The King Pin Kit with reference code MM-09 and OEM number MB294272 is a verified direct-fit replacement for Mitsubishi Fuso Canter light and medium-duty trucks equipped with 4D31 / 4D32 / 4D33 / 4D34 diesel engines. This king pin kit is a critical steering knuckle component that connects the front axle to the steering knuckle, allowing the front wheels to pivot for steering while supporting the vehicle's weight.
The king pin kit serves as the pivot point for the steering knuckle on the front axle. It allows the knuckle to rotate for steering while maintaining precise alignment between the axle beam and the knuckle assembly. The king pin must withstand both vertical loads (vehicle weight) and horizontal loads (steering forces, braking forces, and road impacts). The MM-09 kit includes a Φ28*180 mm hardened 40Cr alloy steel king pin, bronze bushings, thrust bearings, shims, seals, and mounting hardware. The rubber O-rings and seals prevent contamination from entering the bushing area, while the thrust bearing supports the vertical load and ensures smooth steering rotation. The 4D31 is a 3.3L inline-four diesel engine, the 4D32 is a 3.6L variant, the 4D33 is a 4.2L engine, and the 4D34 is a 3.9L engine, all widely used in Mitsubishi Fuso Canter trucks from 1984 to 2016.
Replace the king pin kit when any of these symptoms appear:
Steering wander or excessive steering play — worn king pin bushings allow the knuckle to move, causing the vehicle to wander on straight roads.
Uneven or accelerated front tire wear — misaligned knuckle geometry from worn king pins causes cupping or scalloped tire wear patterns.
Front end shimmy or vibration — loose king pins allow the front wheels to oscillate at certain speeds.
Hard steering or binding — seized or corroded king pins prevent smooth steering operation.
Clunking or knocking noise from the front axle — excessive clearance between the king pin and bushings causes metal-to-metal contact.
⚠️ Critical Inspection Note: Mitsubishi service manuals require that the king pin be replaced, never reused, when the knuckle is removed. Always replace king pins, bushings, bearings, and seals as a complete kit. Inspect the axle beam king pin bore for wear or elongation — if damaged, the axle beam must be replaced. Always use new king pin bolts and nuts. After installation, a professional wheel alignment must be performed to restore correct steering geometry. Press-fit the kingpin bushing so that the gap between the bushing and knuckle is within 0 to 1 mm (0 to 0.039 in.) .

⚠️ IMPORTANT: King pin replacement is a professional-level steering system repair. It must be performed by a qualified technician in a clean workshop. Always replace king pins, bushings, bearings, and seals as a complete kit. Never reuse old king pins or fasteners.
Preparation: Raise the vehicle on a hoist. Remove the front wheels. Support the front axle. Disconnect the steering linkage from the knuckle.
Disassembly: Remove the king pin lock pin. Remove the king pin cover plates (top and bottom). Press the old king pin out using a hydraulic press or king pin driver. Remove the old bushings, bearings, and seals.
Inspection: Inspect the axle beam king pin bore for wear, elongation, or scoring. Measure the bore diameter. Inspect the steering knuckle bore for wear. If the knuckle bore is worn beyond the oversize kit range, the knuckle must be replaced.
Bushing Installation: Press the new bushings into the knuckle. Press-fit the kingpin bushing so that the gap between the bushing and knuckle is within 0 to 1 mm (0 to 0.039 in.) . Do not ream unless specified by the bushing manufacturer. The bushings are pre-sized for the king pin diameter.
Grease Fitting Installation: Install the grease fitting into the knuckle.
King Pin Installation: Lubricate the king pin and bushings with chassis grease. Insert the shim on the upper side of the thrust bearing and install the king pin. Install the thrust bearing on top of the knuckle.
Lock Pin Installation: Align the king pin cut groove and lock bolt hole, tighten the lock bolt, and lock by tightening the lock nut.
Cover Plate Installation: Install the king pin cover plates and gaskets. Tighten the bolts to specification.
Steering Linkage Reconnection: Reconnect the steering linkage. Tighten the retaining bolts to specification.
Greasing and Road Test: Grease the king pins through the fittings. Lower the vehicle and perform a road test to verify steering operation. Perform a professional wheel alignment.
Recommended Torque Values:
| Fastener | Torque |
|---|---|
| King Pin Lock Pin Lock Nut | Per Mitsubishi workshop manual specification |
| King Pin Cover Plate Bolts | Per Mitsubishi workshop manual specification |
| Steering Arm Retaining Bolts | Per Mitsubishi workshop manual specification |
Every 10,000 km: Grease king pins through the grease fittings. Check for steering play.
Every 40,000–50,000 km: Inspect king pin bushings for wear. Check steering knuckle for excessive play.
When steering play is detected: Inspect king pins immediately. Replace if wear is beyond specification.
At any steering system repair: Always replace king pins, bushings, bearings, and seals as a complete kit.
Standard Packaging: Anti-rust oil + VCI film + MRK brand box.
