FAQ

Q1: What failures will be caused by worn Howo Kingpin?

Common symptoms include loose steering, vehicle deviation during driving, abnormal noise from the front axle, uneven tire wear and heavy steering. Timely replacement avoids damage to steering knuckle and front axle housing.

Q2: Can I place small trial orders for Howo Kingpin repair kits?

Trial orders are supported. Please confirm your front axle model before ordering to select the correct kingpin specification.

Q3:What accessories are included in the complete Howo Kingpin repair kit?

The full repair kit includes kingpin, copper bush, thrust washer, oil seal, O-ring and grease fitting, covering all parts needed for front axle overhaul.

Q4:How long is the service life of a genuine Howo Kingpin?

Under normal road and standard load conditions, the genuine OEM Howo Kingpin can serve 2–3 years or 150,000–200,000 kilometers. For mining, bumpy roads and frequent steering scenarios, regular inspection every 80,000 kilometers is recommended to prevent steering failure.

Q5:What is the difference between OEM and aftermarket Howo Kingpin?

Genuine OEM Howo Kingpin adopts integral alloy steel forging and high-temperature quenching treatment, with precise tolerance and strong deformation resistance. Aftermarket products are prone to wear, bending and loose steering clearance, which easily cause tire deviation and safety risks.
