What is this freakin' sound???

Whenever i go over a speedbump or dip in the road I hear this creaking/crunching kind of sound.....i asked around and was told, "It's your struts!", so I replaced them(actually a friend of mine did and nearly took off his head when he forgot to use a spring compressor on one and it went off into his face).....so now i'm stuck with the same ole sound and clueless for answers....i'm sure somebody else has had this problem??? oh yeah, its a '96 accord ex teq
