Window regulators sticking or binding

[farmallgray]

My manual windows are getting hard to roll up and down. I had put all new felts and weatherstrip in a few years back when I put the new doors on.
I figure something needs lubed or adjusted. I'm just wondering if there is something in particular I should be looking at or paying attention to. Or is there something that wears theat needs replaced (besides replacing the whole regulator)?

I tried doing a search, but mostly what I found was about converting to power windows.

Spray the felt channels with a dry silicone spray, not WD-40, grease the sash rail and stationary door roller tracks, grease the regulator gears, lube the scissor joint, and verify the glass channels are properly adjusted.
