I was watching a video by Eric the Car Guy on changing a CV boot. In it he mentioned that there are two different types of grease, for inner and outer CV joints, which can be identified by the colour of the grease.
According to him "inner joint grease is yellow" and the outer grease is green.
Is this true for all axles or just for some?
EDIT
They don't sell boot kits in my country. So I have to buy the grease separately and I want to make sure I get the right one. If it matters it's for a 99 Nissan Almera which is similar to the Sentra sold in the states
EDIT 12/1/16
A search of amazon doesn't turn up anything other that CV and CV-2 grease and then there is one labelled "w/Moly". But nothing labelled inner or outer grease.
