It's pretty trivial. Get a tie rod end removal tool (rent/borrow from the parts store if you don't want to buy one.) and press it out of the mount. Loosen the jam nut that stops the tie rod end from rotating, but be very careful to keep it from moving on the threads when you unscrew the unit from the inner tie rod.
Then preposition the jam nut on the NEW one to the same distance as the old one, so when you put it all together, you will have about the same toe-in as before. Grease the new one if you bought one with zerks.
Then get an alignment ASAP before driving long distance, because it's very tough to get toe-in right by eye.
