tie rod

I just changed front brake pads and rotors today and I noticed the passenger side tie rod ball joint is leaking grease. Here are some pics. I have been hearing mysterious rattling noise from that side at speed over 40 miles per hour and mechanics told me to replace brake pads, rotors and struts...

Ok got a question or two for whoever has experience replacing the outer tie rods. 1.is it really as easy as Chilton/Haynes claims it to be. 3-4 steps not including taking off the tire. 2.should I replace the inner tie rods at the same time? The mechanic at the alignment shop didn’t say if...
