This guide covers tie rod separator vs ball joint separator. Verdict: Choose a tie rod separator if you separate tie rod ends on larger vehicles. Choose a ball joint separator if you separate ball joints on cars and light trucks, and pick the adjustable example if you want a tool that also covers tie-rod ends.
Both tools separate a tapered stud from its seat. They differ in the joint they are built for and the vehicles each listing names, and that decides which side suits your job.
