The wheel turns around like that is exactly what they do without a stop on it. Yes the pin through the quadrant is another primitive part that does wear . Big job to set it up with bearings, I did it on my mates 11 years ago and it is still working fine. I was talking to him this morning about it and he loves it now he doesn't have to get off and fix the wheel. Tyre rubbing on the king pin , might have to put a washer on the stub axle to space it out a bit further. To get it to turn left a bit better you may have to adjust the rod coming from the triangle quadrant to the top of the left king pin. Mate and I spent many hours earlier this year just getting the steering set up properly on his making new bushes etc, but now he is super happy with it, reacons it will see him out
