Stopped by today at my local dealer for the drive shaft recall and also for the infamous tick sound that ive been aware of for awhile now but haven't had time to follow up on it,due to father being ill,spoke to shop forman which I have agood relationship with is going to replace the thrust washers and the hub assembly,both sides and also provided me with a 2014 Taurus loaner for free,another issue was I informed him I forgot to put the car back to stock and the tune is active,he said in very rare case will a tune or anything else void the warranty,basically ford wants you as a customer and wants you to keep being a ford customer,will keep you posted on the repair.
