general problems of the 2004 Lincoln Aviator

I had just gotten onto the highway,at about 40 mph the rear wheels started to skip and jerk also there was a loud cluck from under the front. . . . The mechanic found the transfer case was damaged due to cheap Ford parts. . . . .

I purchased my truck used in December 2011 and it has been nothing but constant problems. First, the door locks would randomly engage/disengage on their own. Or if button pushed nothing at all would happen. While the heater works, it emits a death rattle before blowing air. My ac doesn't work at all and was told that I would need to replace the compressor. The most dangerous and expensive repair has been replacing the front differential mounting and wheel baring. I was told that it was only mounted on one side and was leaking and this was a common problem with this model car. The mechanic was actually able to shake my wheels with his bare hands. The front end stuff actually dropped from under the vehicle as I as driving. Luckily I was able to safely pull over and had to be towed on a flat bed because the front end was so damaged. Repair costs $1400. And I was advised that it would probably happen again! prior to this I also had to replace the wheel bearing and ball joints. Ford does not stand by their product!.

The back hatch panel cracked was fixed , the steering not right some times its hard to steer. Main problem is cylinder coils going bad alot. Now #8 coil went bad and has been replaced 2times, and its still in the shop they cant find out why it keeps coming up #8 still misfiring . . They think its the head now. I understand Lincoln has had so many problems with this that they have allowed a 10yr. Extended warranty on all the coils. Is this right ? I want Lincoln to do something. I am so mad right now . I will never buy another Lincoln. Help me.
