- Steering noise — Worn king pin bushings create excessive clearance, causing metallic knocking or clunking sounds during steering
- Heavy or binding steering — Insufficient lubrication or seized king pin significantly increases steering effort
- Abnormal front tire wear — King pin clearance alters front wheel alignment, causing irregular or feathered tire wear
- Brake pull — Loose king pin causes steering knuckle misalignment, pulling the vehicle to one side during braking
- Excessive steering play — With the front axle raised, noticeable axial or radial play is felt when rocking the tire at 12/6 o'clock positions
