The other thing it could be, Joe, are the tracks. Clean them out. Dirt gets trapt in there and that will also slow down the free movement of the windows.
I remember the good 'ol days of when my windows would go up and down "fast", lol.

 

Also what grease did you use ??? some greases are pretty stiff I normally use a white lithium or even clear silicone for those ...

 

yea i used a can i white lithium
