I'm also interested in this, as my '99 has the same problem. Of course, it also has 265k miles, so a few things are worn. I did replace the rear struts and springs. So any help with the likely worn components is appreciated.
I will tell you this regarding front tires: If you are at a tire or aligment shop, and look on their chart of "typical problems" you won't find worn out balljoints listed. And that's the symptom of extreme wear on the inner edge of the tire. Most of the "out the door with more" tire places that include alignment will happily sell you new tires, realign, and never mention that your tires are vertically misaligned (toe). I had this happen on two sets of tires before figuring this out on my own, and had two blowouts.
About the only solution is to go to an alignment shop. If you have friends who race, they'll know the places that know alignment. Go there, and tell them your problems, and they'll fix it.
Does anyone have a rear suspension diagram they can share? I'm curious as to whats probably worn out on my car.
thx,
Sean
