The squeak you hear is it when you have steering wheel turned? If si it's NOT the grease fitting it's the steering stop which is I think on the lower susp arm. They wear out over time. Some people just slap a little grease there others put a gob of silicone. As to not able to get grease in the little grease zirk, it probably got some real Old hard grease gunk in it. You may need to push real hard or think about getting it fixed sometime. Maybe someone with a air grease gun may have enough force to free it. <img src="/forums/images/graemlins/patriot.gif" alt="" />
