So on the way to work today I started hearing this loud clunk coming from the rear passenger side. It sounds like something is loose and the clunk is louder the bigger the bump. It looks like the strut mount may be cracked in half. Any of you guys had similar problems? Could it be anything else?

 

if its a sedan its a common problem salt and moisture corrode the mounts ,try searching "stratus rear strut mount" several threads might be helpful
