marine grease for universal joints

Hi
The owners manual says to use lithium nlgi2 grease for the universal joints and Lithium nlgi2 with moly for the yoke slides.

in a roundabout way it says that the moly grease should not be used for the universal joints.

Do you see a problem with me using marine lithium nlgi2 grease on the universal joints as I already have a gun loaded with this grease?

Also if there are balljoints and tierod ends with grease nipples then which grease should I use for these, moly or no moly?

I use marine grease for the uni bearing, as long as the nlgi class and the base lubricant is the same you wont have any problems with incompatibility.
Moly grease has very small solid particles mixed in with the grease and is designed for sliding applications only, i.e. yoke slide, rod ends, etc.
If you use moly grease in a normal bearing the small particles will get wedged under the balls or rollers and cause them to slide instead of rolling, basically fail early.

Thanks for the info. I have heard a lot about not using moly in unijoints but the first time someone has explained why. Appreciated
