I went with these also. Will be installing them in a week or so. They really look like they designed them to last forever. The seal system is like nothing I've ever seen before. I haven't pulled a cap off yet because they are on so tight.

 

I had to have the drivers side replaced yesterday at 80k miles. Sorry don't have the tools/skills to do it myself, so had to have the dealer do it.

they put in a greaseable, PN ends in "464" so I assume it is the NAPA model.

They did the rear joint in my drive shaft a year or so ago and also put in a greaseable joint there as well.

Nice to have the ability to lubricate them... The engineer that thought non-greaseable suspension components was a good idea, should be beaten....

Not necessarily although some might disagree. It was brought up before. Greaseable u-joints aren't what they seem in the light truck world. I think the components used in big machinery are well designed and are made to get the grease into the joints properly. I don't think this applies to these small cheaper greaseables. Some have shown that even with greaseables you can still have joints that say only three caps get the grease while the fourth gets starved for whatever reason. On top of that, you are always thinking about when you're gonna grease them next.

I put greaseable Precisions in my driveshaft last week. We'll see how they hold up. Top quality non greaseable in the fronts. The Spicer 5006813's have NO holes drilled whatsoever and have precisely filled bearing cups with triple seals. We'll see how they hold up.

Little bit of both. Who knows... right?

 

This happen on my rear driveshaft, two caps didn't get grease and the joint lasted about 15k, my axle joints went about 195k and failed within 1000 miles of each other, they were non-greasable and I have a 2nd gen.

 

I put the Precision greasables in about 70,000 miles ago and yesterday I was pulling my trailer home from a job (6,000 lbs) and I began feeling a vibration.... If these joints have failed (will check today) I'll go with the sealed joints.

 

I put the Neapco 3-0485 non greasables in my front axles when I installed the Dyntatrac kit.

 

Finally got the U-joints done a few months ago. Also replaced the hub bearing assemblies. Thanks to my friend Aaron who's got a lift and the right tools, it went without a hitch. He cut the old joints out with a radiac.
