Default Power window really noisy/rough [video]

Any suggestions what I should repair/replace to make this power window sound less ... dying.
The motor works well. I lubricated all the window channels (as best I can) with lithium grease.

Who recommended the grease you used in the window channels? Plastics (rollers) and rubber degrade when exposed to ceetain petroleum based grease.

Replaced track rollers in mine, with correct lubricant.. noticeable difference; less noise, smoother, faster window operation.



Front door glass track "rollers" depicted here.. be sure and order extra spacers.

Thank you!

Edit: Can these parts be changed out without removing the window, or did you have to totally remove it? Thanks
