My tumbler has broken twice in the last two years. Yes, the design has a little to do with it, but the starter momentary switch position has become very difficult to turn to and I was wondering of anyone else has had this problem? The parts are pretty cheap to replace, so I imagine that it is not uncommon. The little pin on the end of the tumbler is what breaks off. I can actuate the rod going down the column by hand for every position except to start it. I have a new switch, which I guess is the problem, but am not entirely confident. I have replaced this switch long ago in another 85, but it did not have a tilt wheel option like I do now, and I wonder if that may have any affect in causing my current woes. Any insight is welcome. I am at my second house with limited tools (limited only in that I don't have a lot here, there are hardware and auto stores to buy what I need) and working on a gravel driveway. Many would say, "so what?" but I like to work on the truck on my own terms, not 400 miles from home, especially if I need to tear something (steering column) way apart.
