I,
Well, people have different ideas of what constitutes an overhaul or rebuild so all I can say is that when I did them every seal, o'ring and gasket associated with the unit got replaced. Your rebuilder should have replaced the axle seals and inner driver housing o'rings. He should also have put thread sealant on the bolts that retain the inner driver housings or those will leak too. You can get the seals and o'rings from site sponsors like eeuroparts.com or thesaabsite.com. The part number for the seals is 87 31 804 and the o'ring is 87 28 156. You should see if the inner driver support bearing is worn out and replace it too while you are in there, part number 87 04 306. Those parts are sometimes listed under "axle and drivetrain" not transmission on their web sites. As long as they are on the bench check your inner drivers for wear where the tripod bearing rollers contact too (although a freshly rebuilt unit should have good inner drivers).
The seals and o'ring associated with the pinion gear housing (inside the unit) can not be replaced without completely disassembling the entire unit and should have been replaced during the rebuild. Disassembly of the pinion housing requires removal and replacement of a large nut that gets torqued to about 200 ft.lbs with a special large socket wrench and Saab gear holding fixture so some people will refrain from doing that which means the pinion shaft seals don't get replaced. Anyway, if your final drive was a half quart low and was spewing oil from the vent tube you have a very strange situation there. I'm kind of stumped other than to suggest that the oil is escaping from some other place like an axle seal, o'ring, bolts or gasket. Maybe clean the area well and then attach a piece of vinyl tubing to the vent pipe and arrange it so that any escaping oil will be collected in a plastic bag or something. That way you'll know for sure whether the oil is really coming from the vent pipe.
