Proper Lube for 4x4 slip joint?

So i have seen vastly different opinions on lube for the slip joint on the rear driveshaft of the 4x4 2nd gen tacos. Im gonna be hitting 100k miles here soon an am going to go through the truck front to rear and get everything that isnt a normally scheduled lube item, this includes the rear (and front) slip joint on the driveshafts.

I have seen from standard grease, to moly specific fancy $$$ grease.

Whats yalls opinion?

Im leaning towards

$49 Loctite 234227 LOC51048 Moly Paste Anti-Seize Compound, 8 oz.

That's what I use. It has 65% moly- the typical moly fortified greases only have a few percent. It's enough to last a lifetime and more if you only use it for the splines. I primarily use it on puller screw threads.

Edit- here's mine with 110K miles- pretty dry. I took both clamps off, but you only need to remove the larger one. You can reuse them if you're careful- I did. I couldn't find any replacements locally but Napa said they can order them

 

I was just doing some research into this because my shaft clunks at the slip joint. It seems that Ford and GM use this Ford Motorcraft XG-8 grease to stop the clunk. Several here have recommended it too in other threads.

Splines and screw threads are extreme pressure interfaces- this is where moly excels because the moly particles are left behind to lubricate as the carrier agent is squeezed out. IIRC, Dana says NGLI 2 grease is ok, and anything is better than nothing. If you google it, you'll see that spline drive lubrication is a big issue on motorcycles and high percentage moly, >60%, is what the manufacturer's recommend.

 

Looking to try it for my slip yoke.

 

The factory stuff is black and extremely thick IIRC, never been able to find it but the stuff you linked should be fine IMHO

 

Awesome! thanks guys! I figured a super high moly content would be ideal for such a situation, I have used similar on input / output splines on shaft driven motorcycles like mentioned just wanted to make sure it was OK with the coating thats already on the slip joint.

 

Just following up on this thread. I need to lube my slip yoke. What has worked best and lasted the longest? Ford or Loctite Moly Paste?

 

I used the ford ptfe blue stuff about 10k miles ago and still working the same as the day i applied it. It was like 10-15 bucks on Amazon and im sure the tube will last me the lifetime of the truck if i ever need to reapply.

 

Great to hear. Ford looks like the go-to product. Thanks for the quick reply.

 

The Land Cruiser community has a lengthy dissertation about slip yokes and grease. It always makes for some interesting reading. I do learn a lot from reading the posts.

I used Honda M77 assembly paste on the slip yoke in my 4runner. Most definitely cured the clunk
