I have the calmini ss on my x. I feel a clunk when turning at low speeds. While taking a look under the front end today i noticed that both the ball joints on the calmini center link had grease coming out of them. I tightned these things down correctly when I put it on. I notice that they have a zerk. Is this common for them to do that and should i just put more grease in them? If they are bad, then i'm pretty sure that they are causing my steering clunk. Whats the part number if they are bad, so i can replace them. thanks
