Thanks all for the nice welcome, most appreciated!

Let me begin by saying that if a less experienced driver had been steering my wifes 2003 zx5 around the off ramp when it hit a small bump, they might not have made it! It was like the whole back end jumped up and shifted a 1/2 foot.
That sounds like I believe I am as good as Mario Andretti. No, I don't believe that for a second. I have had my share of cars though and I have never experienced the back end going out on me like that before ...ever.
Yes, when I was younger I pushed the limits every time I got out for a spin but this was not the case on that and subsequint occasions.
Prior to that my wife had complained several times before I finally agreed to check it out.
Once that happened to me I have changed tires and shocks to try to hammer out the problem...to no avail.
So at this point, if I don't come up with a cost effective sollution I will have to dump the car for saftey concerns.
I very much look forward to your constructive comments.
Cheers,
Steve
