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. Lubricate 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 indicator 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
