So, I took my lifted '10 Fx4 into the service department for the second time regarding creaking leaf springs and a strange "clunking noise" upon acceleration. The first time, the said there was too much slack in the driveshaft and that my tires were off-balance. They refused to fix it in-shop because it was the aftermarket dealers responsibility. By the way, I went through Ford for my aftermarket stuff.
I took it in again yesterday since taking it to the aftermarket shop yielded no solution. I called them about 8 hours after I dropped it off at the dealership and they had no idea what was wrong.
I called back this morning and they still have no idea. All they said was "lifting these trucks really opens up a lot of problems down the road". Well, they have about 4 lifted trucks from the same aftermarket guy on the lot as I am typing this. They never said problems would occur upon ordering my lift in the dealership. Why would they sell cars that are know to cause problems?
As far as I know, I do not hear about too many problems with lift kits if the installation is done correctly. Since I went through Ford's aftermarket partner, I truly hope they will fix this. My only guess, since they don't have one, is that the installation was done incorrectly.
Even then, it might not even be a lift problem and they are using this as a cop out. Who knows.
Sorry for the wall of text.
