I have done two things to my shower door to solve the problem. First, place a straight metal bar (like a yard stick) across the top to see if the center round piping is level with the fixed piping. Mine was not and I placed two straps at the edge of the piping, placed a 2 x 4 between them and used a small jack to straighten the pipe. Somewhere on this forum are photos showing how to do this. Secondly, I found that the rollers were slightly worn and would not allow full adjustment. This was solved by installing new rollers. Now it rolls perfectly. I think it is important to travel with the door open and secured with the thingy shown above. Traveling with it closed puts too much weight on the piping. Hope this helps.
