I replaced all the ball joints/upper arms and shocks on the front of my 2002 4.6 last year and now I'm getting a knocking noise on the passanger side when I hit bumps. Sounds sloppy but doesnt really feel like it is. Used moog all but except for the lower passanger side and pro comp es9000s for shocks. I had to replace the whole lower a arm on the passanger side due to the shock mounting bracket snapping so i just left the oem joint that came with it in there. Any ideas what may be causing the knocking? I jumped up and down when parked and dont here it.
