Why Rumble One Side of Album

I've had a few new records that had a very deep (subwoofer) rumble on one side of the album and the other side is quiet.  I'm guessing that this had something to do with a problem with the cutting of the master, but I thought that I would ask.

When you encounter this do you usually return the album, or just assume that if you want the music you need to put up with the rumble?
