2006 s type r. A couple months ago i had to replace the radiator on my car. Did it about 7 years ago so i knew shortcuts. Old radiator cracked at the top inlet hose area and into the side tank. Kind of surprised me being a nissens. Anyway. This time i remembered to replace the sway bar bushings. Wow what a difference. No more bump in the night and solid feeling too. What i forgot was to lube the new bushings slightly. Last week i got the loud squeak on speedbump type bumps. I sprayed some silicone lube as best i could and it was resolved until today. Oh well. I am not going to remove the bushings to grease as they are buried beyond my desire to eliminate the squeak. Any suggestions on another lube to use. Otherwise i live with the squeak. It is a more than fair trade of squeak vs perfect ride now. I might be able to take the bottom plastic cover off that attaches to the bumper cover and get in close to the bushings. I have an oil leak to inspect that requires that cover to come off

 

Do not use petroleum based grease on suspension bushes.

I use Molykote DOW 111 Lubricant & Sealant, 5.3 oz. Tube
It is safe for rubber parts.

 

thanks bob. Unfortunately i will not get access to inner bush again i dont think. I might be able to loosen cap bolts and then remove link bolts for a little clearance to squeeze some in

 

Here's what I do now after fighting this in many different ways. Maybe too late for you since it's all put back together.

First wrap the bar where the rubber bushing goes with thick Teflon tape like whats used for sealing threads. This tape comes in different colors and different thickness's. There is a monster blue version out now that looks to be thicker than the old white stuff.
Then I use a silicon based lube as well. Just a belt and suspenders type arrangement. Some nice aftermarket bar brackets also have a grease zerk so you can lube them at regular intervals too. Of course all I have is a grease gun and as posted above petroleum based lubes should not be used on rubber compounds.

yeah club my bad for not addressing the problem before i put it all back together. Hindsight. Right. At least it is maybe doable via loosening the cap and using spray silicone
