Also, I want to add that there is a cotter pin that you have to remove first before unscrewing the nut.
The tool used for this purpose is:
But I also used a simple 3-jaw puller to do the job. Tried it with a hammer and pry bar, and none of those work.
Some tips:
1) Put a rag around the tie rod when pulling it out with a tool.
It can "fly" off and hit you or the inside of the wheel well somewhere.
2) If you are replacing with a stock outer tie rod end (therefore assuming same length), then simply use white-out to mark the nut next to the tie rod end to the tie rod.
Then loosen that nut to remove the old tie rod. Line it back up after installing the replacement tie rod. You will approximately be in the same place. You still want to get an alignment, though, as you should with any changes to the suspension.
