2021 Subaru Outback Wheel Alignment Specifications

Quick reference

Adjustability

The 2021 Subaru Outback offers a good degree of factory adjustability, though some angles will require aftermarket solutions for significant changes.

• Front Camber: From the factory, front camber on the 2021 Subaru Outback is not directly adjustable. Minor changes (typically less than +/- 0.5 degrees) can sometimes be achieved by shifting the subframe, but for more significant adjustments, aftermarket camber bolts (e.g., SPC, Ingalls) are typically required. These replace the upper strut bolt, allowing eccentric adjustment.
• Front Caster: Similar to front camber, front caster is not directly adjustable from the factory. Any significant adjustments would necessitate aftermarket control arms or caster-correcting bushings.
• Front Individual Toe: Front toe is fully adjustable via tie rod ends on both sides. This is a standard and straightforward adjustment.
• Rear Camber: Rear camber on the 2021 Subaru Outback is adjustable using an eccentric cam bolt located on the lower control arm. This allows for fine-tuning within the factory specified range.
• Rear Individual Toe: Rear toe is fully adjustable via eccentric cam bolts on the rear lower control arms.
• Thrust Angle: While not directly adjustable, thrust angle is a result of the rear toe settings. Ensuring the rear individual toe settings are correct and balanced will result in a zero or near-zero thrust angle.

Recommended adjustment hardware

For most routine alignment scenarios, the factory adjustments on the 2021 Subaru Outback are sufficient. However, if you've installed a lift kit, lowered your vehicle, or are experiencing persistent alignment issues outside of the factory adjustment range, you might consider:

• Front Camber/Caster Correction: Aftermarket camber bolts (e.g., SPC Performance, Whiteline) for the front struts can provide a few degrees of camber adjustment. For more extensive caster and camber changes, adjustable lower control arms are an option.
• Rear Camber/Toe Correction: While the rear is adjustable, if you've significantly altered the ride height, extended range eccentric lockout kits or adjustable control arms might be needed to bring the angles back into specification.

Symptoms of bad alignment

Recognizing the signs of a misaligned vehicle can save you money on tires and improve driving safety:

• Uneven Tire Wear: This is the most common indicator. Specific patterns can point to specific issues:
  • Feathering: Sawtooth-like wear across the tread, often indicating excessive toe-in or toe-out.
  • Cupping/Scalloping: Pothole-like dips in the tread, often a sign of worn suspension components, but can be exacerbated by alignment issues.
  • Inner or Outer Edge Wear: Excessive positive or negative camber will cause accelerated wear on one edge of the tire.
• Vehicle Pulling or Drifting: If your Outback consistently pulls to one side when driving on a flat road, it's a strong sign of an alignment issue, often related to camber or caster differences between the front wheels.
• Steering Wheel Not Centered: Even when driving straight, a misaligned vehicle might have an off-center steering wheel.
• Loose or Sloppy Steering: While often indicative of worn steering components, alignment can contribute to a less precise steering feel.

When to align

It's recommended to have your 2021 Subaru Outback's alignment checked in the following situations:

• After Replacing Steering or Suspension Components: Any work involving tie rods, control arms, ball joints, struts, or springs necessitates an alignment.
• After Purchasing New Tires: To ensure maximum tire life and even wear.
• After an Accident or Hitting a Large Pothole/Curb: Even a seemingly minor impact can throw off your alignment.
• Every 12-15,000 Miles or Annually: Regular checks can catch minor issues before they become major problems.
• If You Notice Any of the Above Symptoms: Don't wait; get it checked promptly.

Typical alignment cost

The cost of a wheel alignment for a 2021 Subaru Outback can vary depending on your location, the shop, and whether any seized components require extra labor. Generally, you can expect to pay anywhere from $90 to $150 for a standard four-wheel alignment. Some shops offer lifetime alignment packages, which can be a good value if you plan on keeping your vehicle for a long time or frequently encounter conditions that necessitate alignments.
