I found a problem with the tie rod ends, or more specifically the steering knuckles on the 3B. The tapers in the steering arms are too large for the tie rod ends. The first sign of danger was finding washers under the nuts during disassembly. Maybe my steering knuckles are from something else. The tapered holes are clean and don't appear to be modified. Do M38A1's have a larger taper on the tie rod ends? I know the threads and tubes are larger on an A1 but I thought the knuckles were the same.
