Squeaky front bushings??
I had done some work on my 82 which required the front end to be off the ground and stayed that way for two weeks. Well the other day I finished my project and today I drove it. Now I have a terrible "A" arm bushing squeak. What is the best way to silence it, silicone??

While poly does a pretty good job of reducing undesirable compliance when used in appropriate locations (yes, there are a couple of inappropriate ones), squeeking poly is binding poly. So, unfortunately, periodic lubrication is required. If not a poly bushing manufacturer's house brand of "snot", use a marine grade or other grease highly resistant to wash out.

Be aware that installing poly bushings on a sway bar REDUCES the anti-roll characteristics. The stock bushings are deliberately made oversize so that they grip the bar firmly when installed and resist torsional deflection.

The whole point of poly bushings is to virtually eliminate deflection of compliant bushings from entering into the suspension dynamics equation in the first place. And, stiction really isn't a desirable quality.

What about the bushings at the outer ends? Rubber there as well i guess?
On C2-C3 Corvettes where is the worst place on the front and rear suspension to use poly bushings? Thinking of squeaking noise

poster #14 showed the best way to do them, I drilled mine an installed the zerks during install but you can also do it after . you could also get a needle nose tip for your grease gun and do it that way also
