That's the outer tie rod.
Get Moog parts with grease-able / serviceable joints. Well worth the cash and should last you quite a bit. As far as the job being involved, if you've never touched a suspension component, it can take a little figuring out. You may need to use some heat on the tie rod in order to get the locking nut to release. Also consider soaking them in PB Blaster. Then, you should be able to spin the tie rod itself off of the power steering arm. Make sure you count the turns and try and match it when you install the new ones.
End-links are straight forward - use a wrench to loosen the nut on both ends, remove nut, remove endlink, install new ones.
