Which should I grind?
I'm in the middle of the disc brake conversion and just replaced the upper and lower ball joints got the spindle in tighten down the castle nuts and I can't turn the steering wheel...

Re: Which should I grind?
If you only need to take like an 1/8th inch then id start by grinding the a arm a little, that rolled steel is pretty tough. But are you sure you have the right parts here? Its just weird that its touching

Re: Which should I grind?
I'd grind the spindle. I wouldn't want to compromise the tubular A arms. Tubes are very strong until you introduce a stress riser such as a kink, dent, deep scratch or thin spot. The cast iron spindle wouldn't be compromised if you removed some material from that location.
Correction - that's a factory stamped A arm. I'd still grind the spindle. The rolled portion of the A arm contributes to its rigidity. You're not wrong. The suspension and steering should not bind and fully articulate through its range of travel. |

That's what I thought, that A arm was designed to be as minimal as possible and still be strong, I don't want to start taking out material. I will grind the spindle a little and see if that gets me there. |
Re: Which should I grind?
I would take a little off of each.

If they are factory spindles I wouldn't hesitate to remove the material that is causing your problem. If they are aftermarket then I would return them as they may have been mis- machined. |

So they have a western logo on them but it looks off, like maybe a spin cast of a western spindle? Here are some photos...

Re: Which should I grind?
If mounting hole was further in towards frame it would have an effect on camber. Also I’ve had a few sets of spindles rub like that when suspension isn’t loaded. Never grinded anything and never had issues.

Are the shocks on it? They will not let it get but so far down.
