FAQ

1. How do I confirm this king pin kit fits my Isuzu NLR or NMR?

Verify the OEM part number on your existing king pin assembly. This kit matches part number 5-87832400-0. Additionally, measure the king pin diameter (typically 25mm for N-series) and the thrust bearing inner diameter. If your vehicle uses a different part number (e.g., 5-87832300-0), consult your service manual or contact our technical support for cross-reference assistance.

2. What is the recommended installation procedure for this kit?

Installation involves removing the steering knuckle, pressing out the old king pin and bushings, and pressing in the new components. Use a suitable press tool to avoid damaging the thrust bearing. Torque the king pin lock nut to manufacturer specifications (typically 180-220 Nm for N-series). After installation, check steering free play and adjust as needed. We recommend professional installation by a certified mechanic.

3. How often should the king pin kit be replaced in commercial use?

In heavy-duty applications like excavators or delivery trucks, inspect the king pin kit every 50,000 km or 12 months. Signs of wear include excessive steering play, uneven tire wear, or knocking sounds during turns. Replace the kit immediately if any component shows pitting, scoring, or deformation. Regular lubrication of the thrust bearing (every 10,000 km) can extend service life up to 100,000 km under normal conditions.
