Door hinges - grease?

[JLJS74]

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?

Normal. There are plastic bushings in the hinges. You can upgrade to Derlin bushings when/if stock ones ever wear out.

Don’t grease plastic.

That’s good to know...I was going to grease the hinges. Glad read this first.

Just googled "safe grease for plastic". Yikes, seems that there's an entire industry for this. Too much to think about. White grease seems to be the best answer:

"All-purpose white lubricant is designed to reduce friction between load bearing metal-to-metal and metal-to-plastic applications"

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!

I don't know anyone who bolts those bolts back in.

Let me introduce myself.

Why do I do it? Because I’m anal.

I used to be anal, owning a 2004 LJ and 2018 JL and off roading them cured me of that REAL quick.

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.

Splooge a little of this on there...

Just replaced my hinge bushings with the delrin plastic ones. The stock bushings are metal, they are swaged on both ends so you have to tap the edges in with a flat head screwdriver before you can drive them out

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?

Because you said "splooge," I'd expect to find this at a Lion's Den, and not Napa.

OK, I don't get it?
