Installation Guidelines
IMPORTANT: King pin replacement is a safety-critical repair. Professional installation with correct tooling is strongly recommended. A hammer should never be used — it can deform the king pin or damage surrounding components.
Lift and secure the vehicle on a level surface
Remove wheels, brake calipers, tie rod ends, and drag link as required
Remove the old king pin using a hydraulic press or specialized removal tool
Clean and inspect the axle beam bore and steering knuckle bore
Install new bushings using proper driver tools
Insert the new king pin — ensure centered and seated flat
Torque specification: Consult NISSAN PK-series workshop manual for exact values
Check vertical play and verify within OEM specification
Lubricate through grease nipples with high-quality chassis grease
Maintenance Schedule
Lubrication: Grease king pins at every chassis lubrication interval (typically 10,000–15,000 km)
Inspection: Check for vertical play, steering looseness, and uneven tire wear at every major service
Full replacement interval: Rated for 80,000–150,000 km depending on operating conditions
Alignment check: Perform front-end alignment after king pin replacement
