Drivers door window guides

Noticed my drivers door window has been getting slowed down when it reaches 3/4 of the way down. Pulled the door panel off, and it looks like the guide on the front side (side closest to front of truck) has bent. Not sure how or why...?

I'll start looking for some new/used parts, but anyone have info on:

• Why this might have happened?
• Steps to replace the guides?

 

I have been thinking of replacing them on all four doors. I am getting the truck painted. It will be better to remove them myself, so I will be waiting for a reply from those that have done this before.

 

Do you have issues with yours?

 

No Issues, just want to take them out and replace them. Nothing looks worse than new paint and old rubber/trim pieces.

 

Ah. I'm speaking specifically about the metal guides, but the bend has made the window chew up the rubber...

 

OK, don't mean to de-rail your thread.
