2022 International LT - Wheel Alignment Specifications

Quick reference

Adjustability

On the 2022 International LT, several key alignment angles are adjustable from the factory, while others are fixed. Understanding which angles can be modified is crucial for proper alignment and diagnosing issues.

Front Axle Adjustability

• Camber: Front camber on the International LT is generally adjusted using eccentric bushings or cam bolts on the upper or lower control arms, depending on the specific suspension configuration. This allows for precise tuning to bring the wheel within the preferred range.
• Caster: Front caster is typically adjusted in conjunction with camber, often using the same eccentric bushings or shims. This adjustment is critical for steering stability and return-to-center feel.
• Total Toe: Front total toe is easily adjustable via the tie rod ends. This is the most common and frequently adjusted front-end angle.
• Individual Toe: Individual toe is adjusted through the tie rod ends.
• SAI (Steering Axis Inclination): SAI is a non-adjustable angle on the International LT. It's determined by the factory design of the steering knuckle and suspension components. If SAI is outside specifications, it often indicates bent suspension components from an impact or accident, requiring component replacement rather than adjustment.

Rear Axle Adjustability

• Camber: Rear camber on the International LT is typically non-adjustable from the factory. Any deviation from the specified range usually points to bent components or worn suspension bushings, necessitating parts replacement.
• Total Toe: Rear total toe is often adjustable on the International LT, usually through shims or eccentric bolts on the axle mounts or control arms. This helps ensure the rear wheels track correctly with the front.
• Individual Toe: Individual rear toe is adjusted through shims or eccentric bolts.
• Thrust Angle: Thrust angle is a direct result of rear total toe. If the rear toe is correctly set, the thrust angle should fall within specifications.

Recommended adjustment hardware

For most 2022 International LT alignment adjustments, the factory eccentric bolts and tie rod ends provide sufficient range. However, if significant adjustments are needed beyond the factory specifications due to extreme wear or specific operational requirements, aftermarket solutions may be considered. For persistent camber or caster issues that exceed the factory adjustment range, specialized eccentric bushings or adjustable control arms might be available from heavy-duty aftermarket suspension manufacturers.

Symptoms of bad alignment

Misalignment can manifest in several ways, often impacting tire wear, handling, and fuel economy. Recognizing these symptoms early can save you money on tire replacement and improve driving safety.

• Feathering: This indicates excessive toe-in or toe-out. The tire tread blocks will be smooth on one side and sharp on the other when felt across the tread. This can occur on both front and rear axles.
• Camber Wear (Inner or Outer Shoulder Wear): If your tires show significantly more wear on either the inner or outer shoulder, it's a strong indicator of incorrect camber. Positive camber wears the outer shoulder, while negative camber wears the inner shoulder.
• Cupping or Scalloping: Uneven wear, often appearing as dips or scoops around the tire circumference, can be caused by worn shocks, unbalanced tires, or occasionally, incorrect toe settings in conjunction with other issues.
• Steering Wheel Off Center: If your steering wheel is not straight when driving in a straight line, it's a classic sign of incorrect toe settings.
• Vehicle Pulling: If the truck consistently pulls to one side, even on a level road, it could be due to incorrect camber, caster, or an unequal toe setting.
• Loose or Wandering Steering: This often points to insufficient positive caster or worn steering components.

When to align

Regular alignment checks are crucial for maintaining the performance and longevity of your 2022 International LT. It's particularly important to get an alignment in the following situations:

• After any suspension or steering component replacement: This includes tie rod ends, control arms, ball joints, kingpins, and shock absorbers.
• After replacing tires: New tires should always be paired with an alignment to ensure even wear from the start.
• After hitting a significant pothole, curb, or obstacle: Even if no immediate damage is visible, an impact can knock the alignment out of specification.
• If you notice any of the symptoms of bad alignment: Don't wait for tire wear to become severe.
• Annually or every 12,000 to 15,000 miles: This is a good general guideline for preventative maintenance, even if you haven't noticed any immediate issues.

Typical alignment cost

The cost of a wheel alignment for a heavy-duty truck like the 2022 International LT can vary significantly based on location, shop rates, and the complexity of the alignment required (e.g., two-axle vs. three-axle alignment). Generally, you can expect to pay anywhere from $150 to $400 or more for a comprehensive alignment. This cost typically covers the labor for adjusting the accessible angles to within specifications.
