Yup. Definitely need a purpose-made Pitman arm puller (not just a common 2-jaw gear puller) to remove the Pitman arm. The cheap fixed opening one I got didn't quite fit, so I had to machine the jaws a little bit wider.
I did actually get it off with a 2-jaw puller once, but I had to make supports to lock the arms in place against the arm, and tighten the forcing screw until I thought something would break. Had to add a healthy rap on the forcing screw to get it to pop. The Pitman puller works much better.

If you do the seal, also do the bushing. The pin that follows the worm gear can be
re-used if you drive it out and turn it 90 degrees to the wear.Make sure the shims on the lower bearings are
set up for the correct play.Pack the lower section of the box with wheelbearing grease, this will
keep the 90 wt from leaking out as your new seal dosent really seal.......trust me!

So I pulled the steering box out after most of the 90 wt leaked out overnight. The seal was dry! Turns out the leak was from the front cover. I guess my new seal and bush will be saved for the next TR3. I dropped the main body back on the chassis today. Thanks for the tips! Bob

If you can get it, Penrite Steering Lube works well. It's a type of slumping grease that takes forever to fill the box, but stays put.
Whatever lubricant, the steering box has to be completely full or the upper race suffers.
