TR2/3/3A What do you do lubing polyurethane bushings?

I've never messed with poly before, and my research tells me to use something like super lube to assemble the bushings, then never grease again. I am thinking to remove my zerk fittings, replace with plugs to prevent them from being greased, esp with oil based grease.

What do you all with poly do?
 
I used super lube when I assembled because there aren't any zerk fittings on the bushings.
 
Teflon grease is what I use. and what I have gotten supplied with some of the poly bushings. It is a very sticky white paste. Usually in the plumbing section at big box and hardware stores.

Sounds like prothane super lube. I bought a tube that fits a caulking gun and have to wear gloves to keep it off my hands. I think I used WD40 on a rag to remove the excess. Extremely sticky.

Ok PO must have installed them?

They would have had to also drill out the bushings to get the lube to the pivot points. The tie rods and steering arms have lots of zerks though so probably that's what you saw. Anyway - lots of sticky lube.

The bushings from TRF have the holes already. these are on the lower control arms
 
You might find this interesting. It basically echos what I've been told before: the main thing is to use a water-resistant, sticky grease so it doesn't work/wash it's way out of the joint. Petroleum-based greases degrading the polyurethane is mostly a myth, passed around by the folks that want to sell you overpriced "urethane" grease.

The inner pivots didn't have grease zerks originally, but they're a worthwhile addition, IMO, even if you stick with the stock nylon bushings (on the lower ones). I added them to my car a long time ago. Not clear to me why you'd want to change to poly there, the original nylon is pretty hard and lasts a long time (longer with an occasional shot of grease to keep water out).
