2023 International MV Wheel Alignment Specifications

Quick reference

Adjustability

On the 2023 International MV, the primary adjustable alignment angles are front caster and toe. Front camber is generallynot factory adjustable and typically requires aftermarket solutions like cam bolts or eccentric bushings if it falls outside of the acceptable range and is not due to worn components. Rear toe and thrust angle are typically adjusted through loosening and shifting the axle if it's a solid axle, or via eccentric bolts on independent rear suspensions (though solid axles are far more common on commercial vehicles like the MV). Changes to SAI (Steering Axis Inclination) are usually not a standard adjustment and often indicate bent suspension components if out of specification.

Front Axle

• Camber: Not directly adjustable from the factory. Any significant deviation from the preferred specification often points to worn or bent components in the suspension system. Aftermarket camber adjustment kits, such as eccentric bushings or specialized cam bolts, may be available to correct minor camber issues without replacing major components.
• Caster: Adjustable. This is typically achieved by loosening and shifting the radius arm mounts or utilizing eccentric washers/bushings on specific suspension designs. Proper caster is crucial for steering returnability and high-speed stability.
• Toe: Adjustable. Front toe is adjusted by lengthening or shortening the tie rods. This is a critical adjustment for tire wear and steering response.

Rear Axle

• Camber: Not adjustable. As with the front, deviations typically indicate damaged components (e.g., bent axle housing).
• Toe: Adjustable. On solid rear axles, toe can often be adjusted by shifting the entire axle assembly relative to the frame. On independent rear suspension systems (less common for this class of vehicle), eccentric bolts or shims may be used.
• Thrust Angle: Adjustable. Thrust angle is corrected by ensuring the rear axle is perfectly perpendicular to the vehicle's centerline. This is often adjusted in conjunction with rear toe by shifting the axle on its mounts.

Recommended adjustment hardware

For the 2023 International MV, if front camber is out of specification and not due to worn parts, consider consulting with a truck suspension specialist. They may recommend heavy-duty adjustable cam bolts or eccentric bushings designed for commercial vehicle applications. Always ensure any aftermarket parts meet or exceed OEM specifications for durability and safety.

Symptoms of bad alignment

Misalignment can manifest in several ways, impacting vehicle handling, tire life, and fuel economy. Here are common symptoms:

• Uneven Tire Wear: The most common indicator. Specific patterns reveal specific issues:
  • Feathering: Tires have a saw-tooth appearance across the tread, typically indicating excessive toe-in or toe-out.
  • One-sided wear: More wear on the inner or outer edge of the tire, often a sign of incorrect camber.
  • Cupping/Scalloping: Irregular wear patterns of dips and hollows, which can be caused by worn shocks/struts, but can be exacerbated by or mistaken for alignment issues.
• Vehicle Pulls to One Side: The vehicle drifts or pulls to the left or right when driving on a flat, straight road, suggesting an issue with caster or camber on one side.
• Steering Wheel Not Centered: The steering wheel is crooked when driving straight.
• Loose or Sloppy Steering: The vehicle feels difficult to keep in a straight line, indicating excessive toe-out or worn steering components.
• Vibrations: While often a sign of tire balance issues, severe misalignment can sometimes contribute to vibrations.

When to align

Regular alignment checks are crucial to maintain optimal vehicle performance and tire life. You should always get an alignment:

• After replacing steering or suspension components: Any part that affects alignment angles (e.g., tie rods, ball joints, control arms, bushings, shocks/struts) should be followed by an alignment.
• After replacing tires: New tires are an investment; protect them with a fresh alignment.
• After a significant impact: Hitting a large pothole, curb, or being involved in an accident can knock your alignment out of specification.
• If you notice any of the "Symptoms of bad alignment" listed above.
• At recommended service intervals: Many manufacturers and shops recommend checking alignment annually or every 15,000 to 20,000 miles, especially on commercial vehicles subjected to heavy loads and varying road conditions.

Typical alignment cost

The cost of an alignment for a 2023 International MV can vary widely depending on your location, the shop, and whether it's a basic two-wheel (front) or a four-wheel alignment (which is recommended for commercial trucks to address potential rear axle thrust issues). Generally, you can expect to pay anywhere from $150 to $400 or more for a complete commercial vehicle alignment. This price may increase if specialized adjustments or aftermarket parts are required. Always get a detailed quote before authorizing any work.
