So I received a rear sway bar from my gf as a valentine's day present!! One of my friends told me about wrapping your sway bar with Teflon tape under the bushings to stop squeaking. A quick Google search showed this being pretty popular. Has anyone tried this on their fiero? Anyone with a rear sway bar notice much squeaking from there sway bar bushings? Is it worth it or is the lithium grease sufficient?

I guess you have poly bushings. I never tried Teflon tape but I can see how it would work

If the grease isn't sufficient, then you probably didn't use enough.

I haven't installed the swaybar yet. I was just intrigued by the information and wanted to see if anyone had any input or cons?

Con would be that the bushing is a moving part with pretty tight tolerances.

If you want to use teflon at all, I'd suggest a spray-on product would be better than tape.

I assume you're talking about the center bushings, not the end links. I prefer to use heavy grease. The thicker the grease, the longer it will last before needing to be regreased.

I replaced the front and added a rear from a TFS kit over the Christmas holiday. We used the supplied lubricant and I've not noticed any noise.

I did, however, completely fail to figure out how the weird captive nut plate for the rear swaybar could possible work on my 87 GT. After fussing with them for a while, and even stewing on it over lunch, we gave up and cut the nuts off the curved plate; it just didn't fit inside or outside the frame rail.
