I think Ol Jenny is asking about the grease passages drilled into the shackle shank.

I didn't really pay attention to mine when i replaced them and they take grease normally.

You might try having someone rock the body back and forth while you try to force the grease in.

It might be a little tricky..

I use a grease gun with a needle tip as I have a variety of grease fittings on my truck...
