The bolt heads without grease fittings will have a nylon type bushing they don't require grease the ones with grease fittings will have a brass or bronze bushing they need a shot of grease every trip out over 2000 ks or so .. You can get all pins that have grease fittings if you want . The grease able pins are best if in fact they are actually greased. The nylon bushings are cheap that's why they are there . All these moving parts are subject to ware and over time will need replaced. The trick is to keep an eye on them and replace just the bushings before the pins ware through the springs and hangers . If the axels track side to side more than when new, while parking and cornering That's an early sign the bushings are worn.
