Urethane VS Rubber bushings
 

What are the pros and cons of the 2? I've heard that the rubber ones are great but don't last as long as the urethane. But I have also heard that the urethane bushing tend to give you a sqeaky ride.

I've heard guys fighting squeeking poly bushings forever and finally giving up and going back to rubber.

unless you need the stiffer bushings for a certain reason........go rubber

polygraphite is your answer.
no noise stiffer suspension

Rubber- works great, lasts along time, fairly cheap

Polyurethane- squeaky, cold flow properties result in control arm bushings taking set in oval shape leading to slop, no real improvement over fresh rubbers

Polygraphite- same cold flow issues as previously discussed with the added benefit of introducing a compound NOT compatible with urethane. The result is the graphite breaking down the urethane over time.

Teflon/Delrin/Nylon- eliminates all bushing compliance, lasts forever, not terribly expensive, impervious to the elements, no NVH issues.

Basically the Teflon option has zero drawbacks and lots of advantages.

Thanks guys! Damn I love this site:lateral: :bow:

Put -squeak- PST "Polygraphite" bushings -squeak- in the -squeak- old man's -squeak- BelAir -squeak- and had to -squeak- drill and -squeak- add zerk -squeak- fittings to stop them from squeaking. Will probably destroy the bushings eventually, but at least they no longer squeak!
