Alright, I found the fill plug, it looked like a newer plug and had teflon tape thred sealer on it. I unscrewed it and found grease inside the box, now I have heard that 90w oil needs to be in the YM's there but why is there grease inside my F22? At this point the steering works OK and I would really not want to remove the whole steering shaft assy to replace the grease with oil. I am thinking that possibly the steering shaft/pitman arm seal was leaky and someone just filled the box with grease? is the grease sufficiant lubrication for the bearings in there? What would you guys recomend?
