I have a similar problem, but have not replaced anything. My 99 body is stock, but last week I noticed a bigger gap at the top. The gate, when closed is TOO HIGH in the door gasket and I can see daylight all along the top of the opening, and it snags the roof when opening or closing. I tried all advice given here, one adjustment at a time. I have tried adjusting after removing the gas springs, . I am guessing the hinge pins are worn (?). but have not come across ANY info on this. This is one I can neither figure nor wrestle for a win. Your help would be appreciated.
