just reposted a another questions here

00 crown vic police package

The pitman arm wont come off the steering box bolt. Its stuck on the spline and im afraid if i hit it, it may damage the teeth.
I obught 2 pitman removers but they are too narrow and the other dont fit betwween the spline to grip it..its too thick .

How can i remove it off the spline bolt without damageing it. I sprayed pb blaster to hopefully losen the rust on it…should i bang on it? or wedge a crow bar between the shaft spline?

I have never had trouble getting a pitman arm off using a pitman arm puller. you need the kind that has bolts to adjust the width of the puller. tighten the bolts around the arm as tight as you can w/o breaking the bolts off. put as much pressure as you possibly can on the jack bolt then hit the end of the bolt with a big hammer several times. you may have to turn the jack bolt a few times and hit it again before it finally comes off.
