Grease zerk on drive shaft

[ChevroletTough]

Hey guys, was under my K3500 just looking stuff over. Found a grease zerk on my front drive shaft (from transfer case). I’ve never see one on a shaft like that. I cleaned it up, and greased it. And put a cap on it like i do with all zerks. Took quite a bit, 9-10 pumps.

 

Is that a common zerk spot for 1 tons?

maybe post a pic of the zerk location.  If it's on the u-joint, that wouldn't be unusual, or possibly if it's near the sliding yoke, you might be pumping gear into the sliding area...

I’m guessing the sliding area. I’ll have to snap a pic. Not on the yolk.

My 84 K-20 HD had one too, so it's not exclusive to 1 tons. My guess is that it's more common on front straight axles rather than IFS 4WD because of the suspension and front drive-line travel.

My truck has front cv axels

It's for the slip yoke joint

Yeah kind of appears that way to me too. Thanks.

I was under it again lastnight, yup slip yolk shaft.

4wd trucks have a zerk for the slip joint on the front driveshaft, regardless of brand or if it's a 1/2t up to whatever.  I'm sure there is an exception or two somewhere in the world.  And yes, it's a great idea to keep it greased.......
