Thanks to everyone for their response. When the truck was new the salesman was asked about the tough shifting to engage the 4WD. He said it would "loosen" up with a little wear. NOT. Anyway the system does work and I guess I'll just have to live with it. I do engage it a few times over the summer just to make sure it works, but I'll make sure to really spray it good with WD40 and to also check the linkage. Again, thank you. New Ford SuperDuty diesel with electronic shift on the fly looks SWEET, now to convince the boss. [img]/forums/images/icons/grin.gif[/img] [img]/forums/images/icons/grin.gif[/img]
