Econoline Front Axles


Other than a slight change in the weight bearing capacity, the front axles on all Econolines are the same and are interchangable.

Spindle Bolts - King Pins

Two different king pins were used: 1961-1963 and 1964-1967.

1961-1963 King Pin Set

Standard king pin set, Ford # C1UZ 3111-C

0.010" over-size king pin set, Ford # C1UZ 3111-D

1964-1967 King Pin Set

standard king pin set, Ford # C4UZ 3111-B

There are no oversize king pins for 1964-1967.

NOTE: Replacement 1964-1967 king pins usually come with the locking pin groove cut too deep, which will cause the pins to wear out prematurely. The thickness of the king pin at the groove should be 0.662 inch. The bad pins have a thickness of 0.644 inch. The correct groove can be cut on the other side of the pin if you have the right tools.

Alignment Specifications

Since the axles were the same from 1961 to 1967, the specs should be too. My guess is that 1967 specs are the best to use for all years. I'll keep checking into that.

Caster angle (backward tilt from true vertical)+3 1/2°± 3/4°+5°± 3/4°+5 1/4°± 3/4°+5°± 3/4°
Max difference between both front wheels 3/4°1/2°
Camber angle (top of wheel tilts out)3/8° ± 1/4°3/8° ± 1/4°3/8° ± 1/4°1/2° ± 1/4°
Maximum difference between both front wheel camber angles 1/4°
Tread and Toe
Front Tread = 60 inches
Rear Tread = 60 1/4 inches
Toe-In (amount wheels turn inward, towards each other, at the front)= 3/32 ± 1/32 inches
Toe-Out on turns = 21 1/2° (Angle of inside wheel when outside wheel is turned 20°)
