Perm-lube bronze bearing

"Permanently" lubed bronze shoulder bearings in a knuckle structure. A pivot axle is bolted through the bushings and the spindle rotates around the bushings. There is play between the axle and the frame, the axle and the bushings, and between the bushings and the spindle. Pivoting parts are accessed by dust and grit. Maintenance involves replacement of bushings when wear causes excessive rattling between the bushings and associated rotating parts. Play between the axle and the frame can be reduced temporarily with a hardening compound.
