thanks - clearest explanation/HOW-TO I've seen so far, IMO.... Doing this on my 14 LE, it has never been done even @ dealer when they did oil changes and included interval services.

With old oil (motor, diff, TC) it's always "out with the old, in with the new". However, with drive shaft grease, does the age and wear of the grease not matter? Is the only important factor whether or not there's simply enough grease?
Spicer, as well as most ujoint manufacturers, recommend greasing the ujoint until NEW grease starts to purge out of all 4 caps. While this creates alot of cleanup, having to wipe all the old grease off, it guarantees the ujoint is filled with new grease.

On the u-joints I always go to where there is fresh grease coming out at all 4 seals, then clean up the excess. On the u-joint spider bearing essentially all the grease in the bearing is being "used" (heated up and degrading over time) so I think it all needs to come out, and it's what the bearing manufactures recommend.
The slip yokes to me are a bit different there as there is "reserve grease" that is really not all being "used" when the prop shaft spins, only the grease where there is movement at the splines is being heated up and degraded significantly, and as grease slings out the seal new grease is pushed into the area to replace it. Of course if you never grease then there won't be enough grease to move into the spline area and provide lubrication. But I don't see a need to purge all the grease out of the slip yoke ever. I sent you a PM.

Motion Seconded!
Great tool! Just finished mine this afternoon using the LockNLube. It CAN be a little fiddly to get on to the zerk at certain angles, but once it's on, no issues at all.
FWIW - I am using Valvoline NGLI 2 rated, fully synthetic MOLY lube. Mine is 16350 miles old, and all 6 zerk points were essentially dry, what little bit that did push out of the spiders looked like dirty petroleum jelly...?

Awesome thread.
As someone who didn’t grow up around doing a lot of DIY maintenance on vehicles all of these maintenance threads are so helpful for me.
Recently got a 2020 TRD Off road and looking forward to learning as much as I can and doing as much work myself as I can to try and make sure the job gets done right.
Slowly making a list of all the tools and equipment I’ll need.

The grease I pump in is red, so it's easy to see a color change from dark gray to red when old grease is pushed out and replaced with fresh. I grease at 10,000 mile intervals or once a year.

Nice! I have learned a lot from this forum. I started just like you. It's pretty damn satisfying to do your own work. Keep at it.

Other lube points
Hi Guys, So much good info on this subject.
Is there any other zerk fittings besides the 6 on the drive shaft that we should be lubing while we are under there?
Thanks

It was a mistake on my part to start something in the other prop grease thread :laugh:
