Dear all, i am driving a putra and my car's suspensions have noise after i changed the 'crossmammo' so i let few mechanics to check it. most of them said the noise is from the lowerarm. is it possible?if it is real where can get a brand new original MMC lowerarm and how much is it?if proton original is hw much?anyone use proton before?can it lasting?or someone can recommend a suspension specialist to verify the noise again. please give recommendation.
