Drag Link Rubs On Wishbone

Post by MichaelPawelek » Fri Oct 15, 2021 3:23 pm

The drag link on the ‘25 slightly rubs on the top of the wishbone. Is the pitman arm too long? Wondering if this was changed in the past for “better” steering…,

Michael,
The length of your pitman arm has little effect that far away. How much caster do you have? That may have more to do with the rubbing by tipping the steering arm down.

Check your spindle arms. Earlier arms are straight and later arms have an upward curve. Your car should have the later ones with the upward curve (they come in right and left side). A local member just bought a Model T and had one of each type and his drag link and tie rod were rubbing against the radius rod on one side.

Both spindle arms have the curve. Thank you.

Took a look and yes a lot of caster and the spindle arms are pointed down below horizontal.

Do you have a good pit arm? Looks like a gap and washer in the photo.

I suspect it is because the car is lowered. The pitman arm dropped with the rest of the chassis and it is now low enough to hit.

Dan, Please explain. How can the car be lowered? Where do I look compared to a standard Coupe?

Michael,
sorry been real busy today getting ready for the show & swap meet in maricopa. Has your wish bone been beefed up? ( looks a little large ) If all the steering geomitry looks good? If your tie rod yoke is a 2721L and the ball is a2721A you can simply turn it over, if the yoke is a 2721 and the ball is a 2721B then you will need a tapered reamer to turn it over. If my phone ever down loads the pic of my fire truck I can show you what it should look like.
Craig.

The tie rod can be turned over to raise the draglink.
