Sounds like your stable is very similar to ours. There are currently five 240's and an 850 floating around here. All but one of the current 240's (and three others recently sold) had some clunking in the front end. Though I've heard much over the years about people replacing ball joints and tie rod ends, I've personally never had an audible clunk (over bumps, expansion joints, driveway entrances) that wasn't fixed by replacing the rear A-arm bushing. I always call this the "pocket bushing" as it goes in the stamped steel pocket that bolts to the unit-body frame rail below the firewall. Any fore/aft movement will cause the mounting stud or the arm itself to bang against the pocket if the bushing is worn. Usually the tube that is bonded to the inside of this bushing comes loose from age/wear causing the problem. Not to say I have never changed ball joints, tie rod ends, stabilizer bushings or front a-arm bushings, but I find that these make themselves known much less frequently and often don't clunk at all. More of a rattle. The low pitched clunk is almost always the pocket bushings. I'm to the point where I can do a single side in twenty minutes so this is an easy project. Contact me for details if you need help!
