#25085, "RE: How to Replace an Inner Tie Rod (Write-Up)" In response to In response to 9
Yes, you can use a hammer to remove the tie rod ends, but it's not recommended.
If you do, you should thread the castle nut on upside down (so that it's pointing up), untill it's flat with the stud. This will help in preventing mushrooming the threads.
