ISUZU King Pin Kit 30×187mm OEM Standard Steering Knuckle Repair Kit ISO/TS16949 Certified for NKR NPR ELF
The ISUZU Steering Knuckle King Pin Kit, model MI-10 / KP-233, with OEM number 5-87831608-0 / 5878316080, is a precision-engineered replacement designed for ISUZU NKR, NPR, and ELF series light/medium-duty trucks. This component is a core overhaul kit for the vehicle's steering system containing king pins, bearings, bushings, seals, and all necessary mounting accessories.
The king pin is a core pivot component of the vehicle's front axle steering system, connecting the steering knuckle to the front axle I-beam. Its working principle includes:
- Steering Pivot: Serves as the rotation axis for the steering knuckle, allowing the wheel to pivot left and right for steering
- Load Bearing: Withstands the vertical load at the front of the vehicle as well as lateral and longitudinal forces during cornering
- Friction Reduction: Forms a sliding bearing interface, lubried with grease for light, responsive steering
- Precise Alignment: The king pin inclination directly affects caster angle and other alignment parameters for straight-line stability
| Symptom | Probable Cause |
|---|---|
| Loose steering; excessive steering wheel free play | Worn king pin and bushings; increased clearance |
| Front wheel shimmy (steering wobble), especially at high speeds | Worn king pin causing alignment changes |
| "Clunking" metallic noise when turning or driving over bumps | Severely worn king pin/bushings or loss of lubriion |
| Uneven tire wear (excessive inner or outer edge wear) | Worn king pin causing wheel misalignment |
| Visual inspection shows torn dust boot or grease leakage | Worn/damaged dust boot; debris contamination accelerating wear |
