Front End Alignment: Toe Adjustment
Incorrect toe settings can result in major tire wear. The vehicle's tire tread will show diagonal scuffing and feathering. Check this by running your open hand across the tread of each tire checking for tire feathering, cupping, and unusual wear.
One could think of vehicle toe as an imaginary line drawn down the center of the tire and another imaginary line drawn down the center of the vehicle. If the tire is toed in, the two imaginary lines would intersect. If the tire were toed out, the line through the tire would angle away from the center line of the vehicle.
Adjust the toe by turning the inner tie rod on a rack and pinion steering system and by turning the adjusting sleeve on a parallelogram linkage system. To adjust the toe on a vehicle with a typical rack and pinion system, loosen the nut on the inner tie rod about a half inch from the outer tie rod end. Loosen the clamp holding the bellows boot and make sure the boot is free (not sticking) to the inner tie rod. Typically the technician will turn each inner tie rod one half of the total toe specifications and split the toe between the two tires. Tighten the lock nut and replace the clamp, then bounce the vehicle and check the toe again. Always lock the steering wheel with a steering wheel lock correctly wedged between the seat and the wheel.
