You don't want those bushings to rotate or slide in the trail arm bore. I have always used KY as it is a water based lube that will dry out. I believe a little corrosion is desirable as it helps to bind the rubber to the bore. Silicon lubes remain and allow the bushings to move and rotate. I have seen several instances where the bushing has slid so far that the arm is metal to metal on the sub-frame and that makes for a noisy ride!
