Grease/Lube for Poly bushings
I've read and heard that poly bushings can squeak unless you grease them well. But I've also heard the grease doesn't stay put, and squeaking can start within a year of install. In the forum archives, I noticed some people using "marine grease" for the bushings.
My thought - We use this stuff called "extreme pressure lube #3" at my work for placing on dead centers. It provides lubricity even when the contact area is squeezing most of the lube out. I was wondering if this might work well... Any thoughts?



When I installed my VB&P polyurethane suspension bushings, they were packaged with "TefCone" lube, which is some kind of teflon/silicone compound.
Like Big Fish said, the key aspect is the chemical effects on the bushing material. Anything that would tend to harden the material over time would be bad.
Some of the aftermarket manufacturers are putting grease zerks on their bushing shells. Wish I had known about those before I replaced every single bushing in my suspension... :rolleyes:
