i've mentioned this before, but could it be the tire? when i first did my suspension, i got it aligned and it was straight and didn't have any tire issues, and the tires were bad/bald. i didn't have problems with the old tires. i get new tires, problems start. i checked and rechecked control arm bushings, rack bushings, struts, etc, and nothing. everything is tight. i am at a loss here.
