Trying to remove door, managed to disengage door slider block from track, also top roller, question is how far do you need to swing the door out to disengage the bottom roller, have got about 30 degrees from the body but it doesn't seem to want to come out, can't swing the door any further because of the ladders stored in the garage, looks like I will have to shift the ladders, just keen to know how far the door needs to swing out.
If you've got it disengaged from the rear track, should swing out and let you disengage the front rollers. Might need 45* - a bit more than you've got. Taking it off is pretty straightforward.
