some u joint talk

I have a little knock coming from my yolk, I believe its time to change out u joints, should I go with greasable ones or should I go with ones that are greasable? I don't think the yolk has a zerk fitting, at last One I can't find, any ideas or advice. I was told that the stock yolk does have a grease but I haven't found it yet.

All that would depend on how and where you drive your Wrangler. If you do a lot of off-roading that includes mud/water pits then a u-joint with a Zerk fitting might be a good investment. If most of your driving is dry then go for the standard joints.

By the way, you are planning to replace all of them, right? It just makes more sense to do it all at once, in my opinion.


But the wisdom that is from above is first pure, then peaceable, gentle, and easy to be intreated, full of mercy and good fruits, without partiality, and without hypocrisy. James 3:17 (KJV)

Go with sealed u-joints, they are more durable and stronger than those with a grease zerk in the trunion (body). The only time to go with a greasable u-joint is if your Jeep is a mudder and you need to regrease everything each time after doing deep soupy mud.

Your yokes (not "yolks") are not greasable.

Excellent u-joint choices include the Spicer 5-1310x for your driveshafts (non-Rubicon) and Spicer 5-760x for your front axle shafts.
When you have a choice, buy American.
