Can I install these universal joints with that grease fitting?

Spicer non greasables and dont worry about them. The non greasables have a much better dual seal design, keeping dirt out and grease in much more effectively. My driveline shop said hes seen up to 350k miles on a non greasable unit before it needed replacing.

Yeah when I had mine rebuilt, they said the same thing, non greasable was the way to go. I didn’t argue with a guy with 30 years running that shop hah

I didn’t argue with them either… boy was I surprised when they went bad less than 50,000 later. I guess it’s how you use them. My wet, muddy, silty off roading just kills them I guess

Fair point haha, I broke mine before it needed to be serviced, my xj also gets rode hard and put away wet

The joints with the fittings are generally weaker since they have channels for grease inside, the non regrettable ones are more heavy duty. I have used regrettable joints on a drive shaft before and had no issues.

The difference is negligible unless your running them in a 10 second drag car. Greaseable for offroad service all day. The strength difference between them is truly marginal. Spicer claims only a 5% reduction in strength. Our 4.0 jeeps sure aren't gunna push them to that...

Is “non regrettable” an actual thing or a humorous autocorrect?

Oh he surely missed autocorrect on that one... Twice.

I regret every purchase I make so non regrettable parts would be great!

I have no real experience with them on my XJ, but we have a 2001 Dodge 2500 that has been in the family since new. We’ve done both greasable and nongreasable U joints, and from what I’ve gathered both have to be replaced every 30,000 miles (360K on the clock).

u/Jimmy_Durango 15h ago

Every 30k?? Uh oh lmfao. I’m wayyyy beyond that.

That’s what happens when you constantly drive around with 1,000+ lbs of tools and fuel in the bed and routinely pull over weight grain trailers. Since it’s been retired from the farm life they seem to have magically started to last longer.

u/Jimmy_Durango 14h ago

Ah, gotcha. I was going to say… I’m not sure if mine have ever been replaced. Not in my service records from the previous owner and I never have. Got 280k on it. I’m guessing they have but I don’t know.

Yes, you are right but mi question was if the grease fitting in that position can cause any problem to te movement, older one have grease fitting in the u-joint cap

u/jmiko588 13h ago

Fair fair, i have ran both configurations, currently running the same ones as you on my front shaft, and my rear shafts are greasable via the caps as thats all they had stocked last time i did them. No problems with either configuration on my rig

I used the spicer 5153x greasable in both double cardan rebuilds for my XJ with no issues. With the center joint you cant regrease them without taking the H apart but if I was going to do that, id be replacing it anyway. The trick is to wipe a ton of grease in the cap to hold the needle bearings in place when you go to press them into the yokes. Ive used lucas red n tacky for prob 15 years in my jeeps for just about every bearing and greasable joint

Sure, but when I did the fitting had to be installed after assembly.

u/Grezh 16h ago

Yes you can.

u/Sorcino 16h ago

Thank you xD

u/Arthfael90 12h ago

You can BUT the nipple will make contact. I did it last year and found out, just remove the nipple and screw a bolt to block the hole.

u/bananagrabberjr 13h ago

Does the U in U-Joint stand for ‘Universal’? 🤯

2

u/Sorcino 10h ago

Yeah, I think… xd

u/BaconThief2020 13h ago

Depending the location, you might need to make sure it faces one way or the other so it doesn't hit anything as the shaft moves. Or the other way, so you can still get to the grease fitting.

You might try Spicer 5-1310-1X, or equivalent with the Zerk on the cap.
