32 mm 1/2 inch drive on an electric impact.
15 min. of map gas torch, and it finally came off.
buy a new pitman arm too for 36.00 from morris 4x4. don't bother struggling to get the old one off. your time is valuable.
when my new pitman arm comes, I will be doing that job myself. I started it this last weekend and after giving in to the pitman arm being seized on, I bought a new one for this coming weekend.
