So you are saying that it would be better to run them dry? That is a novel idea that isn't often mentioned. On the other hand it may be sensible too as I recall I didn't grease them upon initial installation and everything was quiet.

The last two outings it was squeaky as all get out. As I was going to try to address the issue this week I got out the pressure washer, laid on my back under the Jeep and blasted the dickens out of all the links and bushings. The washer is a good sized 9hp bugger and puts out 3400 psi. After I was done the squeaks were gone! Was water acting as a lubricant or did I flush out dirt that was causing it? I don't know. Cleaning and over-tightening is certainly worth a try and costs next to nothing. Do you run yours dry?

I just did another google search and found Super Lube Synthetic Multi Purpose grease repeatedly recommended on various car forums for use lubing polyurethane bushings. The universal recommendation is that the lube has to be 100% synthetic and this seems to be the most frequently recommended. I didn't know there were so many people swapping out suspension components on cars. I knew Jeepers did it all the time but a lot of the performance car guys do too.

The mfg's website is: super-lube.com/synthetic-multipurpose-grease-ez-49.htm and they sell it for about 14.00 a cartridge

Some enthusiast web sites are selling it for 15-17.00 per tube but Ace Hardware can order it in (#8138323 is Aces number - the mfg product number is 41150 for a cartridge and 41160 for a can) for 9.95 a cartridge. My order will be in on Monday. The dealer is installing a new Rubi Locker under warranty Tues and Wed so when I get it back I'll disassemble the links, give them a good cleaning, slather them in this stuff and give it a try and see how it pans out. I hope it eliminates the squeaks. Either way I'll post the results.

I've always had great luck with Lucan Red 'n Tacky, and it did prevent any squeaks in my Full Traction bushings, but it didn't prevent the two rear lower control arm bushings from cracking.
I would be very interested in what and how to replace them with OEM style rubber bushings like out friend down under did.

I was told by Steve at Full traction during the Moab Jeeper Jambore to use a marine grease so it will not wash out. I figured he would know best.

Not all the Marine greases are 100% synthetic (I know - I visited two boat shops today). The poly doesn't do well with petroleum based greases and the lithium complex don't seem to persist. The Super Lube I mentioned above is synthetic and I think I've determined that the NEO that Redneck Jeep mentioned is. I have two cartridges of Super Lube coming next Monday. I was really surprised at how highly recomended the SupeLube was on the F-body (Camaro), Mustang, MiniCooper and other forums. It was like duh, isn't this what everybody uses. I even found some purveyors of poly bushings selling it and race care builders saying it was the only chassis lube they used. I'll know in a couple of weeks if it really works.

Default would be nice if the manufacturers would recommend what to use on their product!!!

Teraflex uses red poly and Currie uses black (poly???) bushings.

i called Currie and the guy said do NOT to use synthetic grease, and was supposed to email me once he found out a good grease to use. Never received an email.

I think teraflex uses a red lube (when new that's what was around the fitting) but don't know what it is?

I've been using Lucas synthetic, marine lube, anything that looked or sounds heavy duty = all over the map. figure any lube is better than no lube, but i know nothing about lube!
