Thanks! I rebuilt my front when I pulled my trans for tq swap.

I am curious of how many others ditched the non-grease able ones. I did as part store only had grease ones and I am under my truck once a week and grease my ball joints and steering components . And when I rebuild the front end am also replacing them. If anyone else has I would like to hear on results. I use amsoil full synthetic water resistant grease

I stuck with non-greasable ones since they seem to do a good job lasting if all is in order.

That is understandable but my background is of working on a 1,000 + truck fleet of ken worth t800 tractors and while I was a lube tech every truck got greased up. And for what it's worth the 100 of thousand miles the trucks go it seems like the grease able u joints hold up given they are greased often and done properly.

Look into NEAPCO joints, i like them better then spicers, they seem to have a better tolerance, feel heavier, and are made in Pittsburgh PA.

the only joint that lasts inna log truck is Spicers...Naepco's are junk in comparison..... I've changed hundreds of them.

I just did the rear driveline in my 1-ton and it got Spicers.

 

[FrankTheTank]

Really.... they seemed beffier to me, do the bearings go out faster? What went wrong with them to make u change them?

 

[Old OutLaw]

the Neapco joints are softer, far as I could tell, they just didn't last as long as the Spicers, the crosses would lose the hardfacing and start vibrating, I wouldn't use them personally.....

and I worked the Logging - Trucking Industry for 40 years, as a driver-owner-mechanic....

Good to know... i will stop recommending them then. If they were softer that would explain why they looked beefier and felt heavier. To compensate for the weaker metal
