Hi bunnings workshop,
I have a heavy metal gate that hasn't closed properly in years because the door is leaning
It is hard to see the extent of the leaning but I've taken a few photos to show the problem


Photos of top and bottom hinge (can't see much here)


Photo of side away from latch, top and bottom:



I'm happy to provide more photos but it's hard to photograph the lean (and spot it in person) but the scuff marks on the fence where the door is meant to close indicates that the door is leaning too much on the top side.
Was wondering how I could fix this? I'm not sure if I could get a jack under because of the stones, and tighten the hinges in some way?
Please let me know of any ideas or any further pics/info needed. Thanks!
