I don't think so. I've tried adjusting them and thought I had the window all lined up finally, but it's right back where it was before. I think I actually even rebuilt them a while back. I have some noticeable cracks going on at my rockers at the back edge of the doors as well, so guessing it's a bit weak. Watched the door gap when I lowered it off the lifts as well and could see a bit of flex.
