Sliding Glass Door Rollers

I bought this door 20 years ago at Home Depot. It has become very difficult to open and close. I've cleaned and lubricated the rollers to no avail. I would like to replace them. Please help me identify the correct parts.

It's hard to tell from this angle. Could you show us a picture of the roller removed from the door? Can you also tell me the dimensions of the housing? Specifically, I'd like to know its height and width. Please also tell me the diameter of the wheel. Thanks!

If by housing you mean the spot in the door where the roller assembly goes, it's 3/4" x 4 1/2 ". I've attached some better photos and I took some measurements. The roller assembly is 3 1/8 " long, 5/8" (maybe 11/16") wide, 1" (maybe 1 1/16 ") high, and the wheels are 1 1/8" in diameter.

It appears like you have two different style rollers. Can you confirm? Either way, see our 81-157 and 81-158. These look the closest to what you have.

81-158 is the better choice. The cutout at the top is there to make space for the weld in the corner of the vinyl. The 81-157 would probably work fine, but may sit unevenly on a large weld.
