problem with replacement window rollers
Update: The quarter window is back in and working well. It travels up and down smoothly and the motor doesn't sound like it is straining. Fiddled with window adjustment but final touches will wait until the new top goes on next winter. If any of you ever remove old rollers don't throw away the cupped washer if it is useable. It may be a better piece than the one that comes with replacement window rollers. I'm saving mine in case I have a similar problem on another window.
