Adjustability
The 2018 International LT offers a limited range of factory adjustments.
- Front Axle: Caster and toe are the primary adjustment points on the front axle. Caster is adjusted via the slotted brackets on the axle, while toe is adjusted by turning the tie rod ends. Camber and SAI are not directly adjustable and are set by the factory. If camber is out of specification, it typically indicates bent or worn parts that need replacement, such as the axle beam, knuckles, or kingpins.
- Rear Axles: The rear axles on the International LT are not adjustable for camber or caster. Toe and thrust angle can be adjusted by loosening the axle U-bolts and shifting the axle position slightly. This is a complex procedure that should only be performed by an experienced technician.
Recommended adjustment hardware
For vehicles with camber outside of the acceptable range due to minor deviations in the axle or suspension components, eccentric bushings can be installed in the kingpin bores to provide a small amount of camber and caster adjustment. However, the preferred solution is always to identify and replace any bent or worn components.
Symptoms of bad alignment
Misaligned wheels can cause a variety of issues, including:
- Uneven tire wear: This is the most common symptom of bad alignment.
- Camber wear: Wear on the inside or outside shoulder of the tire indicates a camber issue.
- Toe wear: A "feathered" or "sawtooth" wear pattern across the tread is a sign of a toe problem.
- Caster wear: Caster does not directly cause tire wear, but incorrect caster can lead to other issues that do.
- Steering pull: The vehicle may pull to one side while driving.
- Wandering: The vehicle may feel unstable and wander from side to side.
- Off-center steering wheel: The steering wheel may not be straight when the vehicle is driving straight.
When to align
It is recommended to have your alignment checked at least once a year or every 100,000 miles. You should also have your alignment checked after:
- Installing new tires
- Any suspension or steering repairs
- Hitting a large pothole or curb
- Noticing any of the symptoms of bad alignment
Typical alignment cost
Heavy-duty truck alignments are more complex and time-consuming than passenger car alignments. The cost for a three-axle alignment can range from $300 to $600, depending on the shop and the extent of the adjustments needed.
