Passenger Rear clunking=bad hub? I'm getting a clunking sound from the passenger rear wheel. I noticed there's a lot of play in and out when I push and pull on the wheel. Is this a bad hub or bearing? If so, does anybody know the part number?

Thanks for the responses guys.
VinR1--Not really hearing squealing or grinding. I'd say the wheels move about 1/4 inch in and out when I test them.
1Bad--The main time I notice it is when I'm slowing down to stop. It's more of a thump-thump sound that matches the wheel speed.
themeal--Good suggestion. My LCAs should be good. I checked pretty much all of my rear suspension components. I didn't find any issues until I got to the axel/bearings.

There is no rear hub on this car. It's simply a bearing that the axle shaft rides in. And it has nothing what-so-ever to do with in and out play. That's a function of how the c-clip and the end of the axle fit in the differential.
Furthermore if the bearings were that bad, you'd more than likely have a pretty bad leak since that much play would tear up the outer seal.
A thumping would make me think that it's more of a tire thing, maybe a nail or screw in one. Could it be a bearing? It could... but that's not exactly a common symptom of a bad wheel bearing.
Have you tried jacking the car up and seeing what kind of noise, if any, it makes when you turn it? And do you have any fore/aft or up and down (not in and out that's not abnormal on a c-clipped rear) play?

They can and do make noise. Some worse than others. Particularly rod-ended LCA's as even a few thousandths of slop in a rod-end will make a clunk. Also the little tiny difference between the 1/2" ID sleeve most use and the 12mm bolt that GM uses can cause noise issues.

I don't really have any other play in the wheels other than in/out. I had the wheels up yesterday. The only noise I noticed was a clunk in the rear end when I spin the wheels from a stop.
