I first tried my 3 jaws regular puller. Not suprised it didnt budge. Being on the steering box, don't wanna ise heat or just beat it with hammer. My friends jeep i had to put a slit in it. I stopped just shy of cutting all the way through and put a fitting wedge into it and it fell off. But that was last case scenario. To my amazement i picked up a pitman arm puller for $20. I cranked it as much as i thought it could stand and then just gave repeated light taps for about a minite.
