Yes, I highly suggest backing up your data before doing any rebuild. If there is a bad sector on one or more of the drives that hasn't been detected yet, the rebuild will fail and your volume will go offline.
I recently had to deal with similar issue, so I speak from 1st hand experience. It's not all that improbable of a situation. In addition, I would initiate a background initialization and letting it complete before taking a drive out.
