Im doing a partial front end resto on my 1990 k2500, but cant get the torsion bar, torsion key or lower control arm off. Ive tried pb, wd40, no name penatrating lubes, rust evaporaters, just about everything i could think of atleast 3 times each, and tried to beat on the torsion bar from the back of truck going to the front with a sludge hammer, tried again with come along pulling the lower control am forward, even tried a jack held up horizontally hasnt moved at all! Almost getting ready to just give up and move on to something else, but it will bug me forever knowing i couldnt get it out. Please let me know if you know of any tricks or other methods i could try!
