You fellows won’t believe this: I’m trying to remove the rear yoke nut to replace the pinoin oil seal on my Gremlin. It’s been there for 41 yrs. I’ve tried a portable electric lug gun which has done the eagle @ 120 lbs torque but I realize I'm dealing with over 200, pneumatic air gun @ 120 lbs, breaker bar with extended pipe to the floor for leverage, proto heavy duty torque wrench reversed direction, careful but solid hammer blows to the breaker bar, map gas heat applied for 10 - 20 min a few times, penetrating oil, I’ve gotten on the floor and braced myself and pushed the breaker bar with my legs as well as pulled it with both arms from the other side. My next idea is to line up the nut with the skid plate of the Eagle & to run a hand hoist with hooks between both cars. If I put tension on it for a couple of days it may loosen it up if it doesn’t strip the bolt first.
