replacing rollers and guides on PGT patio glass doors

Question

I have tried before to remove doors w/o success but now I was able to take them off tracks. No real visible way to reach rollers on these aluminum Patio glass doors,.

Problem is the door is dragging on the tracks. I have cleaned the tracks in the past and lubricated them with aluminum lubricant, but problem continues. I picked up two rollers at Home Depot, but Im doubting their sincerity they are for PGT doors as stated.
How do I identify and then replace the rollers and guides, please.

Thanks for posting! I'm sorry to hear that you're having trouble. The problem definitely sounds like the rollers, and you will have to remove them in order to identify what you have.

Lay door on some wood horses and remove the the two bottom door frame screws. Then, with the screws removed, take a block of wood and a hammer and lightly knock off the bottom rail. That should allow you to get to the rollers.
