Explorer Sport Trac

  • 22,000 miles
Harmonic balancer went bad May 2009, just under 19,000 miles on my 2004 St! left my family and I stranded on I-95 in philadelphia. Ford has sold a lot of replacements but won't issue recall or tsb. The serpentine jumped off the balancer pulley and landed on the rubber mount of the balancer then ate through the sensor. Jan 21, 2010: Started up the St, no problem. Drove one block, stopped at stop sign. Made right turn and accelerated, then the St died; 22,000 miles. Just before it lost all power in the engine, I heard what sounded like a turbine quickly decelerating. Now I turn the key, hear the starter clicking, and nothing happens with the engine. Towed to Ford dealership. There was a rattle just before this happened. Ford service dept. Rep called me late yesterday and said it may be attributed to poor installation of harmonic balancer, possibly not torqued correctly; sounded like passing the buck. He needed permission to pull the front of the engine apart to look inside, I gave him a green light to do so. He just called today and said the "key way and sprocket" are bad. He said they come in a kit with a new timing chain; parts and labor after a friendly discount: $925. The truck is already there and apart, so I gave them the go ahead to fix it. Normal price would have been about $1100. Strange, they have a "repair kit" to fix this particular issue, but Ford says there is no problem with the engine! harmonic balancer goes bad, fix it with new and improved one. Then this happens, fix it with new and improved parts from a "repair kit"! Ford says there are no known problems with this engine!

Explorer Sport Trac 6-cyl

  • Automatic transmission
  • 200 miles
: the contact stated while driving 20mph and below, the engine intermittently stalled. This occurred primarily when the vehicle attempted to slow down or stop. The vehicle was taken to the local dealership numerous times for inspection. The dealer was unable to duplicate the problem, therefore no repairs were made.
