Why is Mitsubish Lancer making metal like squeaking noise ?

[lakey]

my 2005 Lancer makes a terrible metallic like squeaking noise when i bounce the rear end i have replaced the bushes and still not resolved and no one appears to have the answer. hope that someone in this forum can help

the abnormal squeaking noise must be the harmonic damper on crankshaft pulley ( if equipped).

hope this will resolve the problem.
