Universal Joint Splines -- To Grease or Not !!!

[Guest]

Not a GS question, but for my VX Project.

The universal joint which connects the drive shaft to the secondary gear output shaft has a female spline on either end as seen in the pics.

There is no mention in the workshop manual of lubricating these sliding joints.

Does it require to be lubricated and what grease is best to use, Moly60 or something else.






Thanks in Advance.

As a rule I put moly grease on splines so that the parts don't gall or otherwise stick together. I don't know if it's necessary, but it makes me feel more secure.

I always do too.
Why would you not?

I have never herd of a spline that wasn't supposed to be greased.

Well, you see, I'm not a shaftie type guy. I am a chain drive type person -- so hence the need for some advice. The shaft I removed from the universal originally had no evidence of grease or any other type of lubricant. The final drive I purchased from the U.S. which is in the pics attached shows some old grease at the bottom of the splines, but does not look like moly.
