What did you use for lube on the bushing?
Using High temp Wheel bearing grease eliminates issues.
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.
