going over little bumps or uneven roads and you hear knocking, ratlling noise then it’s def. your comression rod. one side was gone on mine but i replaced both sides as that will soon go to. if you need hookup on the parts let me know. Nissan sells it for $303.00 + tax per side. i can get for a bit cheaper (OEM part). shoot me an email at [dtran80@hotmail.com](mailto:dtran80@hotmail.com) if interested. thanks > [@Snakes will eat ANYTHING](https://forums.speedlife.net/t/snakes-will-eat-anything/3298/30): > > 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 ? --- _[View the full topic](https://forums.speedlife.net/t/350z-help/136479)._
