first thing.get the steering alingment set up by a four wheel laser system and a trully compotent tech.it entirly possible to have the front wheel alingment correct and wrong at the same time.a rough check is to count from straight ahead the precisce ammount of turns (complete and fractional)the steering wheel takes till full lock oneither side.they should be exactly the same.further.weak springs /shock absorbers can create ur symptoms.assuming it dosent have a bent chassis(which ur local accident repair center with alignment bench can check)your best bet is your local motor sport specialist.those guys have test guages u would not believe.bad handleing loses races.they can check trail and camber and many other things ur average mech has only heard about.one last thing ,had one job once similar .turned out to be faulty diferential.so u never know .
