So Im looking at replacing the universals in my front diff because they are making a bit of noise.
Anyway I was having a conversation about it with my dad about them and he tells me to go for the non greasable ones and just replace them as they start to make noise.

What do you guys think?

I just did mine with the "sealed" u joints after a good friend and excellent mechanic told me they were better.

Always go greasable

Always greaseable

Greasable ... if you service them regularly ( more frequent with harsh use ) they should last forever.

I never had to replace a greaseable u-joint.

OEM sealed ones suck because you know that at some point they will have to be replaced.

OEM sealed ones were developed to CUT COSTS by the manufacturers. They no longer had to lube anything on the line. Was a time when a lot of parts in the front end/steering were greasable. I think I remember greaseable ball joint and the like.

i only run greasable ones takes all of 30 mins to do all the joints and point in the jeep once a month cheep easy maintenance VS having to swap out u-joints

You can get some over spill and use it like carmex

The hole for the zerk fitting (If it's in a crotch and not the caps) weakens the torsional capability of the joint, so non-greasable joints will be stronger than the same size joint with a zerk.

For my drag car, I use non-greasable.

If you do a lot of mudding or it's basically a glorified daily driver, greasable is the way to go.
