International 2375 S Steering King Pin Sets

International 2375 S Steering king pin sets

Starting at low prices, AutoBuffy stocks multiple steering king pin sets from top OE-quality brands for the International 2375 S. King pins are the vertical pivot pins connecting the steering knuckle to the front axle on solid-axle vehicles. When they wear, the front wheels develop dangerous play, causing unpredictable steering and accelerated tire wear.

Signs your International 2375 S needs new steering king pins

  • Excessive play or looseness in the steering wheel that doesn't respond to tie rod or wheel bearing replacement
  • Clunking or knocking noise from the front axle when turning or hitting bumps, especially at low speed
  • Front tires showing uneven or feathered wear on the inner or outer edge despite correct alignment
  • Visible wobble or shimmy in the front wheels when driving at highway speeds or over rough pavement
  • Front end pulls to one side during braking as the worn pin allows the knuckle to shift under load
  • Grease leaking from or absent at the king pin grease fittings, indicating the bushings are dry and wearing rapidly

Which steering king pin set should you buy for your International 2375 S?

King pin sets vary primarily in bushing material, inclusion of shims and caps, and whether they meet OEM or upgraded heavy-duty specifications. The right choice depends on how the International 2375 S is used — daily street driving, towing, or off-road work — and whether you want a direct OEM replacement or improved durability over the original design.

King pin replacement on the International 2375 S requires removing the front wheel, separating the steering knuckle from the axle beam, and pressing out the old pins and worn bushings with a hydraulic press — hand tools alone will not do the job safely. New bushings must be pressed in square, reamed to size if required, and the pins installed with fresh seals and correctly sized shims to eliminate end play. Torque all fasteners to the manufacturer's specification and grease all fittings thoroughly before lowering the vehicle and scheduling a front-end alignment.

Frequently asked questions

How much does it cost to replace steering king pins on a International 2375 S?
Parts start at low prices for a International 2375 S king pin set at AutoBuffy. Add shop labor — king pin replacement is a precision job requiring a hydraulic press to remove and install pins and bushings, so professional labor costs are typically significant. Doing it yourself with the right tools keeps the total cost closer to the parts price alone.
How long do king pins last on a International 2375 S?
King pin lifespan varies widely based on use and lubrication habits. On a well-maintained International 2375 S that is greased at every service interval, king pins can last many years. Off-road use, heavy towing, or neglected grease fittings can cut that lifespan dramatically — sometimes to a fraction of normal service life.
Can I drive my International 2375 S with worn king pins?
No. Worn king pins on a International 2375 S are a serious safety hazard. Excessive front-end play reduces your ability to steer accurately and extends stopping distances. Under hard braking or during a sudden maneuver, a badly worn king pin can allow enough knuckle movement to cause loss of directional control.
Do I need an alignment after replacing king pins on a International 2375 S?
Yes, always. Replacing king pins on the International 2375 S changes the geometry of the front steering knuckle and axle interface. Even if the new parts are dimensionally identical to the originals, caster and camber can shift. A professional front-end alignment after installation is required to restore correct tire wear and straight-line tracking.
Are king pins the same as ball joints on a International 2375 S?
No. King pins are used on solid front axles — common on older trucks, heavy-duty pickups, and 4WD vehicles. Ball joints perform the same pivot function on independent front suspension designs. The International 2375 S will have one or the other, not both. Check your front axle type before ordering to confirm which applies.
How do I check king pin wear on my International 2375 S?
Support the front axle of the International 2375 S on jack stands, then grip the front tire at the 12 and 6 o'clock positions and attempt to rock it. Movement here indicates king pin or bushing wear. Compare the measured play at the tire to the manufacturer's service limit for your axle — any perceptible rocking typically warrants inspection.
