i had a leak from same area, it ended up being a crack in the housing. The axle seals weren't put in place right and leaked oil out, i didn't notice or hear any noises.
I checked the seals, and replaced them it kept leaking, replaced seals again, it kept leaking. went throu about 3 sets of seals and finaly took the trany off.
The Diff bounced around a little and put a hole in the housing. not a full hole but a crack with small peace missing like a pin hole, enough for a small leak.

So yeah. it could be that. It was leaking onto the cross member and was spreading around, hard to see whree its coming from, but you could see it coming out of the bell housing if you paid attention closely.
