Although removing the u-joint and reinstalling it in the correct orientation would be the "right" way to do it, I am still going with the grease needle solution. You must have a different type of needle than I do. Mine is a cylinder that only tapers down to a point the last quarter inch or so. You would have to try pretty hard to bend this thing. I have to remove the "stock" end from my grease gun hose then thread the "needle" on to the end of the hose. It's what I use on my u-joints that I apparently installed wrong and it works well.
