Yeah this is an old thread but I am throwing this into the pot.
I found it easier to replace the whole ( lower) arm.
Look at it this way. New bushings and ball joint pressed in for twice the cost of the joint alone.
The tricky part is releasing the tension on the torsion bars, but believe me doing it this way will save labor hours and get the front end a lot tighter. Your control arm bushings are 16 years old.
Also, since the uppers are also removed, re install using camber adjuster shims. This will allow a better alignment,and, they should not charge any additional labor to install them over the upper ball joint(s) labor charge, as the adjuster kit is basically a different style of mounting bolt for the upper arms.
