It's almost certain that you have a frame damage here...Pulling the frame, changing the suspension damaged components, and rebalancing will not get you back the factory balance no matter how skilled your shop is.

I had an accident few years back in a montero, and the frame got damaged. After it, the balance was never restored like factory... I was able to tell while going through the curves I used to drive, and it occasionally started to drift under pressure while previousely it never happened. Conclusion: your handling is compromised, don't take the chance - SELL IT.
