I have noticed the new Ford diesels are very quiet. Was running down the road next to one, barely heard it. Was impressed. I am at 78K on my 2005 RAM 2500 long bed hemi. Everything seems tight so far. Hopefully the front end issues are few and far between. But then I am looking for an excuse to put on a small lift kit, larger tires and front end upgrades to match. :-). A failure up front would help me justify my desires. Darn Michelin LT265/70-17 tires refuse to wear out also. Not helping me realize my dreams.
I pulled the leveling kit on my 2007 and 285/70-17s fit completely fine on the stock configuration, it was running 35x12.5s with the leveling kit when I got it and they'd rub slightly at full lock. Not a huge need to lift unless you're really wanting to.
