i rebuilt the front end of my 68 with PST polygraphite everything about 3 months ago. I drive it almost everyday, and it sounds like the polygraphite bushings are starting to squeak when i hit bumps now. I was under the impression that these would not squeak because they were self lubricating. How can I stop the squeaking without having to lube the thing every couple months. thanks.

While I didn't use these I found that lubricating them with grease ( I used synthetic Valvoline grease ) was quick, easy and effective. I unbolted the sway bar bracket one side at a time with that side of the car jacked up. The bar dropped down enough to take out the bushing, coat the inside with grease and reinstall. It took me about 10-15 minutes per side and everything's been quiet since.

I have the same thing happening on my '69. I have been using a spray lube on the sway bar bushings to stop the squeek. It's good for about a month or so and then spray again.
I posted the same basic question and had it suggested that I get greasable sway bar bushings ($13.95 @ summit). They have zirk fittings in them.
I haven't ordered mine yet but quit lubing the bushings on the ends of the sway bar as the squeak is only coming from the 2 in the center of the bar.

I had the same problem on my 92', but the sqeeking went away when I put my Flowmaster on! http://www.camaros.net/forum/smile.gif
Honestly, I drilled and tapped my sway bar mounts and put grease fittings in them.

As others have noted it is probably the sway bar bushings making the noise. Did you put that "cheese" on that comes with the sway bar bushings? It is supposed to keep them quiet. The grease fitting models would for sure fix the problem I would think.

Never saw a poly bushing that didn't squeak, "polygraphite" or not; many fellow vintage Vette owners I know used poly bushings in control arms and sway bars during their restorations, and all of them now regret it. Even the grease fitting trick on the sway bar bushings doesn't work unless you pull the bushing out and drill a hole in it, through to the sway bar hole, that lines up with the grease fitting hole in the bracket. Only real fix is to rebuild again, with stock rubber bushings - no noise, no grease, no problems, and they'll last another 20 years.
