I'm almost out of Redline CV2 and am in the process of rebuilding a prop shaft for someone, my question is can I use my Mobil 1 synthetic grease? CV2 is a NLGI 2 grease with service rating GC LB, the tub on my Mobil 1 grease says it exceeds GC LB service rating but does not say specifically if it is a NLGI 2 grease.

My question is would it be ok to use the Mobil 1 grease or just wait for delivery of the Redline grease I ordered?

Mr.Matchbox

At the mobil Homepage the Mobil 1 grease is also rated as NLGI 2:

Greases are not always compatible with each other.

Redline says its compatible with *most*.
Not sure what M1 says.
Not sure what both contain.

I would just order more redline on Amazon and have 1 or 2 day delivery.

Or use all M1 if you haven't started yet.

The proper grease for a tripod 'cv' joint is nlgi#1. When people use cv-2, they are technically using the wrong grease. It seems to work though.

More important that NLGI rating is base oil of the lubricant in the grease. There are ranges in the NLGI scale and unless you're comparing the actual penetration numbers there is room for ambiguity.

Sure can relate to THAT

I washed the bearings on the prop shaft in mineral spirits then packed them with Redline I had just enough to do both CVs.

Be careful with the snap rings, they're easy to permanently distort.

Yes , penetration numbers can be worrisome...Pete

Speak for yourself. I recently performed this operation. Made careful consideration before choosing my lubrication, and I have to say I'm confident in my penetration...
