Is the column or bearings rusty? I would say to spray the bearings with a rust penetrate. Start to rock the shaft back and forth to free up the bearings. You will have to disassemble the column if it does not move. The bearings will have to be replaced anyhow. Can You tilt the column? Remove the turn signal switch and take out the bolts holding the collar to the column. the bearing should slide on the shaft. Lube the shaft if it does not. NICK L72
