Rear dif problem ?

I just got my 98Z on the road today and I noticed when its cold I get a groaning/squeeking noise from the rear on low speed turns and it feels like its binding slightly .Is this possibly a limited slip noise ? No clanking or banging .Sounds like an old house window sticking .Any idea what it is ?? Maybe change the rear dif fluid and put the GM posi additive in it ?
Thanks ,Ed
