I've got 180k miles on my explorer and the 4.0L keeps on going! No ticks, knocks, EVERYTHING works including all power windows, locks, cruise, etc. Auto 4x4 kicks in when it needs to, 4 low and high both work outstanding. Might need a new clutch soon, but that's expected. I never liked the explorers much, but I bought this one as a back up vehicle and now it's my daily driver. Despite all of the other negative comments on gas mileage, I get from 18-20 on every fill-up. I think that's good for a big V6. Very happy with my Explorer! The 5 speed manual tranny makes it even more enjoyable! My complimants to Ford on this one.
Good 4x4 design. Handles great in snow, auto works as it should.
