King pin shimming and wear
King pin bearings let the steering knuckle pivot on the axle, and shims set the end play so the knuckle turns freely without rocking. When the bearings wear, the knuckle develops play that shows up as wander, a loose steering feel and uneven front tire wear. Shims are used to restore the correct clearance, not to fill a worn bearing, so the bearing condition should be checked first.
Measure the clearance before choosing shims and fit them in small changes. Too much shim thickness can bind the knuckle and wear the bearings faster, so the aim is smooth movement with no free play. Lubricate the bearings during assembly and check the grease fittings for proper flow.
- Play in the knuckle when the wheel is lifted
- Uneven tire wear on the front
- Wander or a loose feel at the steering wheel
