Accelerated front tire edge wear, steering wheel shimmy, and dangerous axle play resulting from worn king pins and king pin bushings can severely compromise your heavy-duty fleet’s safety and operational efficiency.
Technical & Material Highlights
- Induction Hardened Pins: High-frequency induction heat treatment for superior wear resistance.
- Precision Bushings: High-lead bronze or composite bushings ensuring smooth rotation under extreme loads.
- Complete Overhaul Kit: Includes high-precision pins, durable bushings, thrust bearings, shims, and heavy-duty seals.
Troubleshooting Steps
- Jack up front axle and place a dial indicator on the wheel rim to accurately measure play.
- Check top/bottom movement: If vertical or horizontal play exceeds manufacturer specification, immediately replace with a premium king pin assembly.
- Inspect grease channels: Ensure old, hardened grease is thoroughly flushed out during the new kit installation to maintain optimal lubrication.
For additional front-axle stability and suspension performance, consider routinely checking your truck suspension parts and replace worn components proactively.
