[QUOTE="rich5150, post: 8534902, member: 33227"] Well being as though I had a aftermarket K-member it changes the equation just a bit but I'd suggest this below: #1 Make sure you have rubber spring isolators installed. (top and bottom of spring) Sometimes when turning/moving of the front suspension, the springs can bind up under load and then all of a sudden "give" and make noise. #2, Triple check that when the strut is mounted into CC plate, that turning the wheel all the way from one side, to the other that nothing is binding up inside the strut tower. Have a buddy turn the wheel while you stare up in the strut tower. [COLOR="Sienna"][SIZE="2"][I]-- The problem with this is that the car is stationary... you don't have that "movement" that you do when backing up, or turning thus resulting in something binding up.[/I][/SIZE][/COLOR] I never really did get rid of my sound 100%. Because I have a convertible obviously the rigidity isn't as good as a coupe's would be. I ended up finding a K-member that would accept STOCK a-arms, instead of using aftermarket tubular a-arms. This also included the use of a spring-perch. This took care of 99% of my noise. The only time I hear any popping is if I am on an incline and backing up while turning the steering wheel. See if you can get the noise to replicate every time. Backup a hill, driveway, turn the car in such a way to cause the frame to have to twist enough to create the sound. If the Ford tech says the sound is coming from the tower, it almost HAS to be the CC plate binding up with the spacers/washers on the strut itself (above and below) the CC plate. The Hotchkis parts are usually great parts, so I doubt it would be them, but don't count them out either. Perhaps put the OEM ford CC plates back on, even though your alignment will be WAY off, try to re-create the sound with them on. From this point forward its just a process of elimination of parts. My guess is that because of the twisting of the frame..etc, movement will ALWAYS occur in the front end. Some parts "give" a bit more allowing such movement to occur resulting in no-noise. [/QUOTE]
