If the grease doesn't work (didn't for me) don't mess with it, just buy a new one and install. Takes a couple of hours depending on how much you have to drink
. It really is simple, just make sure you tie (or duct tape) a good rope to the end of the old one and pull it out. Then attach the new one to the rope and pull it back through. And then your steering will be good as new! Makes a HUGE difference.
