Suspension grease info needed

[twoformulas]

Hi all:

I bought a replacement cartridge for my grease gun and it states to "not mix different types of grease bases." The old cartridge is NGLI #1 1/2 and is a lithium-hydroxy stearate base, and the new cartridge is a Napa brand NGLI #2 and unknown base.

This is used for greasing ball joints and steering linkage. Please educate me on this.

Thanks, Rick

USE it and just push a lot into the greaseable part. Its not gonna hurt anything heck I like to use Mobile 1 Synthetics especially if it sits or gets abused, basicly anytime.
