[Supras] Supra rear wheel bearings

[Bob]

Has anyone out there had to replace the rear wheel bearings on their Supra?

My 89 has like 68k so it has been sitting...  a lot.... but I am surprised
the bearing would have failed.  I can grab onto the rear tires and as I rock
it back and forth I can hear a clunk.  It isn't like they are falling off
but there is a noticeable amount of movement felt in the tire.  

Additionally I hear a clunk when I pull into the driveway and nothing is
loose in the suspension.

I don't mind tossing $150 at the car I just want to make sure I am not
completely grabbing at straws so could I as someone out there with a smooth
driving Supra to grab onto a tire and see if they have any play in it.

I do suspect this is my problem because the Mr2 next to it doesn't have the
same amount of movement

Thanks

Bob
