two piece drive shaft questions

I'll crawl under it and check it all out. If I wind up having to drop the carrier bearing to get the U-joints in phase, I'll take another look for the zerk fittings. I would expect to have more of them, maybe they're missing.

For the time being I want it to run well enough to get the cam broke in, then I'll take it in to get the carrier bearing pressed off & the new one on. It needs at least one new u-joint, so probably do them all while I'm at it.

Some U-joints don't have a zerk fitting but just a plug. Some don't even have a threaded hole to put one in.

I remember hearing a long time ago that the 'zerkless' U-joints were actually stronger because the grease hole weakens the spider. Course you can't lube it after it's installed.
