When I broke my stock lower front A-arm, I replaced it with OFNA's CNC aluminum unit.

The arm was very nicely finished and the blue-anodizing was just nice eye-candy!

I had two problems when installing the arm:

1) The hingepin may not fit easily into the easily... if this is the case, use some fine-grit sand paper to sand the ends of the hingepin (chuck the pin in a dremel/drill if you have one for this) and you should be set.

2) The other problem was that the aftermarket arm did not work well with the stock knuckles. The problem was that the new arm had a raised area where the ball is captured (pictured) and this portion would hit the knuckle and prevent full extension of the arm and full steering. I tried the aftermarket knuckle which solved the extension problem but not the steering one.

My solution? I dremeled the stock knuckle to remove the portion obstructing the free movement of the parts. Click on the pics and in the larger version you will see I've circled the portion I am referring to.

The mod worked perfectly and now I have full extension and steering *WITH* the added strength of the aluminum arm.

It's important to note that you have to remove material from the inner edge, rear edge and some from the outer edge.

I've since upgraded to titanium center braces and these are supposed to be next to indestructable - but I still run the upper aluminum brace just for that added bit of assurance. :)
