+1 That's what I used on my 400 when I had it. That's one of those "Snake Oil" items that lives up to all their claims. I love the stuff been using it for 20+ years. :thumbup:Instead of lube I use Anti seize, just put a thin coat on the spline with a small brush. It will not get gummy after time like grease will. You can pick it up at any auto parts store.
