This is still a very foggy swap.

Swapping 1948-1952 48-52 Ford F1 (not F100) spindles on a Model A axle.

Same kingpin diameter.

Some say yes. Others say no.



1948 F1
Caster Degrees (maximum variation between wheels is 1/2 degree) = 2 1/2 degrees minimum to 4 1/2 degrees maximum

Camber Degrees (maximum variation between wheels is 1/4 degree) = 1/4 degree minimum to 1 degree maximum.

Toe-in (in inches) = 0 inches to 1/16 inch in

King Pin Inclination (degrees) = 8 degrees +/- 1/4 degree.

Preferred Caster ... +6 3/4 degrees
Preferred Camber ... +5/8 degree
Toe in ... 1/16"

Looks like it will work to me? What is your educated guess?
 
The numbers look ok.

I have some f2 spindles, so I would like first hand confirmation that they work.

Mart.

As long as you have the F1 spindles, have you considered using the Bendix style F1 brakes? They're considered to be better than the Lockheed brakes used on the passenger cars. (I'm using the F1 brakes on passenger spindles and I had to get "odd ball" inner bearings and seals.)

The "F1" brakes I referred to are the '48 to '52 variety. They're the "self energizing" style and they bolt to the '37 to '48 spindles. They use an 11" drum, and to use that, you have to use the F1 hubs (hubs and drums separate) but the hubs need a special bearing and seal to mount on the passenger spindles which I'm using.

'53 up to ?? (F100) are a different animal that I'm not familiar with.

'48-'52 F-1 and '53-'56 F-100 backing plates and brakes are the same.
On the F-1 hubs the wheel mounting flange is spaced about 1/2" further out than
on the F-100 hubs. Either can be used as long as you use correct drum for the hub
you are using.

F-100 drums are still available as aftermarket replacement parts. F-1 drums
are only available as reproductions from the antique parts dealers, they are
usually more expensive for that reason.

Ford made F-1 pick-ups from '48-'52. The earlier 1/2 ton pick-up spindles and brakes were the same as car spindles.

F-1 spindles have a bolt on L/H combo steering arm and an integral R/H steering arm with only one tapered hole.

The earlier spindles will have integral steering arms on both spindles and
two tapered holes on the R/H steering arm.
 
Ain't no '46-8 Fi spindles...
'46-7 pickup use ame spindles as '42-8 passenger, all arms forged integra, socket for cross steer on right spindle...'48-52 F1 are set up for drag link side steer.
