    I installed some aftermarket control arms a few years ago. Directions said "Grease your control arm bushings 2-3 times a year adding only 1 pump of grease, DO NOT OVER GREASE."
    I've had problems with noise greasing at that interval. How often do you lube your polyurethane?

    No matter how much I greased my rear sway bar, the squeaks returned. I stopped greasing them. Now they have some play, but make no noise anymore.

    Thanks, Juice. Part of my problem is the low quality grease fittings now-a-days. The car is noticeably quieter since a local shop installed some new fittings and pumped the bushings full of grease.

    What kind of grease are you using? I use silicone, not petroleum, grease on my poly bushings and have no squeaks.

    I'm using a marine grease. Maybe Lucas brand? Are you talking about silicone spray?

    Thanks, Laga. Ima have to try that. I had used the SuperLube teflon, but maybe I didn't use enough or often enough.

    In the heavy equipment world we usually grease joints weekly. Sometimes every 8 engine hours depending on the stress the joints are under.

    Thanks, Total. I've added it to my calendar for every other month. I'll see how that works.
