starfire - I've never seen an original 50's Ujoint that didn't have a zerk, might have changed later
Denny - the same "controversy" can be found on vintage Brit sites re heavy oil [factory recommended] vs grease [common] for some front suspension points .... I've also noticed the shop manual recommends the same lube for the Ujoints as is used in the trans, but been using grease on them since the dawn of time and have never seen [or even heard of] anyone who did use the gear oil, although one way I've used to clear plugs is to remove the zerk, squirt some penetrating oil in the hole, replace the zerk and hold pressure on it with a grease gun for awhile - pete and repeat
