Hey Half Moon!
How often do you grease those zirks?
I'm in the Suspension Biz, so that depends on how much you drive. If a car is driven a lot, then every 3 or 4 months. If gets driven only occasionally, then 8-12 Months or until you hear a squeek. Good rule is shoot some grease when you change the Oil
This is Important! Use only a Full Synthetic Grease for Poly Bushings - Amsoil & Mobil1 seem to be the best. A Petrolium Based Grease will soften Poly and cause the bushing to deform & fail.
Don'y believe the Hype that the Graphite in Poly-Graphite lubricates. Poly-G is a scheme to get more money out of your wallet. It's the same as a Poly Bushing with waste graphite strands. What is important in Poly is the Durameter reading.
