2020 Subaru Outback Wheel Alignment Specifications

Quick Reference: 2020 Subaru Outback Alignment Specs

These specifications are for the 2020 Subaru Outback and are intended for use by qualified alignment technicians. Values are shown in degrees.

Note: Always refer to the latest OEM service information for the most up-to-date specifications. SAI (Steering Axis Inclination) is a diagnostic angle and is not directly adjustable.

Adjustability

Understanding which alignment angles are adjustable from the factory is crucial for a proper alignment service on the 2020 Subaru Outback. Not all angles can be changed without installing aftermarket parts.

• Front Axle:

  • Camber: The front camber is adjustable from the factory. The adjustment is made via the two bolts that connect the MacPherson strut to the steering knuckle. The top bolt hole is slotted, allowing a technician to loosen the nuts and push or pull the top of the wheel to alter the camber angle. An eccentric or "cam" bolt (like the OEM upper bolt) is used to make this adjustment.
  • Toe: Front toe is the primary and most critical front-end adjustment. It is adjusted by loosening the jam nuts on the outer tie rod ends and turning the inner tie rod to effectively lengthen or shorten the steering linkage on each side.
  • Caster: Caster is not directly adjustable from the factory on this model. It is a fixed angle determined by the position of the strut top hat in the strut tower and the mounting points of the control arm. Significant deviations from the preferred caster angle often indicate bent or damaged suspension components (e.g., a control arm or knuckle) from an impact.

• Rear Axle:

  • Camber: Rear camber is not adjustable from the factory. Like front caster, it is a fixed angle. If rear camber is out of specification, it typically points to worn bushings, a bent hub/knuckle, or other damaged components.
  • Toe: Rear toe is adjustable. This adjustment is made using an eccentric cam bolt on the inboard mounting point of the rear lower control arm. By turning this bolt, the arm is pushed in or out, changing the toe angle of the rear wheel.

Recommended Adjustment Hardware

While the factory provides adjustments for front camber/toe and rear toe, sometimes issues arise that exceed the factory adjustment range, or an owner may want to adjust a non-adjustable angle.

• Rear Camber: If your 2020 Outback's rear camber is out of spec due to vehicle sag or minor component bending, an aftermarket adjustable rear lower control arm is the most common solution. Companies like SPC Performance and Whiteline offer arms that provide a significant range of camber (and sometimes toe) adjustment, allowing a technician to bring the vehicle back into alignment.
• Front Camber: For added adjustment range beyond the factory slotted strut, aftermarket camber bolts (often called "crash bolts") can be installed in the lower, non-slotted bolt hole of the strut-to-knuckle connection, providing an additional degree or more of camber change.

Symptoms of Bad Alignment

A misaligned vehicle will communicate the problem through its handling and tire wear. Watch out for these common symptoms:

• Vehicle Pulling: The car drifts to the left or right when you let go of the steering wheel on a flat, straight road. This is often caused by unequal camber or caster side-to-side.
• Off-Center Steering Wheel: The steering wheel is not straight when driving straight ahead. This is a classic sign of incorrect front or rear toe settings.
• Tire Wear: Uneven tire wear is the most concrete evidence of a bad alignment.
  • Feathering/Scalloping: Saw-tooth patterns across the tire tread are a tell-tale sign of incorrect toe. When you run your hand over the tread, it will feel smooth in one direction and sharp in the other.
  • Inside or Outside Edge Wear: Excessive wear on only the inner or outer shoulder of the tire indicates an incorrect camber setting. Positive camber wears the outside edge, while negative camber (more common) wears the inside edge.
  • Loud Tire Noise: Misalignment, particularly toe issues, can cause tires to develop wear patterns that create a rhythmic humming or "roaring" noise that gets louder with vehicle speed.

When to Get an Alignment

It’s a misconception that alignments are only needed when you feel a problem. Regular checks are key to maximizing tire life and ensuring safe handling.

• After Installing New Tires: Always get an alignment when you purchase new tires. This protects your investment by ensuring the new rubber wears evenly from the start.
• After Suspension or Steering Part Replacement: Any time a steering or suspension component is replaced—including struts, control arms, tie rods, or ball joints—an alignment is mandatory. The new parts will almost certainly alter the existing angles.
• After an Impact: If you hit a large pothole, slide into a curb, or are involved in a minor collision, the impact can easily knock your alignment out of specification. It’s wise to have it checked.
• As a Rule of Thumb: Many shops recommend an alignment check once per year or every 12,000 miles to catch any issues before they cause significant tire wear.

Typical Alignment Cost

The cost for a four-wheel alignment on a 2020 Subaru Outback typically ranges from $120 to $200. The price can vary based on your location, the shop's labor rate, and whether any seized or stubborn adjustment bolts require extra labor. This price is for the service itself and does not include the cost of any aftermarket kits that may be needed to correct angles that are not adjustable from the factory.
