I need to replace my CV axles on my 2008 Silverado 4wd. What is a good grease to use for the splines that go into the hub?

I have a can of the old GM grease (part # 12345718). Would that work or should I use something like a marine grease? I want use something that I can get at the local parts store.

I've only replaced a few CV axles. Never used any grease. The splines are locked into place with the tranny, unlike differential gears, which mesh and unmesh continuously.

Wouldn't grease from the inner spline contaminate the ATF?

Use a little never seize on the splines where it goes through the hub, it works well in the salt belt at keeping the corrosion out of the splines so the axles can be easily removed later.

This is what my CV looks like.



The attachment on the diff side is bolted on with a flange and there is a seal between the flange and the diff/fluid so only one side has splines.

Yep NS on the splines and a smear of grease where the seal rides is all that needs. You can use NS on everything but I prefer regular common grease with no particles (aluminum, copper, moly, etc) where the seal rides.

I know I have some grease at the house already but I can't remember what kind it is. If I don't have an NS is it safe to use a high-temp/marine grease on the splines?

I have the GM grease but I think the other is Valvoline grease.

Yes that's why I apply it with an acid brush so that just a thin coat gets applied.
