Our Pella slider seems to need new door rollers. The slider is likely 20-21 years old. We had someone look at the door which he removed and determined the wheel bearing was bad. Unfortunately I did not take a photo of the wheel while the door was off. I have attached a photo of the door in hopes that you can identify the roller we will need.

Hey Wendy. Pella doors tend to use either the 81-244 or 81-098 (We also carry a generic version of that second roller, our 81-249). There is unfortunately no way of narrowing down further which one you might need (if any of these) without seeing the original. Honestly, in most cases it's impossible to narrow down sliding glass door rollers at all without seeing the originals--in the case of Pella, we can at least make some educated guesses. You can always try either of these types, and then return the ones that do not work. See our Return Policy here. Let me know if you have further questions.
