i have no idea how or when this happened but i was underneath the truck yesterday and noticed that my grease nipple on my ujoint has snapped off. is there a way to fix this aside from replacing the entire ujoint?

 

You can buy grease nipples, getting the broken bit out is the hard part.

 

By the way, they're called Zerk fittings.

 

usually an EZ-out is the best bet. however, i've gotten lucky and had zerks that got smacked and loosened up, and i could remove the broken piece with my fingers.

 

ok. what's the difference?

 

Zerk fitting is the technical name, but I just like saying the word 'nipple'
