I'm thinking about just the opposite.
I will be removing the doors in a few hours, and since I'm used to my JK style doors, the limiters are not a requirement. It would be nice if I could find a tighter fitting hinge bushing so the doors didn't swing so easily.... No need for this new limiter hardware if the doors didn't flop around. Maybe?
Not thinking a tight hinge is a good idea, plus it would eventually wear out and be "loose".
My LJ doors fling open with the greatest of ease. I actually bought shorter straps so I don't fling open and hit cars next to me.

Greasing an exposed joint like the door hinges will cause dust and dirt accumulation in the hinge, which may then lead to premature failure. The bushing is a wear part and replaceable for a reason.
Just noticed in my owner's manual that for regular maintenance, it's says to grease the door hinges twice a year with white lithium grease.

Bought some WD-40 Specialist white lithium grease spray just for this reason. Do you think it's still unnecessary and should I be removing the hinge pins/bolts to do this or just spray some at the joint and wipe any excess off?

Lift the door and lube the bolt and bushing.

Thanks! Eventually found a video recommending exactly that. Spraying lithium grease likely won't migrate very well without cleaning and applying the grease directly.

Just curious, but do you still not personally recommend lubing them because of the plastic bushing or not really a big deal either way?

Took the doors off my JLUR this past weekend, was pleasantly surprised with how easy the process was and obviously how fun it is to drive without them. Before I put them back on (supposed to rain here all week), I noticed that the inside of the hinge that’s part of the car frame seemed dry - I was expecting it to have a thick grease inside. So my question, should I add grease before putting the doors back or is that how its supposed to be?
Yes buddy, a tiny dab of white lube and your doors will slip right out every time.

Personally I use white lithium on my Chevy but not on the Jeep, I see too many gravel roads. Most people, street drivers, won’t have any problems with adding a little grease as long as it’s not excessive. I would lube the door check strap if anything.

Thought you were being funny and telling me to lube up the nylon strap, but eventually realized you were talking about the metal check strap that people always get stuck inside the door ?

I'm on gravel every day, but never going fast enough to kick up much dust. I get a lot of dust from road salt during the winter more than anything else, so I'm really not sure if a little grease would help protect against that or just stick to the grease and accelerate corrosion.

I honestly have no desire to take my doors off for any other reason, so maybe I'll just leave it alone for now, as long as it's still opening smoothly and isn't squeaking or anything.

Sorry, I’m not a funny guy. The actual check strap, detent, whatever they want to call it, has rollers and is greased from the factory, so it seems prudent to maintain that.

Retired from Corrections....I have stories.
Just throw a dab of anti-seize on the bolt threads before putting them back in.

That way they come out next time.

And of course you'll have some on your elbow, the dog's tail, and the upstairs bathroom... Because as soon as you open that stuff, it gets everywhere!
This is what I do.
