Depends, have you had other suspension components replaced before? If you know the history of the car and are running on original suspension, you're definitely on borrowed time.
My 2003 car had 113K when I did this job, the thrust arm's ball joints which I replaced with new were literally wobbling. I know the rest of my suspension is probably in the same condition or worse. If I were you, I would start with the thrust arms (even if they were replaced, they typically have to be renewed again every 75K), but plan to replace most of the front and possible rear suspension.
Just typing those words, gives me pause thinking about the mountain of work that lay ahead for me in the not too distant future!
