None broken.
I only have 54,500 miles on the truck. I wanted to do it sooner than later.
I pulled the coils off and labeled them. I blew everything out with compressed air. Then sprayed WD-40 penetrant (not the standard WD-40) in all the plug holes. I let it sit for about 15 minutes then started working the plugs loose. From there I replaced the plugs and then put the coils back on. I pulled all the plugs on one side and blew the holes out again then did the other side. The whole thing took me about 2 hours.
The penetrating spray must have drained into the cylinders because when I fired it up it smoked like crazy. I should have warned my wife.
I took it for a test drive and its running great.
I don't know if doing it earlier than recommended helped but I'm happy with the results.
