• Reduces Tire Wear: Prevents uneven tire wear caused by loose king pins
• Direct Replacement: Engineered to match OE dimensions - proper installation may require reaming
• Extended Service Life: With proper lubriion, this kit can last hundreds of thousands of miles
• Safety Critical: Ensures predictable steering and safe vehicle control

Hyundai Vehicle Models:

• Hyundai HD65 (light/medium-duty truck)
• Hyundai HD2.5t (light-duty truck)
• May also fit other Hyundai HD series with similar front axle - verify

1. Safely lift and support vehicle - remove front wheels and brake components
2. Remove steering knuckle - disconnect tie rod, drag link, and steering arm
3. Press out old king pins - use a hydraulic press. Remove old bushings from axle beam
4. Inspect axle beam bores - check for ovality or damage. Clean thoroughly
5. Install new bushings - press into axle beam (upper and lower). Ensure oil holes align
6. Ream bushings to size (if required) - using a precision reamer to achieve correct king pin clearance (0.001-0.003 inches)
7. Lubrie king pin - apply high-quality chassis grease
8. Assemble thrust bearing - place on lower or upper side as per OE orientation
9. Insert king pin - tap into place using brass drift. Install lock pins or retaining bolts
10. Check end play - use dial indior to measure vertical movement (≤ 0.005 inches). Adjust with shims if necessary
11. Reassemble steering knuckle, seals, caps - install dust caps and grease fittings
12. Grease thoroughly - pump grease until fresh grease appears from all seals
13. Reinstall wheels and brake components - torque lug nuts and fasteners
14. Road test - check for smooth steering, no binding, no play. Re-torque after 500 km
