If ford will replace it under warranty I would get it replaced since you are planning on staying stock until 100,000. If it will cost you then you might be better just deleting because apparently it is quite expensive to replace from what I have heard.Just turned 70K on mine. No engine or trans problems just a death wobble caused by tires which is a relief. The truck is very tight, no rattles. I hope it stays that way, these Michigan roads are aweful but my 97 and 01 trucks remained tight even with 200,000+ on the odos.
Question, I have sooty tailpipes and i'm pretty sure I have a cracked dpf, should I have ford replace it? It hardley ever regens and I do see a little black smoke when I accelerate hard but that's the only side affect i've noticed. I believe the emmissions warranty is 80k but i'm sure I will end up deleting the dpf at some point in the future. I don't see myself deleting before 100,000 miles though. Should I just leave it alone?
