My passenger door sticks really bad....my girlfriend can barely open the door...i have wd40'd it a few times just to make do for her, but now its time to really fix it...what kind of grease should i use to make it easy and last a long time?

 

i'd say you have a problem other than lack of lube on the door. is the roller working correctly in the hinge? is it damaged, it's very common. is the bushings wore out? they're fairly esy to replace. if it is just a matter of needing grease i'd use white grease on it.

Ill check for the other problems. I think it just needs to be lubed cause whenever i spray wd-40 on it it works just fine...the only problem is that the wd-40 doesnt last very long. If it is another problem would the WD-40 even help??
