windows hard to roll up

[Clyde65]

Hey guys, I have no ideas here, The windows in my truck were power( YUK!) that didnt work or work very well when they did. I changed it back to roll ups with new weather stripping, glass and all that. rolling the windows up is like wrestling an alligator, very hard to roll, which in turn has stripped the window handles. any ideas?

The window is free to move up and down ( checked before regulator was in). One regulator is a newer one and the pass side is stock.
