Doing a Drum to Disc conversion on a 1952 Ford F3 Parcel Van.
Replacing nuts and bolts as I go along and have a question about a piece of hardware...
Located on the axle, just behind the bottom of the king pin is a 3/4" nut with a square head bolt going through the casting of the I-Beam.
Looks to possibly be an adjustment to limit the amount of swivel rotation on the front tire so it doesn't rub in the wheel well.
Since the shock absorber and lower bracket has to be reversed for the disc brake install, the shock is adding more "meat" for the stop adjustment to hit sooner than the original setup, being on the other side of the I-beam now.
Any tips on adjustment or if it is no longer needed would be appreciated...
Thanks.

 

Without a pic this is just a guess, but it sounds like the through bolt that holds the king pin in and indexed.

 

I was off on the description.
The bolt is located on the bottom half of the spindle assembly and as the wheel is turned, the flat of the bolt head contacts a flat spot on the I-beam.
It acts like an adjustable stop to not allow the wheel to turn beyond a certain point. Maybe if it goes too far, there is a lock-up of the linkage.

 

If it is the hole in the end of the axle in the attached pic, right behind the spindle, that is the through bolt for the kingpin. It does have a large/extended nut that acts as a steering stop.

 

Hi,
Here's a pic of the bolt we've been talking about...



See how it is part of the lower spindle yoke...

 

It appears to be something unique to parcel trucks, maybe because of their flat-sided "fenders"? Does appear to be a turn stop.
