Could very well also be an axle. Easy to visually see if any of the boots are torn. However I have an issue on my '79 were I get a vibration/noise on the highway from the pass. side axle despite the boots being intact. It's worse when there are passengers in back or a trunk full of stuff. I know it's the axle because it got really bad recently, sounded like a flat tire, so I pulled off and the inner can by the differential was smoking!

It is now parked and I have an axle ready to go in...

So just because no boots are torn doesn't mean it can't be an axle, is what I'm getting at. If you check the bearings for play and find them to be OK then you may need to pull the axles at some point along the way in diagnosing it. It's much easier to test for excess play with them out of the car.
