Sliding Doors Piaggio Porter 2007

I just had the rear hinge replaced on one of my piaggio porter's sliding doors as the roller had broken off. However the door still won't fit flush, and rattles when I'm driving. Does anyone have any ideas of what I should look into next, or how to realign the door so it closes as it should?

Thanks!

The rollers are actually very commonly available bearings - I can go search in my stash for the number if you want.

Adjustment will be simple, but trial and error. Does it close fully if you hip-bump the trailing edge?

Though if you paid for the hinge replacement, isn't it their job to finish the job properly? Or did it not sit flush before?
