Grease specs?

[00pathyse]

I have NLGI GC LB grease I was going to use in the prop shaft. How do I know if that meets NLGI 2 specs. Thanks.

Nearly all grease is No. 2. You can try Googling for the product data sheet of the grease you bought.

[00pathyse]

Thanks. Do you know how much I should put in? Do I just keep adding until I see some come out? Im not sure if there is any seals in there or not.

[Towncivilian]

I just put 4-5 pumps in and call it good. Grease it every oil change from now on, or as soon as possible after potential water entry.

[00pathyse]

Thanks will do. I don't think it's been done since we've owned it. I'm very tempted to keep pumping grease in there until I see the old stuff start coming out. Do you ever see any grease ooze out when you're doing yours?

[Towncivilian]

Nope, I've never seen any grease come out even after 10 to 12 pumps. I don't think it's supposed to come out of the seal. Which driveshaft are you greasing?

[00pathyse]

There is just the one, just in front of the transfer case. (4wd). I did 8-10 pumps and a little bit of air and dirty greased escaped out the front of the rubber sleeve ahead of the lube fitting.

There is just the one right??

[Towncivilian]

Yes, there is just one on 4WD Pathfinders, on the front driveshaft as you described.

[00pathyse]

Anyone know why 03 Pathfinders owner manual doesn't specify Moly grease for the prop shaft but other years do?

[Towncivilian]

Probably so the dealerships would only need to have a single type of grease on supply. I can't imagine there being any significant differences between the years, especially one where molybdenum would be incompatible. Use any grease you wish, just don't mix base types (i.e. mix a calcium sulfonate grease with lithium complex grease).

[00pathyse]

Yea doesn't make sense does it. I used another lithium based grease. Cheers.
