Do you need to remove the whole logic board to from the housing to replace the headphone jack on a MacBook Pro 15” Retina mid-2014? It seems that repair guides for this specific repair are very scarce. Found one for the 2012 version, but not sure if it applies to 2014 version.
You can’t find guidance because the headphone jack is not a user replaceable part. It’s a fairly challenging through-hole soldering job on the logic board itself, for which professional tools and experience are needed.
