If they don't have the Allen hex hole they have flats for an open wrench on the side of the ball joint. You need a wrench that is not too thick so you won't damage the rubber over the ball joint. The new nuts are safety nuts that won't come loose. That means they are not all that easy to tighten.Murdoc wrote:I already bought new ones, I don't have an impact, I read you can vice grip one side and it stops the allen bolt from spinning and just take the nut off that way. The new ones I got don't have the allen bolt hole they will be much easier to install!
