It's very difficult for most of us to get this right. I don't think it's a matter of too little or too much grease. I think the instructions are vague because it's a poor design. You tighten it up too much and the wheel won't turn freely. It sticks in spots as the wheel rotates. But you loosen it up and the bearings spin against the sides of the fork. It's hard for most of us to find the sweet spot. And even then you're left wondering... how long will that last until it needs to be adjusted, as normal wear and tear take place? The video link I posted earlier shows how even in the best of circumstances, there is some shimmy caused by pinching in spots as the wheel rotates, causing the forward and backward shimmy. But after he had the wheel bearing mod done, it was dramatically improved. So I went ahead and did mine. It's great to give the wheel a spin, and like you said, it turns freely like a bicycle wheel! And these bearings will never need maintenance. There's certainly more than one way to skin this cat, but for my money, the wheel bearing mod is one of the best choices I've made.
