Has anyone noticed the issue with their window going up unevenly at the start and finish but it still rolls up flush? Well, I found out one of the two of my bushings for the scissor lift appears to be missing and allows the assembly to wiggle in the track up and down at the rear. Does anyone have any idea what the part is called and if I can replace it by itself or if the whole regulator needs to be replaced? I can't find any reference to anyone else having to fix this issue either, but I have seen lots of windows with this weird thing where it doesn't want to go up evenly. I figured this out trying to adjust the window so it closes flush to the seals but there isn't a point in doing that until this bushing is sorted out...
