Hi, Working on antique cruisers is interesting. I've spent a week soaking and heating an fj-40 power steering box pitman arm ( using a 3 foot bar and OTC puller) , just about to give up when it broke loose. I'm building 3 boxes. Decided tonight if the next was going to take a week I needed to get started. This box took no heat ,hammering or oil and broke loose in 5 minutes. The boxes looked almost identical in rust and crud on them . Go figure. Mike
