Is it possible to replace the audio from a clip that is already edited on the timeline?

The original raw clip is a 17 minutes long interview,  I replaced it's audio for an external mic audio they used, but the mic's audio was terrible (constant buzzing background noise and low general audio).

I edited it like this anyways and the final sequence is now only 7 min long.

But a friend solved the noise problems on Audition and I replaced the new audio on the sequence with only the long interview. So now I have the new version with the good audio but only for the 17 min long original video.

Is it possible to replace the audio for the other sequence without having to do it manually? Since that means having to edit everything again.

I already tried "Replace With Clip > From Source Monitor, Match Frame" and "Replace With Clip > From Source Monitor" but it did not work, but I could probably have done it wrong since I am not that experienced in Premiere Pro.

I also tried just synchronizing just in case, but it also did not work.

I feel that there is an easier way to do it without having to edit it all over again.

Save your project and make a copy in case it goes wrong. Select the audio footage you used for your edit in the project panel, right click and select 'Replace footage' and replace with the new improved version. This should work if the new audio is the same length and has matching timecode.
