One thing I might say, even though to late now, is: I wouldn't clean out the subframe where the joint pressses in. Did that for years till one bit me.
The normal reason for replacing the joint is a clunk when the longitudinal loading reverses. With a clean subframe the bushing can move within its containment maybe a miilimeter. This movement caused me a noise that wasted a day ten years ago.
Since then we leave them dirty except for brushing out loose bits.
