Sounds like a CV joint. When a boot gets ripped, the grease flings out, and the balls go dry (I hate that). It will make the clickity-clack sound you describe. Look for goo on the inside of the front wheels, and/or a small rip in the boot. It only takes a minor cut, and centrifugal force will empty it. 32K miles is about average...especially if you've been wheelin it. Piece o cake to fix...45 minutes a side.
