I tried smearing the crap out of the bushings with dielectric grease (I was too afraid to try petroleum based stuff) but it'* only gotten louder. Does silicone spray have petroleum products in it by the way? The silicone spray can I have is called pyroil
) but the name suggests what it might contain. Anyway, I'm guessing the grease probably needs to get in between the bolt and bushings to make the noise stop and since it'* pretty thick I would probably need to just take it apart and lube up the inside of it all.
What would you think about wrapping teflon tape around the smooth part of the bolt. Grease would work but would eventually work its way out - same with silicone spray and the tape would always stay. Maybe even teflon tape with silicone grease over it? Any thoughts?
