When I go over the right kind of bump, I hear a clunking noise in the front end that sounds sort of like something is loose. It is not a harsh metal on metal banging noise, it is softer and rather unusual sounding. I had the service bulliten done for the fender bolts but it did not help.
I am not complaining about the stiff ride, and would not complain about a "thump" or "thud" sort of noise. I have had many vehicles over the years and never heard a noise like this. I am guessing there is some sort of design defect in many of the 2003/2004 FX35 (and 45?) suspensions. Part of it could be the natural frequency (overall spring/mass effect) of the front suspension (indicating poor engineering), but I am guessing it might just be a bad part or a loose joint. It is more prounounced on the left side, and only happens with the right kind of bump. A small, non-tapered speed bump will do it every time at speeds of 5 to 25 mph. Certain smaller bumps will also cause this noise at higher speeds near 40 mph. I decided to wait a while before complaining about it again, hoping that a solution will be discovered.
I also wonder if the Stillen front end stabilizer bar modification might help, but would prefer not to stiffen the ride significantly.
Thanks for any comments or ideas.
