Simple...looking for what you guys think the best quality, longest lasting u-joints are out there.

 

Easy. Spicer Life non-greasable joints. They seem to be the only ones that have good enough seals to keep all the moisture and crap out.

 

For what spot? front Axles or driveshafts?

 

Sipcer, they dont get any better...

 

Alrighty appreciate the info and im looking at replacing all of them.

 

I got grease-able U-joints 180,000 miles ago, and they are still in fine shape. I grease 'em at every oil change, just like the rest of the zerks.

 

Some folks don't like greaseable u-joints because the cross is hollow for the grease passages and theoretically weaker than a non-greaseable joint.
Not so sure about that myself, a couple of non-greaseable crosses I've looked at still had the grease passages, only thing missing was the zerk.

 

Haven't personally seen much problem with u-joints breaking under normal use, not that it doesn't happen under extreme use. The problem I have with greasable joints is that they inherently have weaker seals, because by design they need a way to let grease and pressure out as new grease is pumped in. To me, those seals are never as good at keeping gunk out. I've also found that pumping grease into the fitting doesn't guarantee that it makes it into all four of the caps.

 

I've learned to just watch and pump my grease gun until grease does come out of all 4 caps. It generally takes 5-6-7 strokes.

 

Every u-joint i ever failed was due to bearing cup failure not actually breaking of the body. greasable or not +1 on the spicer's they dont get much better than that.

 

+1 for the spicer- but I always go with the zerks so when I exit deep water I can hit em up with fresh molly greese and force the muck out, Iv got all mine done except the front axles (dont look forward to that) but when you do the front driveshaft cardan drill a hole for a zerk in the middle of the shaft so you can greese that cardan ball- mine was all dry and full of sand from the previous owner- it took my friends log splitter to get those old 1995 cardan joint caps off btw- not sure if im allowed to post this or not, its a ford but almost the exact same doubble cardan joint and it helped me out alot!
