Sliding glass door opening and closing with difficulty

Home Owner from Bernardsville NJ
It is difficult to open this sliding glass door without doing quite a bit of pushing and pulling. It seems as if the rolling mechanism at the bottom is worn out. It makes a grating sound when it slides. A little WD40 helps a little; but I think that some parts need replacement. Can you please help me out?

Hello, 

As we discussed, we'll need a picture of your roller removed from the door. Take a look at the video for help removing the rollers. Thank you!
