I am having a difficult time with removing the pitman arm from the gear box. I am unable to loosen the three bolts that hold the gear box. i have sprayed these bolts with pb blaster and letting it sit over night. Any suggestions would be appreciated on how to break these 3 bolts free. i have a 1/2 inch drive breaker bar (25" length) but can't seem to get a good angle. I am thinking of getting a long 1/2 inch extension to attach to the breaker bar. Once i can get these bolts loose i should be able to get my pitman arm puller in a better position to break the pitman arm loose from the gear box.

 

If you are saying to add an extension between the socket and the breaker bar, I would not do that if not necessary. I would add an extension to make the handle on the breaker bar longer to get more leverage. Be careful something might break.
