Recommended Alignment Specifications for a 2008 Subaru Outback
Subaru introduced the Outback in 1995, at a time when the SUV market was growing at a rapid pace. The Outback offered the elevated suspension and all-wheel-drive of SUVs without the bumpy rides or low gas mileage of contemporary SUVs. The Outback was the first sport-utility wagon and was highly influential in the development of the crossover SUV wagon. The 2008 Outback came in eight different trims, but the alignment specs were the same for all trims.
Caster
The caster angle is the slope of an imaginary line drawn through the upper and lower steering pivots of a wheel, with zero axis being a perpendicular axis line drawn straight up from the ground through the center of the wheel. For instance, if the steering pivot line passes through the perpendicular line at five degrees toward the rear of the car, then the car has a caster of +5 degrees. If it passes through the perpendicular axis line at five degrees toward the front of the car, the car has a caster of -5 degrees. The ideal caster angle for the 2008 Subaru Outback is +4.92 degrees, but it can range 0.75 degrees in either direction.
Camber
When standing in front of a vehicle, the camber is the angle at which the wheels lean. If the top of a wheel leans in toward the engine block, the wheel has a negative camber. If the top of the wheel leans out away from the engine block, it has a positive camber. The ideal camber angle for the front end of the 2008 Subaru Outback is +0.67 degrees but it can range by 0.5 degrees in either direction, with a cross tolerance of 0.75 degrees. The ideal camber on the rear end is -0.17 degrees, but it can range 0.75 degrees in either direction.
Toe
The toe is the angle of the wheels in relation to the centerline of the vehicle. Most vehicles are designed to toe-in, meaning the fronts of the wheels when angle slightly inward toward each other and the centerline of the vehicle. Perhaps counter-intuitively, this inward angle is give in positive degrees. A vehicle with a toe-in of +1.0 degrees has wheels that angle slightly toward each other. Toe-out, wheels intended to angle away from each other at their fronts, is represented in negative terms and is rare. The ideal toe on the front end of the 2008 Subaru Outback is zero degrees but it can range by 0.16 degrees in either direction. The ideal toe setting on the rear end is -0.13 degrees but it can range by 0.13 degrees in either direction. Again, this is a rare setting, and the negative measurement means that the fronts of the tires should point away from each other at a -0.13 degree angle.
