| High Light | SAE 1045 Carbon Steel King Pin Kit ，Complete Both-Sides King Pin Kit ，50-63 HRC Hardness KP-133 MN-53 Kit | ||
This Steering Knuckle King Pin Kit is a verified direct-fit replacement for Nissan UD CM-90 trucks, with OEM numbers 40025-Z5025 / 40025Z5025 and internal codes KP-133 / MN-53. The kit is a complete both-sides assembly containing king pins, bushings, bearings, seals, shims, and lock pins, specifically engineered for Nissan UD CM-90 (1976-1980) and Condor CM-85 platforms.
The king pin is the critical pivot that connects the steering knuckle to the front axle assembly. It supports the vertical load of the vehicle's front end while allowing the wheel hub and steering components to rotate smoothly for steering. The king pin operates in conjunction with bushings and bearings, relying on a lubricant film to minimize friction and maintain precise steering return.
These symptoms indicate that king pin-to-bushing clearance has exceeded allowable limits and the kit should be replaced promptly to prevent further steering system damage.

| King Pin Dimensions | CMM measurement, tolerance control on Ø35.15*205mm |
| Surface Hardness | Rockwell hardness tester, batch sampling 50-63 HRC |
| Case Depth | Metallographic specimen method, standard 0.9-1.2mm |
| Bushing Bore Fit | Air gauge / inside micrometer, ensuring clearance with king pin meets spec |
| Material Composition | Spectrometer verification of SAE 1045 carbon steel |
| Appearance & Marking | Visual inspection, OEM number and model clearly marked |
| Outgoing Sampling | Batch sampling per AQL standard |
King pin replacement on a commercial steering axle is a heavy-duty chassis repair involving front axle disassembly and steering system reassembly. It must be performed by a qualified technician using specialized press equipment. Incorrect installation torque or fitment clearance will directly result in steering failure risk.
