Ball joint??

[gt95coupe]

Is the ball joint on the ls' greaseable? Ive been seeing a lot of threads on noises caused by a bad ball joint or is it a non-greaseable "no maintenience" self greasing type. On another note are there any zerk fitings on the ls

ball joint is sealed. appears most all of the greased susp parts are sealed (tie rod ends, sway bar links, etc).
