35mm Diameter 195mm Length King Pin Kit ASTM 1045/5140 Steel for Mitsubishi Fuso Canter FK417

The King Pin Kit, Model KP548 / MM-70, with OEM number MC998681 (cross-reference 1-87830-064-0, MC808090, MC828684, MK996662), is a verified direct-fit replacement for Mitsubishi Fuso Canter FK417 series medium/heavy-duty trucks. This king pin kit is a complete repair solution for front axle steering knuckle maintenance, including king pins, bearings, bushings, shims, and seals — widely used in Mitsubishi Fuso Canter FK417, FK617, FH21H, FK727, and Fighter series trucks.

The king pin is the core pivot component of the front axle steering system, connecting the axle beam to the steering knuckle, allowing the wheels to pivot left and right for steering. This king pin kit includes the following components:

• King Pin — Precision-machined pivot pin, bearing vertical front axle loads and steering lateral forces
• Bearings / Bushings — Reduce friction between the king pin and steering knuckle for light steering effort
• Shims / Seals — Adjust axial clearance and prevent grease leakage and contaminant ingress

When the king pin and associated bearings/bushings wear out, the steering system develops play and vibration. This kit provides all necessary components for a complete steering knuckle overhaul.

• Loose Steering / Excessive Play — Increased steering wheel free play; delayed steering response (excessive clearance from worn king pin and bushings)
• Front Wheel Wobble / Vibration — Noticeable wheel oscillation while driving, especially on rough roads (worn king pin bearings)
• Heavy Steering — Steering wheel becomes significantly heavier (poor lubrication or binding bushings)
• Uneven Tire Wear — Feathering or irregular wear on front tires (wheel misalignment due to loose king pin)
• Brake Pull — Vehicle pulls to one side during braking (misaligned steering geometry from king pin wear)
• Clunking Noises — Metallic knocking sounds from front axle while driving or turning (severe king pin or bearing wear)

1. Safety Prep — Park on level ground, chock wheels, lift and support front axle
2. Remove Front Wheel — Remove front wheel tire and hub assembly
3. Remove Steering Knuckle — Remove tie rod end, brake caliper, and other components; remove steering knuckle from axle beam
4. Press Out Old King Pin — Use special press tools to press old king pin out of the knuckle
5. Clean Mounting Holes — Thoroughly clean king pin mounting holes in knuckle and axle beam
6. Inspect Mounting Holes — Check for scoring, wear, or deformation
7. Install New Bushings — Use special press tools to press new bushings into knuckle (do not hammer)
8. Install New King Pin — Insert new king pin through knuckle and axle beam; ensure smooth fit
9. Install Bearings & Shims — Install new bearings and adjustment shims; set king pin axial clearance to specification
10. Grease — Inject sufficient high-quality grease through grease fittings
11. Install Steering Knuckle — Reinstall knuckle assembly onto axle beam; torque mounting bolts to specification
12. Reinstall Components — Reinstall brake caliper, tie rod end, and other components
13. Wheel Alignment — Wheel alignment is mandatory — adjust toe and camber angles to specification
14. Road Test — Perform road test — confirm smooth steering, no pulling, no abnormal noise
