Is this a defect with them. I have heard and know so many ford owners having to change there cylinder heads.
Can anybody help with this situation?
Manufacturing defect, known defect in the WLT heads since 2005 onwards.
Most people discover the crack too late and end up having to spend up to $6000-$7000 on a new head and/or head and block.
Problem is due to poor maintenance or lack of proper maintenance of the cooling system - need to keep an eye on critical components like the thermostat, keep the radiator flushed/clean regularly, use proper coolant, check clutch fan & fan fluid regularly.
Again, most ppl think the ranger/b2500 could take real jammin', and neglect to maintian the truck properly (common mistake among diesel owners) and then want to cry when the inevitable happens.
Best thing to do is immediately go through your entire cooling system, and check your fan/thermostat right away. Then pressure test your head to make sure your ranger hasn't become a crack-head.

This has also affected the speedometer, not showing the correct speed if at all.
Any help would be appreciated.
Most common cause of 4wd sticking is due to vaccuum lines being either stuck or popped off the actuator. Go under the truck and check near the center diff to see if any lines/hoses are loose.
I'd advise that you don't run the truck while in 4wd - running the diffs on hard, high-traction surfaces will stress out the diffs and cause driveline binding - basically your differentials are designed to slip a little bit when driving on a loose surface in 4wd. If there's too much traction, the differentials will start to wind up and bind, and this can even cause the gears to break and shatter!!
So take it easy, if you can't drive the vehicle in 2wd, then best thing to do is stop and tow the truck home on a flatbed....... it's either that or have to go buy a new set of gears and possibly axles too (might strip out the splines!)
