While doing some other maintenance, I gave the back wheels a good shake and sure enough, passenger's side feels loose.
Pulled the tire off, the brake rotor has about 1/16" of slop, the rest of the rear assembly isn't moving. Just the rotor.
I'm assuming this is a bad rear hub/bearing assembly?

What is the recommended source for a replacement? Any particular brand to look for, or stay away from?
This is an '84, if that is relevant.

Thanks in advance!

Just stay OEM in my opinion and check Ecklers, JC Whitney, Corvette Recycling.

:iagree: Also try Auto Parts warehouse and Amazon.com.
