My concern is that every thread I read, the owners seem to have continued problems after the chain service. Has anyone actually had success changing this thing out?
My truck is an '11 with 155k km
Do you ever get the startup grinding noise?
If you read through these threads you'll find several stories of these timing chains out right breaking on higher KM vehicles such as yours.
If that happens you'll be looking at a new motor for sure. Ford will be happy to replace your chain outside warranty (customer pay).
