NHTSA Complaint #10278647 — 2008 FORD F-350

I HAVE TWO 2008 FORD F-350 SUPERDUTY 4X4 TRUCKS. ONE TRUCK HAS 39000 MILES AND THE OTHER 61000 MILES. AT HIGHWAY SPEEDS, AFTER HITTING UNEVEN ROAD SURFACE OR BUMPS, THEY BEGIN TO SHIMMY AND SHAKE SO BAD THAT I HAVE TO PULL OVER TO GET IT TO QUIT I HAVE HAD THE TRUCKS IN NUMEROUS TIMES TO FIX BUT THE PROBLEM ALWAYS RETURNS. I RECEIVED NOTICE FROM FORD THAT LOW TIRE PRESSURE CAUSES THIS BUT I MAINTAIN CORRECT TIRE PRESSURE IN BOTH OF MY TRUCKS SO I KNOW THIS IS NOT THE PROBLEM. I HAVE BEEN RESEARCHING THIS ONLINE AND THERE IS A COMPANY CALLED WCMOTORSPORTS THAT CLAIMS TO KNOW WHY THESE TRUCKS ARE DOING THIS AND THE SOLUTION. THEIR WEBSITE IS WWW.SUPERDUTYWOBBLE.COM. THEIR PHONE NUMBER IS (508) 668-8638. THEY SEEM VERY KNOWLEDGEABLE ABOUT THIS ISSUE. THE PROBLEM IS THE REPLACEMENT PART TO FIX THIS IS $825. I FEEL THAT THIS SHOULD BE A RECALL ISSUE. AFTER LOOKING ONLINE, MANY PEOPLE HAVE THIS PROBLEM. I HAVE NOT MODIFIED THESE TRUCKS IN ANYWAY AND I FEEL THAT IT IS ONLY A MATTER OF TIME UNTIL THIS CAUSES A FATALITY IF IT HASN'T ALREADY. *TR
