The king pin repair kit for heavy-duty trucks is a critical maintenance component designed to restore the functionality and safety of the steering knuckle assembly. Here are its primary functions:
The king pin (or steering knuckle pin) serves as the pivot point between the front axle and the steering knuckle, allowing smooth wheel rotation during turns.
A worn king pin can cause loose steering, wheel misalignment, and unstable handling. The repair kit restores precise movement.
The kit includes bushings, bearings, and seals that minimize metal-to-metal friction between moving parts.
Proper lubrication (via included grease fittings) extends component lifespan.
Over time, king pins and their bushings wear out, leading to steering wheel wobble or shimmy.
The repair kit tightens the assembly, eliminating dangerous free play.
A faulty king pin causes uneven tire wear (e.g., cupping or scalloping) due to misalignment.
It also reduces stress on tie rods, ball joints, and wheel bearings.
A well-maintained king pin ensures stable steering response, critical for heavy loads.
Prevents sudden failures that could lead to loss of control or accidents.
King pin (new replacement pin)
Bronze or polymer bushings (for smooth rotation)
Thrust bearings/washers (to handle axial loads)
Seals & grease fittings (to retain lubrication)
Locking bolts/nuts (for secure fastening)
Excessive steering free play
Grinding/noise when turning
