I have the notorious rear axle clicking. Nissan's is claiming it is like $100 for this stuff so I am looking for it myself.

 

I used this stuff there's no bearings or anything involved so I don't think it matters. A month and a road trip later no problems. I am usally pretty picky about oils and lubes but it seems the worst that can happen is it will start clicking again.

 

u just want something thick and water repellant so it doesnt wash away.
