hey guys i need some help, i’ve got a 03 350z i noticed in the front when im driving over bumps or step on my brakes i hear a knocking sound. i had a look under the car and noticed that my lower control arm bushing is shredded up on both left and right side. anyone had this problem ? can i just change the bushing or do i have to change the whole arm ?

Do you mean the rubber bushings at the pivot are torn up? or the rubber boot around the ball joint is torn up?
To me this sounds very much like an endlink issue. Is your car lowered w/ aftermarket suspension? if so what have you done?

the car is not lowered it’s all stock. took it to a shop this morning and they said it’s not the bushing but they think it may me the lower control arm ball joints. it knocks pretty loud when i hit bump and when im travelling a low speeds and hit the brake
