I have a 2007 Fusion AWD with about 115K miles. In 8 years I have not had any issues until now. I had a humming whining noise that ended up with the driveshaft. I still have the problem after being replaced TWICE. The first driveshaft caused a bad vibration mainly at speeds of between 20-30 mpg and under load such as going up hills. They put the original driveshaft back on while we waited the 3-4 weeks for the 2nd replacement. Well here we go again... the new driveshaft AGAIN is vibrating.
Also they have replaced the wheel bearings and cv axles. Please help! thanks
