I just set of bigger sway bars on my Firebird with the Polyurethane bushings, but now they squeak. Bad enough I cant hear it pretty well in side the car while driving. Is there a type of lube your supposed to use with these bushings? Any recommendations?

do they have a grease fitting ? If so, standard grease from a grease gun, pump it full till it comes out the sides, wipe off the overflow. If not, remove it, use a standard grease, wipe down the ends of the bushings, use a similar sized washer as a spacer over the greased area, reinstall.

No they dont have grease fittings. I will do as you suggested and see how it goes, I think it ought to do the trick.

Polyurethane bushing manufacturers advise to never use a petroleum based grease for poly bushing lubrication. Polyurethane should only be lubricated with one specific type of grease to insure a long bushing life, and squeak-free performance. Silicone based synthetic water-proof grease, the white sticky stuff!

If they are running poly bushings I hope thats what they are using. Although I have read many times where people have used just any grease they could find on the poly bushings and found out the hard way its not good on them.

Alright, white sticky grease it is then. Thanks for the input guys.

Well I looked all over and I couldn't find a Silicon based synthetic grease but so went with the closest match. I put on some pink synthetic grease made by Mobil 1 and that quieted everything right down. So its good to go for now.

^ good, glad that helped out. If I were you, sneak a peek at them every time you change your oil. I lube mine up about every 3-4 thousand miles and it seems to be a good interval for me.
