Just installed greasable shackles and Daystar Poly Bushings on all for corners of my 1979 Dodge W300 Crew Cab project.
My question is: In your humble opinions, what would be the best lube to use, and how often should I lube them?
Thanks, Maddog

I believe Daystar sells a kit with a little grease gun and a tube of grease specifically for lubing their poly bushings.
