 I bought this suv with 36000 on it.  I have replaced all four wheel bearings at a cost of around $450. a piece. That started at 46000.  The four wheel drive modual went out at 87000, cost 490. It just turned 90000 and guess what?  The transmission went out, cost 3,550.  I have driven Fords for over 35 years and this is the worst luck I have ever had and of course Ford won't help, I ask the dealer about the tranny at a local dealership and he almost laughed. Not sure but was told the parts are made in Mexico!  Go figure!  Oh the heated seats also quit last year.  Guess I don't need a seat warmer anyway, and I forgot the lift gate shocks, I replaced all four of them.
