I am assembling the front end on my 24 roadster and it seems as if the wishbone is too short, causing the axle to be straight up and down instead of the normal tilt toward the back. This puts a lot of pressure on the ball & socket and also the leaf spring shackles. I have replaced the wishbone and my spring perches are correct left & right. Any advice is appreciated. Thanks David
Try flipping the wishbone. Often the car has a bent frame, sagging frame, or bent engine pan. Sometimes the easiest fix is to bend the wishbone so that you get enough caster in the king pins. Other times you must fix each component.
Because of the tapered nut sockets, I don't think a late style, below-the-axle wishbone will flip like the early one will. Do you have the correct crankcase?
Have you checked to make sure the spring perches are on the correct side? Reverse camber of the front axle would push the bottom of the front axle forward doing what you described.
This happens sometimes. I believe it's usually related to a front cross member being bent or otherwise distorted. The cross member miss-locates the spring, the spring miss-locates the axle, then the wishbone doesn't fit.
Post some pictures, particularly of the front crossmembers area -and-the wishbone socket on the crankcase.
The bad roads of the old days were tough on that part of the crankcase. It was always getting a bust in the guts there. Especially four dip pans. A wonder any of them are good.
