2021 Honda Civic Wheel Alignment Specifications

Quick reference

These specifications are for the 2021 Honda Civic and should be used as a guideline. Always refer to the specific recommendations for your vehicle's trim level and any modifications. All values are in degrees.

Adjustability

Understanding which alignment angles can be adjusted on your 2021 Honda Civic from the factory is key to diagnosing issues and planning for any necessary repairs or modifications.

Front Axle:

• Toe: This is the primary and, from the factory, the only adjustable angle on the front of a 2021 Civic. The adjustment is made by loosening the jam nuts on the inner tie rods and turning the rods to lengthen or shorten them, pushing the front of the tires inward or outward.
• Camber & Caster: These angles are not adjustable from the factory. They are determined by the manufacturing tolerances of the strut, knuckle, and control arms. If your Civic's front camber or caster is out of specification, it typically indicates that a component has been bent or damaged from an impact (like hitting a curb or pothole) or is worn out. To correct out-of-spec front camber, aftermarket solutions are required.

Rear Axle:

• Toe: The rear toe is adjustable. This is typically accomplished using an eccentric bolt located on one of the rear control arms. A technician can loosen the bolt and rotate it to shift the arm, thereby changing the rear toe angle.
• Camber: Like the front, rear camber is not adjustable from the factory. An out-of-spec rear camber measurement often points to worn-out bushings or damage to a control arm or the knuckle. Aftermarket parts are necessary to make rear camber adjustable.

Recommended adjustment hardware

If your alignment check reveals that camber is out of specification on either the front or rear axle, and no components are found to be bent or broken, you will need to install aftermarket parts to make it adjustable.

• Front Camber: The most common and cost-effective method for adding front camber adjustment is to install aftermarket camber bolts (often called "crash bolts"). These bolts have a smaller shank diameter than the factory bolt, with a cam lobe on the head. When installed in the upper hole of the strut-to-knuckle connection, rotating the bolt shifts the top of the knuckle inward or outward, allowing for about +/- 1.5 to 2.0 degrees of camber change. Brands like SPC (Specialty Products Company) and Eibach offer reliable kits.
• Rear Camber: The best solution for correcting rear camber is to install adjustable upper control arms. These arms replace the factory, fixed-length arms and feature a threaded design or eccentric bushings that allow you to precisely lengthen or shorten the arm, thereby changing the camber angle. This is a more involved installation than front cam bolts but provides a wide range of adjustment and is the correct way to solve rear camber issues.

Symptoms of bad alignment

Your car will often give you clear signals when its alignment is off. Ignoring these can lead to unsafe driving conditions and expensive tire replacement.

• Vehicle Pulling: The most obvious sign is the car drifting or pulling to the left or right when you are trying to drive straight. This is often caused by unequal camber or caster side-to-side.
• Off-Center Steering Wheel: If your steering wheel is crooked when you're driving in a straight line, it's a sure sign that the toe angles are off.
• Uneven Tire Wear: A visual inspection of your tires can reveal a lot about the alignment.
  • Inner/Outer Edge Wear: If the inside shoulder of the tire is worn, it indicates excessive negative camber. If the outside shoulder is worn, it indicates excessive positive camber.
  • Feathered/Saw-Tooth Wear: If you run your hand across the tread of the tire and it feels smooth in one direction but sharp and jagged in the other, this is called feathering. It's a classic symptom of an incorrect toe angle, which causes the tires to scuff sideways as they roll forward.

When to align

It is crucial to have your vehicle's alignment checked regularly and after specific events.

• After Installing New Tires: To protect your investment and ensure a long life for your new tires, an alignment is highly recommended.
• After Suspension or Steering Work: Any time a steering or suspension component is replaced (e.g., struts, control arms, ball joints, tie rods), the alignment will be affected. A full four-wheel alignment is mandatory after this type of work.
• After an Impact: If you hit a significant pothole, run into a curb, or are involved in a minor collision, the impact can easily knock your alignment out of specification.
• When Symptoms Appear: If you notice any of the symptoms listed above—pulling, an off-center steering wheel, or uneven tire wear—you should have the alignment checked immediately.

Typical alignment cost

The cost for a professional four-wheel alignment on a 2021 Honda Civic typically ranges from $100 to $250. The price can vary based on your location, the type of shop (dealership vs. independent), and the specific equipment they use. If adjustable aftermarket parts are required, you will also have to factor in the cost of those parts and the additional labor to install them.
