You should be able to lift the door upward and move it out from the track frame. You can then look at the rollers to determine how to change them.
a very comprehensive answer so only three points it does say they are heavy, they certainly are if they are of any size, definately 2 or more people required. find out who the maker is or failing that the installer and get spares beforehand in the uk at least they may have been fitted with an anti-lift device, to stop burglars lifting them out, its usually a metal or plastic plate which is stuck to the underside of the top track, sometimes top of door, when its closed, remove it if it stops it being lifted
mostly it would be apple juice or orange juice maybe even cranberry juice but mostly the best thing would be apple juice
Sliding Glass Door Rollers
You may also notice that they're adjustable (up down) usually via a screw on the side near the bottom.
