Toyota CV boot kit - Which grease to use?

    Automotive CV joints come in two different Types:

    1. Ball-type (Outside)
    2. Tri-pod type (Inner)
    Every front wheel drive vehicle you see has a CV joint on each end of the driveshaft. The inner CV joint connects the driveshaft to the transmission, and the outer joint connects the driveshaft to the wheels.

    When purchasing a CV Boot Kit from your Local Toyota Dealer Parts Department, you may notice that there are two color (types) of axle grease contained in the kit. Which one goes to which?

    There is a saying that most Toyota Techs know... "Thinner is inner". This means that if you looked at the viscosity (feel) of the grease, you should notice a difference. Thus the expression.

    Also, if you look at the color, Tan grease is for the inside joint (closest to the transmission), black grease for the outside joint (closest to the wheel).

    I have toyota cv axle boot kit for 09 corolla. The grease looks very similar NKG302 and NKG 509. Which grease goes to the inner and outer cv's?

    Ronald, you can check with your local Toyota Dealer parts dept to be 100% sure. Techs just usually go by the "thinner is inner" notation.
