1972 Highboy hydraulic Steering Bushing
Ford Trucks for Ford Truck Enthusiasts
P/S was not available for 4WD's until 1973, so it's been swapped in...but from what?
Assuming it's Power Assist P/S from a 1973/77 F250 High Boy, there are two different types of Power Assist. The parts do not interchange!
--------------------------------------------------------------------------------------------------------------------------------------
1973 F250 4WD, 1974 F250 4WD before serial number T80,001 use GARRISON Power Assist P/S.
The Garrison P/S control valve has two short draglinks attached to it, one at the front (3 1/2" long), one at the rear (5 1/2" long).
Each draglink has a non replaceable stud/ball joint swagged into it. The stud of the forward 3 1/2" draglink fits into the Pitman Arm.
If the ball joint is worn, the 3 1/2" draglink has to be replaced: D3TZ-3304-D.
----------------------------------------------------------------------------
1974 F250 4WD from serial number T80,001, 1975/76 F250 4WD, 1977 F250 4WD before serial number Y20,001 use BENDIX Power Assist P/S.
The Pitman Arm with Bendix P/S fits into a replaceable ball stud located on the forward section of the control valve. There is a rubber boot surrounding the ball stud.
There is a coil spring associated with the ball stud, fits in front of it.
The spring collapses and/or the ball stud wears, causing it to flop around, the steering becomes loosy-goosy.
If this is the setup you have, you will need the ball stud repair kit (D4TZ-3A533-A) and the actuator kit which includes the coil spring (D4TZ-3783-A)
All these parts are obsolete, but can be found NOS.
Why would you need it...if the truck has swapped in P/S? Does the Pitman Arm connect to the Power Assist P/S control Valve?
Or does it connect to the sector shaft? If it connects to the sector shaft, the truck does not have P/S, has M/S or some other type of P/S was swapped in.
I HATE SWAPS! You wanna know why?
Peeps make changes, do not record what the parts come from, then when something breaks, they waltz into the parts dept, lay a bunch of greasy parts on the counter...say what are these from?
It was bad enough at the parts counter, but at least you could "eye ball" the parts, compare with new parts.
On the internet it's worse, because without an actual photograph of how the Pitman Arm is connected, it's impossible to help.
Post #25: I listed both types of F250 4WD High Boy Power Assist P/S control valves, explained how the Pitman Arm connects to each type. Without further info...or a pic, there is nothing else I can do.
