Question about 2006 Ford Fusion
Happens usually above 70 mph. The knocking is random. It's not very loud. The sound seems to originate from the middle to the rear of the car (starting at seats and back).
If you have a rear wheel drive car check your driveshaft it may be a ujoint may need to be lubricated or replaced...do it soon or you may end up parked on the side of the road.

It is possible that this may be your electronic fuel pump cycling on off to maintain fuel pressure. It may be an indication that the fuel pump is on its way out.... Have you done a trouble shoot with an auto manual specific for your Explorer yet? There should be a process of elimination guide or chart to help isolate the problem.
Hope that helps...=)

SOURCE: upper engine knock
I had the same problem with my 1999 Cobra Convertible, it sounded like valve problem, but ended up being, a wrist pin noise! Replaced the enging and trans, found a new Engine thru Trans, with everything on it for $4300, sold the old one (with the noise) on e-bay, for $4300 plus shipping.
The drivetrain now has about 10k miles on it, no problems! Have someone check for wrist pin noise!
This is a Roush Cobra Convertible, I will sell for $12,500, with a new top! Pictures avalible!

SOURCE: knocking noise from rear of car
There are two common
known problems with the rear suspension. One problem is the rear spring
colliding with the rear lower arm during rebound. This is caused by a
lack of support in the rear lower arm and the upper spring seat. The
solution is to fit a spring isolator sleeve to prevent the metal to
metal knocking. Another common problem is knocking of the top coils of
the springs. A revised rear lower arm spring seat has been fitted since

Sounds to me like a very common problem has occured to your neighbor. If this is a SOHC engine, one of the valve seats in the number 4 cylinder has fallen out. I'm sure it has damaged the head and the piston. Stop trying to run it or you might blow a hole in the cylinder wall or break a rod or both.
