hi everyone, just picked up my first used 3dr frontera sport 4x4 sport,

i have noticed that the rear door has droped is this a common problem, and is it easy to fix, ? it looks to me as if the weight of the spare wheel is pulling on the hinges?? it doesnt look like im able to open door without it dropping,and when it does its hard to reclose,i guess i should keep wheel in side. any thoughts please. ps. also new to 4x4 any adivce with theses little beauties...

also any off road places i can test it out near( south birmingham) nothing taxing mind as i wouldnt want to get it to dirty
