The pins shear off in an accident,to keep the column from driving into the drivers chest. I wouldn't say it just a safety feature. holds shaft in the correct place.there is enough free movement in the steering cup. It slide in about 6 inches. it is a machined fit.I do recall it took a little persuasion, It could be rust inside the shaft or the bonding agent hanging up. place larger end in vice,vice grips on smaller end. heat with propane torch, hold vice grips bump vice grips a jaws. If its really tight heat the outside maybe 5 min,not red hot and shock it with water.may take a few tries. As far as injecting hot glue. when apart you will see 2 groves around the inside shaft.line the holes up with grooves. better yet the videos I do belive they gave the shaft lengths. Have shaft placed so you don't have to move it.preheat shaft,inject,allow to cool. I do believe you have the idea.
