About 2 years or 3k miles ago, I replaced my front drive shaft U-joints with Moog u-joints. The front one at the Dana 30 yoke was shuddering and vibrating at 60mph and higher (in 2wd). The needle bearings were crumbling, plent of grease. Oh well. What is the correct Spicer part number for the the ones with no grease fitting? Thanks. Art @003 Sport dana 30
 
Thank you. As I am in the middle east where local inventory is often Chicom knock-offs or nonexistent, I try to keep my own inventory of TJ parts for me and a couple friends. My cupboard is bare when it came to driveshaft u-joints. I will order extras. I did install a locally bought joint that fit perfectly, but it is not to be trusted. It read "Made in Japan", but for all I know it was a back alley piece of junk. It only has to last a few weeks.

You want 5-1310x

1001 percent sure.

I am *very* "old skool". Please edumacate me as to why I wouldn't want U-joints with grease fittings...
 
BTW, the very front DS u-joint set off a vibration and harmonic through the entire Jeep, while driving in 2wd. Vibration was in my arse and feet, but not in the steering wheel.

they are believed to be weaker due to the grease channel going through them, though there's an argument on Tom Wood's site suggesting that the loss in strength is not significant. They also require regular greasing, which most people don't do. The non-greasable ones commonly last 100k miles.

For someone who's regularly submerging their u-joints in mud, that would be a good application for greasable u-joints so they can flush the junk out.

It depends on the u-joint design whether greasable is weaker or not. If the zerk fitting is in the trunnion (body) it is weaker due to the grease channels that must run through the body. If the zerk fittings are on the bearing caps the strength is the same.

But durability can be way different like in the case of Spicer's 1310 size sealed 5-1310x and 1310 size greasable 5-153x. Spicer's sealed u-joints are crazy-durable and long lived, Spicer even says it's the best u-joint design they have ever made.

This shows the significant longevity difference between the 5-1310x and others, the second red one is the greasable 5-153x.
