Polyurethane Bushings
I Was Just Wondering What To Do About Squeeky Polyurethane Bushings, I Used The Supplied Grease And Used It Religiously But The Bushings Are Now Making Quite A Bit Of Noise After A Couple Months Of Use.

Best idea, switch to solid in the control arms and use greasable in other areas.

Do you still believe in all the things that you stood by before? Are you out there on the front lines, or at home keeping score?
Do you care to be the layer of the bricks that seal your fate? Would you rather be the architect of what we might create?

poly has no place in a pivot application that can not be greased regularly

Which bushings are noisy?

I second the synthetic grease. I hate Poly control arm bushings! By the way I got some greasable sway bay bushings, and all it said was use your favorite grease, no mention that it had to be synthetic. I know polymers and would believe that petrolium based grease may damage the bushings

Somehow I didn't get grease with the bushings (or not enough, can't remember) and used copper grease.....never had problems with noisy poly bushings....
