F 250 2WD Pickup V8-351 5.8L VIN H 4-bbl HP (1985)
3.
INSTALL COTTER PINS IN ALL THE STUDS.
4.
Drive the vehicle. If it no longer drifts, then it can be assumed that the rubber was causing the drift. If it continues to drift, the condition is NOT
being caused by the rubber ball sockets.
5.
In either case, do not replace the steering linkage.
Reinstall the linkage as follows:
F Series and Bronco
1.
Ensure the pitman arm and wheels are in the straight ahead position. (The pitman arm is exactly straight ahead when the clear vision is at 0~.)
2.
Lock the steering wheel straight ahead and loose assemble the steering linkage to the pitman arm and then to the spindles.
3.
Being careful not to change the position of the pitman arm, torque the steering linkage nuts to 65 ft.lbs. (88.1 N-m) The recommended sequence
for tightening is: 1) the pitman arm, 2) the right side spindle and 3) the left side spindle.
4.
Install all the cotter pins by advancing the nut to the next castellation.
5.
Adjust the toe-in if necessary.
Econoline
1.
Ensure that the wheels are in the straight ahead position.
2.
Loose assemble the steering linkage to the spindles and the pitman arm.
3.
Being careful not to move the wheels from the straight ahead position, torque the steering linkage nuts to 65 ft.lbs. The recommended tightening
sequence is: 1) the right side spindle, 2) the pitman arm and 3) the left side spindle.
4.
Install all the cotter pins by advancing the nut to the next castellation.
5.
Adjust the toe-in and reset the clear vision if necessary.
The above procedure will eliminate any of the drift being caused by the rubber ball sockets. If the vehicle still drifts, refer to Section 19 of the Light
Truck Shop Manual for further diagnosis.

A side-to-side caster difference can contribute to a vehicle drift in the direction of the side with less caster. If the difference cannot be corrected by Shop
Manual procedures (greater than 3/4~ difference), a service kit (for use on vehicles with forged axles) can be used to increase front wheel caster angle on
either or both wheels to balance the caster split. The kit contains complete parts and instructions needed to modify the front radius arm and mount a
metal cam on the bottom of the arm. The kit can increase caster from 1/2~ to 3 degrees, in 1/2~ increments. It is not designed to decrease caster.
Vehicles with stamped axles cannot utilize the caster kit, but can be serviced with a different procedure.
To increase front wheel caster angle of subject vehicles with forged front axles to balance the caster split, the following procedure is suggested:
1.
Remove radius arm from the vehicle as shown in Section 14-21 of the Shop Manual and choose appropriate paper template contained in the
service kit and identified by vehicle model.
