Default Left Rear Noise CV joint or wheel bearing?

Hi guys, I'm new to this forum so here goes my first question.
I have a 97 Legacy outback AWD wagon and I am getting a dull grinding noise
that changes with speed. It changes to a buzzing noise at about 60mph
and it is not heard when making a sharp right turn. It will sometimes
make a clunk noise when I put it in drive and the clunk will happen sometimes
when going over a railroad track or a sharp bump. It's definitely coming from the left rear wheel hub but I cant tell if it is a wheel bearing or a CV joint problem. Its not a suspension problem for sure. Also, The wheel is solid when I shake it when its up on a jack so I'm guessing the wheel bearing is OK????? I just dont know....

Definetely wheel bearing. Our bearings are notorious for going out. You should get it replaced soon.

^^^If he has no play while shaking it I'd seriously doubt its a wheel bearing. However the symptoms sound an awfull lot like a bad wheel bearing, I quess the CV is a possibility.

Try pulling on the wheel while all 4 tires are on the ground, sounds counter-intuitive but it could show some play like that. The only reason I'm thinking this is cause with the suspension at full length it may prevent the bearing from showing play.

I'd guess wheel bearing as well. Unless there is obvious damage to the CV joint boot, odds are it's the bearing.

I've had one or two go bad before with no play in the wheel.
