Ok I looked at my 1957 Motor's Flat Rate & Parts Manual to see what they were calling these parts, since apparently the factory parts manual isn't good enough. Here is the results for some of the 49-57 cars and trucks:
Buick
Steering Knuckle, Knuckle Arm (Wheel end)
Steering Gear, Pitman Arm (steering Wheel end)
Cadillac
Steering Knuckle, Knuckle Arm (Wheel end)
Steering Gear, Pitman Arm (steering Wheel end)
Chevrolet
Steering Knuckle, Knuckle Arm (Wheel end)
Steering Gear, Pitman Arm (steering Wheel end)
Chrylser & Imperial
Steering Knuckle, Knuckle Arm (Wheel end)
Steering Gear, Pitman Arm (steering Wheel end)
Continental
Steering Knuckle, Knuckle Arm (Wheel end)
Steering Gear, Pitman Arm (steering Wheel end)
De Soto
Steering Knuckle, Knuckle Arm (Wheel end)
Steering Gear, Pitman Arm (steering Wheel end)
Dodge
Steering Knuckle, Knuckle Arm (Wheel end)
Steering Gear, Pitman Arm (steering Wheel end)
Ford & Thunderbird
Steering Knuckle, Knuckle Arm (Wheel end)
Steering Gear, Pitman Arm (steering Wheel end)
Hudson
Steering Knuckle, Knuckle Arm (Wheel end)
Steering Gear, Pitman Arm (steering Wheel end)
There is one difference - Power Steering uses a pitman shaft
Now for some Trucks
Willys & Jeep
Steering Knuckle, Knuckle Arm (Wheel end)
Steering Gear, Pitman Arm (steering Wheel end)
Chevy
Steering Knuckle, Knuckle Arm (Wheel end)
Steering Gear, Pitman Arm (steering Wheel end)
Dodge
Steering Knuckle, Knuckle Arm (Wheel end)
Steering Gear, Pitman Arm (steering Wheel end)
Motor uses pitman Arm for steering end, but certainly not steering arm on the knuckle end.
I use what the OEM parts Book calls for 1947-56 FF PW Knuckle Flange, Knuckle, Knuckle Arm and Steering Gear Arm. You can refer to the Steering Gear Arm as a Pitman Arm if you like, but if you use Steering Arm for the Knuckle Arm, you'll get the appropriate response.
By the way, my E-MAIL ADDRESS is under PW Friends!
