You can contact you local FORD dealer's service department, give them your VIN, and ask them about TSB's(Technical Service Bulletins) or recalls. The must tell you about recalls, if you get no answer on TSB's from the service dept, contact the dealership parts department they would know about any problems with FORD products if they know what they are doing. The parts department can also look up a replacement balancer, their software should raise a flag if there is a popular problem concerning that particular engine or part. Hope this helps, Good Luck!
