Question about 1989 GMC C1500
I bought a pitman arm puller(a cheap one) and the pitman arm is on there so well that the pitman arm puller top hooks broke. Is the arm just siezed to the shaft, or is there a secret to this style of pitman arm? I was turning the bottom screw on the puller using a 1/2" drive ratchet with a cheater bar on it, and it would not budge. If I put heat on it, I will melt the rubber boot. Will heat wreck anything else in the steering box I don't know about?
This is how I do it. I spray alot of PB Blaster all over the connection and take a large hammer and hit the side of the pitman arm and keep spraying and hitting. It'll come loose and fall off. You have to break up the rust "welding" it together.

Tips for a great answer:
Things You'll Need
the vehicle on a level surface and make sure the front wheels are pointing
straight ahead. Make sure the vehicle is in park (or in gear if you have manual
transmission) and set the parking brake.
the pitman arm from the steering box from underneath the front of the vehicle
by turning the holding bolt in a counterclockwise direction with an adjustable
wrench. Place a pitman arm puller (available at auto parts stores) over the
pitman arm and tighten the nut on the puller in a clockwise direction with an
adjustable wrench until the pitman arm loosens from the steering box shaft.
Remove the pitman arm and the puller.

compartment with an adjustable wrench in a counterclockwise direction.
a torque wrench on the steering shaft and turn the wrench one complete turn.
Make sure the torque reading is approximately 2 inch pounds. Tighten the
adjusting nut on top of the steering box (it comes out of the center of the
lock nut) in a clockwise direction with an adjustable wrench one half turn if
the torque wrench reading is too low. Loosen the nut in a counterclockwise
direction if the reading is too high.
the steering shaft with the torque wrench again. Make adjustments to the
steering box adjusting nut as described in Step 4, if needed, until the correct
reading is obtained on the torque wrench.

pitman arm to the bottom of the steering shaft on the steering box. Tighten the
