My 82 300sd has a problem with the ignition,steering lock where it wouldnt turn. Thought it was just time to replace after a few jiggling episodes. But then it occured to me that I dont get the problem if I dont lock the steering wheel when I shut it down. In other words if the steering wheel doesnt lock in place there is no problem, if it does, big problem. Is it posssible that the problem is in the steering wheel locking mechanism and not the cylinder? Anyone else had this issue? Thanks.
