You might try this suggestion. It worked for my older 4X4 and my '99 Taco.
"Get the front end alignment checked. Find a shop with a Hunter alignment rack. Get a 4-wheel thrust alignment where they precisely measure the exact direction of thrust of the rears and align the fronts to that. Have the shop align the toe-in and camber to the exact center of the spec, and set the caster to the maximum allowable. The factory specs are too wide for good alignment, so just setting to "factory spec" is not acceptable. What I listed above are within factory spec, so the shop has no beef."
