Hello frankym,
I have SPF 1593 and at 600 total miles experienced a clunk in the drivetrian and some driveline vibration. The problem turned out to be the left rear inboard CV joint had disintegrated. The CV boot was still intact. With the car jacked up you could rotate the left rear wheel about three inches before the axle stubbed into the differential would begin to rotate. Superformance warrantied the CV joint. I ended up replacing the joint and the differential axle output seal. As it turns out, I found out that Superformance had a supply issue (shortage) and ended up installing used (rebiult) axles. I was told about 100 in number! I did not like this but they did send me new ford parts. If you have not pinpointed the problem I suggest you carefully remove the large CV boot band clamp and roll back the boot and thoroughly inspect the insides of you CV joints.
