Brass steering knuckle bushing IFS

The person sold me my 1995 4runner told me, I have to re-do the brass/bronze bushings in the steering knuckle. I looked at the part in the pictures, and to me looks like nothing more then some brass or bronze that I can easily cut on my lathe at the metal shop out of better material, like Oilite brass (or whatever we have left over in scrap from machining the A1 Abrams tank parts). While I was doing that, I wanted to drill a zerk fitting into the steering knuckle so I can just inject grease directly to the middle of that area without needing to dismantle anything.

Toyota want to charge like $46 for the one, then another $16 for the other. It would take me maybe an hour on the lathes, so saving over $100 is great, plus I upgrade the material to something a little more durable. I would like to carve them out have them ready for when I do the job, but I don't have any originals to take measurements on. Does anyone know the dimensions for these brass bushings ?

There are bushing in the control arms, but they're made of elastomer (rubber). There are bushings on the idler arm, but they're less than $3 each from Toyota (and others) (and are usually a polymer of some sort).https://parts.lakelandtoyota.com/sho...rimLevel=18380

So I would be interested in hearing more about this as well.

As far as making one's own, wouldn't you need dimensions to at least within 0.001" ? Even if I had a brand new set to copy, I'm not sure I could justify the time. But perhaps Stein can.

Oops! Erich Stein beat me to it. I referenced a 2wd spindle; here's a 4wd: https://parts.lakelandtoyota.com/sho...rimLevel=18204

$20 each: https://www.ebay.com/itm/9038130003-...-/182382065736 90381-30003

Now I understand. The bushings that carry the half-shafts.

I can machine down to .001" if I needed to, and also program the same machine to carve out 100 of the same parts. There are no parts on a 25+ year old used truck that would need to be .001" tolerant, even the head surface can be out .002" - .003"

Also... A 2wd 4runner ? Really? Who buys that? Why would anyone want that ?
