I have a 1999 LS400 with 156K. Still in beautiful condition. I had the strut/tie rod bushings replaced at 104K. I'm starting to get some vibration just like when I had the bushings replaced before; could they need replacing again? The car leads a pretty easy life. Also, it's starting to feel sort of boatlike; I'm assuming the shocks (not air suspension) need to be replaced. My indie shop says $2,300...really? Interested in everyone's experience.
