The ball joints come from the factory with a thread for a grease nipple, but it's plugged with a small bolt. You just have to remove the bolt, install a 45 degree grease nipple and then keep them greased.
Interesting point ... yes - and that was done at the VERY first service I had on my then brand new 4Runner at the dealership who told me I HAD to install nipples (I did so but asked why, if it was so important, didnt they come factory installed?) .. AND all the joints (plus cardan) were then routinely greased with synthetic (at least every 3 months) .. AND vehicle never forded. I was PRETTY damn surprised when I was called by the dealer, that I traded it to, who was pretty curt about the ball joints they said they had to replace at 114k km... WTF
