Grease fittings! The problem with the sealed ones is, well, they are sealed. So the only way to service them is to remove them from the shaft and take them apart to grease them which let's face it, nobody is going to bother to do. So the little shirt they come with will eventually turn to dust and the joint will let go.

No problem. I learned that the hard way. Had two sealed driveshaft joints completely dry out. One shattered and nothing but powder came out. Replaced the rest and when I pulled the caps I found the same powder left in each.

The spl series sealed joints will go atleast 80k, and never need any looking after them every few weeks, greasable joints need to be greased, or they'll last less.

I use the spl series in my truck, cars, jeep, my jeep has 135k on them and they're still going.

The ones that don't get those miles out of them are the people that don't know how to install them correctly.
