New oem U joints don’t have grease zerks

Dealership said I got the correct u joint spiders for my 06 4WD drive shaft but they don’t have zerks like the originals that came with it. It this correct? Thanks.

 

Yes, all modern Toyota part # for u joints are sealed. They are better so far in my eyes.

 

Thank you.

 

I prefer sealed units myself. I replaced my oems with Spicer sealed units at 100K’ish.

 

Why?

 

I havent replaced a non-zerk one yet, the greaseable ones that all failed had dry spots on the end caps with wear.

 

Do you add more grease inside the cap than comes with it ?

 

Do you add more grease inside the cap than comes with it ? For OEM replacements?

 

No never. They are pre lubed.

 

My Prerunner shaft don’t have zerks. 134K on original joints.

 

I’ve got 258K on two of my original 3 I’m replacing the carrier bearing so doing all u joints too the old ones still have no play in them.

 

Not the Spicers I got, they had plenty lube in them.

 

Sealed units are arguably strong as well, no holes drilled for the grease delivery
