Window not coming down upon entering

[sb01box]

my 01 just underwent door lock repair and now it seems that the small drop down of the window is acting up. just like this thread.
Is the root problem the outer sleeving loosing it's strength and making the cable system sloppy? if so, by taking the slop out of the system by only pulling on the inner cable and placing a spacer without addressing the outer sleeve a very short term solution? more permanent fix would be to make sure that the outer sleeve does not further degrade (collapse)?

thanks in advance
