urethane bushing longevity (ever had to replace one?)

im honestly curious if urethane bushings (like powerflex) have EVER had to be replaced due to age or wear.
i see a couple warnings of squeaking and increased noise/vibration/harshness, but it seems like a lot of that is from improper installation (powerflex has confusing standards for left/right, and people dont seem to use enough copper anti-sieze lubricant)

do they just last forever?

I saw on other car forum (non-BMW), someones made their own polyurethane bushing using polyurethane cartridges brought from HD, and those home made polyurethane bushings hold well, the only issue is, it is white color.

I made sway bar bushings about 8 years ago before anyone was making them for E39's.
Bought them from Summit Racing then machined them to fit the brackets and bar.
The lube that comes with them is very sticky synthetic grease. It has the consistency of cold molasses.
They don't squeak.
