Too Much Neg Camber?

[zebra]

I have a 86 420 SEL, and my wife bumped into curb, smashed the right front wheel and tire, the wheel point outwards ( toe-out). I went to a mechanic who charged me $250 and told me no warranty on anything he did. I only to find that he used a torch to twist the track rod and made me to risk myself in the dark ( I still keep the torched rod and don't know how to deal with him). I ordered track rod and installed it myself. Now I found it has too much negative camper. I used the eccentic bolt to adjust but seemed to me not much I can do (turned bolt all the way inwards and MB service manual said only -1 to + 0.75 degree posible). Is that the spindle damaged? I drive and it's OK. a little pull but I can adjust toe-in to compensate (actually while adjusting camper, I accidenly give too much toe-in, and it drive like having its own mind, I can turn two rounds steering without wheel response --- it's really scary and corrected my impression that more toe-in get more control of the car --- it's just opposite.

Now I observed both my upper and low ball joint are leaking ( maybe strted long ago, maybe after this bump). My question is: to cahnge these ball joints will help the camber problem or I have to buy a $400 spindle?
