Good idea to add a photo, Bill
Not only does it look like Vickie's are worn down or missing, but you can see where it has started to cut into the upper part of the hinge body in her last photo. Luckily that should not come into play once the new balls are in there.
Vickie, I would definitely get a set of these and install them before I did anything else. Maybe that is all (or most) of your problem. Certainly it's hard to judge the rest of the problems (if they even exist) without the balls in the hinges.
(I was thinking that *maybe* the
Perris Pacer hinges did not use the balls, but I highly doubt that, especially looking at that last photo.)
