    Anyone have a surefire cure for stopping a urethane bushing from squeaking. I have the 21mm sway bar on my beam, and it has the red urethane bushings. The hotter it gets here in Tucson, the more they squeak. I’ve tried WD-40, and graphite grease, but still squeak. I have some dry graphite I may try. Setting off on a road trip soon, and don’t want to go crazy in the first 100 miles. Any ideas? Post up!

    try anti-seize, we used to use it on race cars with poly or delrin bushings

    Its the urethanes in the beam on the torsion arm. That is why we stopped building beams with red urethane bushings. They all suck. I laugh at they guys bolting in narrowed beams with shitty urethane bushings. They will forever have problems. In the summer time when the asphalt is 160 degrees, it radiates up to the chassis and suspension parts. Swells the urethane and causes squeeks.

     

    Original phenolic bushings are probably the best, bronze/brass, or white delron plastic also work great…Pretty much requires a front end rebuild with custom machined bushings. pita

    They’re the bushings that came with the sway bar Franz. I have a bay beam with needle bearings well greased.

    Sounds like you have baywindow problems 🙂 Dry ball joints? I can’t say I have ever experienced the sway bar bushings making noise.

    Could be ball joints. The ones I got to rebuild the beam didn’t have zerk fittings. I pack grease up around the joint in the rubber cup though.

    I just put one of these HD sway bars on my bay window with the same bushings, and was wondering if this would happen.

    I was thinking of doing this if it becomes an issue:

    I have been using Amsoil synthetic water resistant grease for a while now on poly bushings.  It holds up well and keeps them quiet.  I know some say not to use oil based products on urethane, but I haven’t had an issue yet.
