Our patio door has been sticking since we moved in. It's getting progressively worse. We took it off and checked the rollers which were fine. The track seems to be the problem. Our 8 foot door has a long groove in which there is a long metal v-shaped track (wheels roll on this). When opening or closing the door, the track completely folds over. I looked online to get a replacement. The only thing that I see is a track cover from slide eeze (which actually looks like what we have in the groove). However, slide eeze's "track cover" appears to be something that goes over an existing track. If I replace our track with the cover only, I think that it may just fold over again. Maybe the old owners pulled out the real track and replaced it with a "track cover". I am totally confused. Any suggestions?

OK, fixed mine
