Wheel Alignment: Rear Toe
The toe setting of an independent rear suspension vehicle will affect the vehicle's thrust angle. This will result in excessive tire wear. In the illustration, the toe out setting wore the inside tread of the left rear tire almost bald. This toe out could have been caused by a bent or worn component. Manufacturer’s include a rear toe adjustment on vehicles with independent rear suspension. Adjust toe by turning a tie rod or an eccentric cam located at the wheel being adjusted.
Rear toe is checked and set before a front end alignment is performed. Front toe is the last and most likely angle to require adjustment. Alignment racks display angles in fractions of inches (1/4), but many alignment racks today use degrees (°). Toe in is considered positive toe (+) and toe out is considered negative toe (-). A vehicle’s rear toe setting has an effect on its steering wheel position.
