HEY THAT HAPPENED TO ME TOO! unfortunately i dont remember exactly what i got fixed cause i had a mechanic just fix it and charge me (yea i was dumb back then)... it did have something to do with the bushings. whenever i went over a bump or braked real hard it would make the clunk sound as if something snapped. anyhow i took it to a mechanic and instead of buying a new one (whatever it was) he did some welding and it went back to normal.. sorry i didnt really find out what it was exactly, but all i remember is that my mechanic said it was because i had big rims (18's only but i duno) so whenever i made sharp turns it would hit whatever the thing was. anyhow sorry thats all i remember, but i say u fix it real soon cause mines kept on getting worse and worse until i fixed it. good luck!
