Looks like the stock front axle. If so the metal bushings in the spring could be all wore out, they are supposed to be grease regularly. Also, king pin bushings could be shot too, again they are metal and supposed to get greased often.

Somewhere I have the FSM for a 38 Plymouth, used to own one.

They say there is always the exception that proves the rule.
Don't be the exception.
