This is the problem that i had with my jeep, not being a mechanic i tried all sorts e.g blow torching the sucker out (it just melted) i didnt know what to do. Then my dad came along, somebody told him that its easier to get to by removing the oil sump???? but no luck. Then i decided to get an angle drill bit, drilled a hole through the plastic of the crank sensor, screw in a hard screw with some weight on the end to wack backwards e.g old strong socket and tap it out or screw the screw in tightly as possible get a strong wide screw driver and using a hammer wack it upwards, the screw will bend and it draged the crank sensor out. I dont know any other way apart from taking the engin out and working on it?? my new crank sensor was a tight fit so i just sanded it abit. JUST TRY IT, HOW MUCH MORE CAN YOU DAMAGE IT IF ITS ALREADY DAMAGED! Hope this helps mate.
My wife said "it's the jeep or me?"
I will miss her beautiful face, legs, hair, blue eyes, sweet smell, amazing body and action. But hey, what the heck, I got a JEEP!
