove the large nut on the end of the half-shaft to remove/change the front wheel bearing on a 1998 Olds Intrigue (3800 engine)? Is it the same socket needed for many/most GM FWD passenger cars? Is it available for purchase seperately, or only as a set? I've been told some parts houses will lend out the socket with the purchase of the bearings, but in this case it may be necessary to leave the thing apart for several days. TIA.
