    A57E5B66-214E-48E1-9141-4DE9A5C503EE.jpeg I have a question about how the yoke end of a Ford wishbone is welded to the tube end. Is it just a butt weld or is the yoke partially in the tube like a drive shaft yoke? I need to change the caster because I’m flipping them upside down to lower the ride height.

    Can't answer your question exactly,
    but I have seen people use a Pie Cut to change the Caster.

    How much angle to you need ?

    Flipping the bone’s upside down should lower the car an inch or so. It looks like that’s what people do when going with a suicide front end. But the caster needs major changes

    Are the ends just butt welded to the tubes?

    Can't you just stick your finger in the hole and feel how far it goes into the tube ?:confused:

    Yeah, I guess I can cut the spring perch bushing out and see what’s going on with it.

    If you flip the ends you will have the thinner / weaker end supporting the axle.

    The forged ends stick about an inch or so into the wishbone. You should be able to explore the hole and see the end. As long as you are past that, you can pie cut with no issue.

    By flipping the yoke and adding 2 degrees more caster, it lowered the car another 1-3/4”.

    the forged pc has a bung that fits inside of the tube. 20200915_212405 (1).jpg

    Just FYI for other readers, the earlier wishbones (32-34 for sure) do not extend into the tube.

    For the record, these wishbones are 1941. They are longer, have larger tubes, and thicker yoke ends than ‘32 bones.

    I don't think I would stray from having more material under the axle!

    IMO you are raising the front of your car by doing this. The distance from the top of the axle where the spring perch/radius rod flange mates with the axle to the center of the spring eye is going to be increased, thus raising the front end of the car.
    The amount it is raised is the difference in the thickness between upper and lower flange on the radius rod.

    hi,my wishbone is not 32/34 and I extended the length to bring the ball mount farther back to meet the trans cross member,If pictures would help let me know.

    raising the axle up is actually lowering the car.

    It’s like drop spindles. They raise the spindle on the steering knuckle to lower the car.

    or like drop axles. They bend the ends up to lower the car.

    it doesn’t matter if the thicker part is above or below the axle. The eyelets are thru bolted with the axle, thus both eyelets are holding the weight of the car.

    If you are using conventional spring perches mounted through the axle then IMO you are wrong. If you are mounting the spring perches through the radius rods then you are right.

    If my setup was still conventional with the spring over the axle, this mod wouldn’t change the ride height at all. It would only lower the wishbone down closer to the ground. So am I still right?

    With spring over the axle if the thicker flange at the axle end of the radius rod is 1 1/8" thick and the other flange is 5/8" thick then reversing them as you are doing would raise the front end of the car by 1/2" while at the same time moving the radius rod at the axle end further away from the ground.

    If I was using that stock setup and if the yoke ends has zero caster built into them, then The half inch difference in the eyelets would move the axle 1/4” up. Which would move the ends of the axle up 1/4”. Thus a mini drop axle that still lowers the car 1/4”
