Lower control arm question

Hi everyone. Sorry if this is a redundant question but I couldn't find anything. It may be a dumb question lol! I'm rebuilding the suspension on my duster. I removed the lower control arms and removed the pivot pins. They pressed out without issue and the bushings were old but not in horrible shape. I've watched a bunch of videos on how to remove the outer shell from the lower control arm. It seems there's only two options: weld a washer to the cups and press them or chisel them out.

Here's my question: if the outer shell looks good, do you have to remove them?

...not the best pic but the insides aren't scratched or scored. Still in the cleanup process...0

Any advice is greatly appreciated
