I wonder if the old style carrier-bearing that is greasable is available to fit our trucks ??
The guy up the road that has a bunch of tri-axle milk trucks uses a hypodermic shot-needle in COW size to force new grease into sealed carrier-bearings; if he can't get it in there any other way, he will drill a tiny hole, squirt in the grease, and cap the hole with a blob of stick-epoxy.
