Rear End Instability?

[shlim8]

I find that my 2001 box is very sensitive to the alignment setup. I must have aligned it at least 4-5 times.... I found that each setup gave the car a different character (was varying the difference between front and rear camber). WIth almost similar negative camber front and rear, the rear was absolutely ready to swing out, especially on sweeping bends at higher highway speeds... (but definitely not understeer).

But then the suspension components esp the wishbone/control arms bushings are common failure items too.
