Well i went bajain yesterday out in the snow turns out my EGR vaccum line was taking in more cold air than warm i guess..Bent the acuator shaft beacuase of the vaccum leak which caused it to kick in and out of 4x4..Kept smelling burning rubber which turned out to be a boot. also now when i engage 4x4 high ,4x4 low never worked even from the factory. Which all of this are common problems with the small fords but when in engage the 4x4 high it causes the engine to die beacuase my wheel stuck damn auto locking hubs haha but the trucks been on a dirt road its whole life think i could get a new acuator. and i cant seem to find one..know where i can get one?

Thanks
Zac.
