I have read many posts in the archives about freeing the steering on wagon running gears. So, far I have soaked each side with penetrating oil and have used an acetylene torch rosebud for heat. I really can't get everything hot at once. Used a sledge hammer on the steering arms to attempt to turn the vertical shafts. The two steering shafts are 1.5" in diameter which are inside about a 2" tube with 1/4" walls. I have taken the tie rods off. Center/tongue is not froze. Just each wheel. I really do not want to cut the wall of the outer tube open - just feel that it would weaken them to much. I recently JB welded some 6" lengths of 2" PVC pipes on top of the 2" outer tubes which I filled with marvel mystery oil and acetone to provide 24 hour soaking. After a couple weeks still no progress. So far I have not beat on the outer tube or the top of the shaft. I sometimes wonder if I could beat on the outsides to stretch the metal, then beat on the sides 45 degrees away to somewhat reshape the tube. I am about ready to take it to a welding shop with a BIG rosebud. Any more ideas??????
