2018 International MV Wheel Alignment Specifications

Quick reference

Adjustability

On the 2018 International MV, front camber and caster are typically adjusted via eccentric bushings or shims, depending on the specific axle configuration. Some heavy-duty applications may utilize slotted strut towers or other specialized hardware for these adjustments. Front toe is adjustable via the tie rod ends. Rear camber is generally non-adjustable from the factory on the International MV and would require aftermarket solutions like eccentric bushings or shims if adjustment is necessary. Rear toe is also often non-adjustable, with any necessary corrections typically achieved through axle shimming or replacement of bent components. Thrust angle, while not directly adjustable, is corrected by adjusting individual rear toe to ensure the rear axle is perpendicular to the vehicle's centerline.

Recommended adjustment hardware

For most 2018 International MV trucks, factory adjustment mechanisms are sufficient for minor corrections. However, in cases of significant deviation or if aftermarket adjustability is desired, several options exist:

• Eccentric bushings: These can be used in the control arm mounts to provide additional camber and caster adjustment for both front and rear axles where applicable.
• Shims: Metal shims can be added or removed from between the frame and spring perch or other suspension mounting points to correct camber and caster.
• Adjustable tie rods: While front toe is already adjustable, heavy-duty adjustable tie rods can offer more robust and precise adjustments.

Symptoms of bad alignment

Misalignment on your 2018 International MV can manifest in several ways, often impacting tire wear, fuel economy, and steering stability:

• Feathering: This occurs when the tread ribs are worn feather-like, with a sharp edge on one side and a rounded edge on the other. It's a common sign of excessive toe-in or toe-out.
• Shoulder wear: Inner or outer shoulder wear indicates excessive camber. Inner shoulder wear suggests too much negative camber, while outer shoulder wear points to too much positive camber.
• Cupping or scalloping: Irregular dips and hollows on the tire tread (often described as looking like sections scooped out with a spoon) can be caused by worn suspension components, but also by unbalanced tires or severe alignment issues.
• Sloppy steering or wandering: If your truck feels loose on the road, constantly requires steering corrections, or pulls to one side, it's a strong indicator of incorrect caster or significant toe issues.
• Off-center steering wheel: A steering wheel that isn't straight when the vehicle is traveling straight ahead often points to incorrect toe settings.

When to align

It's crucial to have your 2018 International MV's alignment checked and adjusted in the following situations:

• After any suspension or steering component replacement: This includes ball joints, tie rod ends, control arms, shocks/struts, springs, or any other part that influences wheel angle.
• After replacing tires: New tires should always be accompanied by an alignment to ensure they wear evenly and last their full lifespan.
• After hitting a significant pothole, curb, or other road hazard: Even if there's no apparent damage, an impact can knock your alignment out of spec.
• If you notice any of the symptoms of bad alignment: Don't wait for tire wear to become severe; address alignment issues promptly.
• During routine maintenance: Many manufacturers recommend an alignment check at least once a year or every 15,000 miles, especially for commercial vehicles that experience heavy use.

Typical alignment cost

The cost of an alignment for a 2018 International MV can vary significantly depending on your location, the shop, and the extent of the adjustments needed. Generally, you can expect to pay anywhere from $150 to $400 or more. This range accounts for the complexity of aligning a heavy-duty commercial vehicle compared to a standard passenger car. If specialized hardware or extensive adjustments are required, the cost may be higher.
