Found that the energy suspensions grease works wonders on the forward leaf spring mount bushings.

To me, those bushings seem to make the most ridiculous noises. In some cases sound like metal to metal and even vibrate the truck at times when binding. When lathered up real good with grease, noise still tends to come back in 2-4 months depending on use. I have done this about 4 times know. Makes a big difference, fairly quick and easy to do maintenance.
The SPC delrin bushings on the UCA make chirping noises like a bird. These don't bother me enough to want to take the UCA off and grease the sleeves inside the bushing. I would make a wager that if I used the energy suspension grease liberally inside the bushing where the sleeve goes I would never here much from them. Those are really nice bushings way tighter than the Alcan ones.
For the hiems (lower coilover mount / hiemed tie rods) I use Tri-Flo. I squirt them before I go on trips or just about everytime I stop to air down since its right there anyways. It helps. Might be a better solution that requires less attention though.
