You may need a torch to get the old outer tie rod ends off. Wasn't easy
each time I've done it. And no matter how good I think I've eyballed it or
counted the threads/turns, I still end up needing an alignment afterwards.
If you're talking about the S-Series, the lower ball joints are a part of
the lower control arms. You have to replace entire control arm. The upper
strut mounts actually act as the upper ball joints. To replace those,
you'll need a spring compressor and an alignment afterwards. It's not
common when they go bad, so most people wait to have them replaced until
they replace their struts.
