Need waterproof grease for splines.

[Fordiesel69]

Looking for the best possible grease for CV shaft splines.

On Dodge Ram 1500's, the passenger side stub shaft is male splined. The CV axle is female splined with a rather poor dust / grease seal and within a very short time frame the splines basically wash out and loose their grease. I am going to tear apart both spindles, and pull both CV shafts, wire brush and clean the splines, then re-apply hopefully somthing completely permanent until the boots rip.

Any suggestions?

Marine grease?

Most any Schaeffers moly Aluminum Complex Base will do great here. Check and see if you have a local retailer.

This is what ford specs for driveshaft splines.

Splines require a high moly content grease. I believe around a 5% value.

schaeffers does have some of the best greases on the market i would use the 274 or the 238 is also good. will resist water wash out a bit better than lithium complex in your case.

Is this a dynamic joint or would anti seize be appropriate?

This is the correct answer for splines (to prevent/minimize spline wear), specifically. I use Honda Moly 60. A little bit goes a long way.

Those are static splines on the CV and the small shaft, nickel anti seize is well suited for this application. On the spines that go into the diff use diff fluid.

PARAGON 3000 FROM TEXAS REFINERY. The water washout numbers on it are excellent.

They have lots of very good products and a great reputation for quality. Expensive and must be shipped though , unless one lives close to their facilities.

you can check at a industrial supply places or farm implement type store/dealers, or even check with a sales rep on bitog,if you need a tube of grease ,they maybe can hook you up with some.

For splines you need water washout resistance, load-carrying (EP) and fretting protection. A lot of people use various anti-seize compounds, others use grease with 3-5% moly. I would consider a calcium sulfonate complex with 5% moly. I would look for Cat Extreme Application Grease. It's CaSX, 5% moly and an ISO VG 150 base oil.

Why do you need EP and protection from fretting on a static shaft? That short shaft is so they can use a cv joint with internal inter splines instead of one with external splines that go directly into the transmission, diff, it has a snap ring on both ends of the short shaft to lock it in.
Subaru used to use these but held the CV inner joint on the short shaft with a roll pin, there is no movement that requires an EP lubricant like that of a moving spine. For moving splines Krytox has a lot of advantages over moly.

There are Dodge Ram 1500 repair videos that show the stub shaft splines with significant wear and what appears to be fretting corrosion. Even the snap rings can show significant wear. There does seem to be load and vibration to cause wear in some cases. Which Krytox product has advantages over moly? Several of the Krytox products contain forever chemical which are slowly be phased out.

I don't know the part # but Ford used it in their Ford 9L3Z4W602A kit for slide bump issues on some trucks. There is Krytox GPL-17 if you want moly in it.

If you are looking for a reasonably priced water resistant grease, it’s hard to beat tractor supply’s travelers marine grease.

I was just looking at this yesterday while there. They don't even specify what base it uses.... "trade secret."

One of the many reasons my dodge is a 2wd.
