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...
So the question is do I grind down the spindle or the upper A arm?

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?
So I talked to a tech at POL, he said that because the suspension is at full droop that it will contact and it shouldn't with weight on it... I don't get it, every other car I have worked on you want everything to move for the full range of the suspension travel, if I sink one of the front tires in a pot hole I don't think my steering should lock up... Am I wrong?

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.

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.

Re: Which should I grind?
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...
Here is where the upper ball joint goes... and Here is is with an overlay of where I think the hole should be... also the red arc shows where the A arm is contacting it.

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.

Re: Which should I grind?
Are the shocks on it? They will not let it get but so far down.

Re: Which should I grind?
Yeah The shocks are still attached, I ground the passenger side spindle down so now it clears the upper, I just need to do the drivers.
