I looked but could not find a reference to any lube points on the 05 Super Duty Diesel Dualie.
I won't fool with asking the Dealer. He denied the exausht leak since day one. The Parts Department has never ordered replacement hub cap bolt cover that I asked them to about two months ago. That's the last money they get from me.
Are there any lube points and if so where are they on a 4x2 dualie?
