RE: is it normal for a car sub to rattle in free air?

I agree, you did the right thing by exchanging it or sending it back.
I was just curious what amp you will drive the sub with? You know a sealed box will require more power opposed to ported? Also, JBL should have given specs on what size box to use, or, various port designs for frequency response.
