Curious......... How can you get screeching if there is grease in the bushing?
The iron percentage content is to keep the bushing from wearing and keep the hole centered.
It's not the Chinese made units as I have pilot bushings in stock that are over 20 years old and have a magnetic content from Pioneer.

Hi there. To be dead honest, I did not use any lube whatsoever on the original Chinese bushing because true Oilite is not supposed to be lubed. As this was my first time ever doing a project like this, I did not realize that this Chinese bushing was not true Oilite, so I installed it lube-free and went to town.
If I had of known about the high iron content in the first place, I would have either (A) lubed it with high temperature wheel bearing grease like you suggest, or (B) thrown it in the garbage and bought a true Oilite bushing.
As it stands at this point, I chose option "B". And I did not put any lube on the bushing once again, because this time it is a true Oilite bushing, complete with vacuum-impregnated lubricant.
I called Beemer Precision, the makers of true Oilite Bronze, and they assured me that if in fact my new bushing is genuine Oilite (which my new bushing definitely is), that no additional lubricant is necessary. As the bushing begins to warm up, it slowly releases its factory-installed lubricant.
I actually purchased an extra true Oilite bushing from Autogear just to have on the shelf. It is amazing to see the "film" of lubricant through the zip-lock bag it is stored in. The bag looks quite cloudy.
Conversely, I kept my original offending Chinese bushing and also put it into a zip-lock bag. There is absolutely no sign of a lubricant whatsoever.
So, as I have now learned, I guess you could get away with some wheel bearing grease on a high-iron (magnetic) bushing, or go the true Oilite route.
Knowing that the true Oilite offering is permanently lubricated and is "softer" on the transmission input shaft, I would definitely stick with the Oilite bushing.
