U-Joints ?!? Greasable Or Non?!?

in the world of auto mechanics people have all kinds of opinions. what's yours? Do you like grease able ujoint or non-greasable?

[@jimb4715]

Spicer for sure, greaseable if you're going to grease them. Most people don't

[@906rootedoffroad]

I run non-greasable in my trail rig. I still run on road too but probably only put 5000 or less miles a year on it. I want the strength baby!

[@acaiblu1511]

I personally want feasible. Which is greasable. Sadly factory is usually sealed.

[@Okie93]

I would think greasable would be technically better. If you get into water or wet mud, just squirt some more grease in them to push any water out of the joint.

[@anthonyr5869]

Your going to break a lot of stuff before you ever break a greaseable u-joint.

[@OPMDS1]

Exactly

[@aboutmyfathersbusiness8324]

Maintaining my rigs, always under the vehicle inspecting and see those ungreaseable u joints. I just keep wiggling them every pm until I feel play. Peace of mind if they were greaseable.

Non greaseable Spicers. But axle shaft greasable since they're RCVs.

[@saintsmc1]

I always use non greasable. Stronger and 3 seals I stead of 1. That's why they last so long.

Thanks for the input

I'm just glad the tj didn't go off roading with those worn out u joints. Definitely would have broken an axle if you didn't say anything.

Hi there nice info! I'm searching for u-joint, as in driveline, comparisons. Do you know anyone who has compared wear, load abilities, and resistance to operational grime with OEM new u-joints and a few popular aftermarket brands too? Like Moog to Spicer to Toyota to GM, etc. I am especially interested in tests between the same size of competitive brands of both sealed and re-greaseable universal joints. Thanks!

@@discover4x4 yes. He doesn't have one yet. Surprising!

[@paulraschke1670]

Lol old school Grease able

[@discover4x4]

I thought my old way of thinking, Non Greasable was the old school. 🤣

[@matthewzombies1458]

physics says pass through should be stronger just like a hollow pipe is stronger then one not hollow

[@alexkram]

physics absolutely does not say that. What would crush easier, an empty coke can or one that was made from solid aluminum?
