Tie rod ends are the same as ball joints, right?
If so, ring Nissan, they can organise those for you.
Otherwise do what I suggested before when you PM'd me, and search.
People here are happy to help, but you have to try and do some research.
Searching for ball joints found my thread from two months ago, and also enlightened me on my irritating wiper problem. Awesome!
And not sure where that relay was, but looks like the 4WD relay to me.
