Hello,
I have a 2002 Sport Trac 4.0 SOHC with 175,000 miles. I just replaced the front and rear timing chains and tensioners after hearing the rattling indicating the cassettes were worn out. It now no longer rattles when starting, but does at differing speeds and rpms when driving. I can take it on the highway for about 20 or so miles at 70 mph and the rattle will disappear temporarily after that at any speed. After sitting a while the rattle will return. It seems to me that the new front tensioner may be defective. Any thoughts or ideas regarding this would be greatly appreciated.
