3-3.5 Ton Forklift Steering Knuckle Main Pin Repair Kit Forklift Truck Parts

Steering Knuckle Main Pin Repair Kit for 3-3.5T Forklift

The main pin repair kit is a complete kingpin bearing set for the steering knuckle pivot on 3-3.5 ton forklifts — including the hardened main pin (kingpin), upper and lower bushings or needle bearings, thrust washers, seals, and retaining hardware. This main pin repair kit restores the critical pivot joint where the steering knuckle rotates around the kingpin axis on the rear axle beam. A worn main pin repair kit produces the classic “wheel wobble” symptom: jack up the rear wheel and rock it top-to-bottom — any play indicates the kingpin bushings or bearings are worn beyond the service limit, requiring immediate replacement.

Built with a hardened and ground kingpin shaft, precision-machined bushings or bearings, and hardened thrust washers, this main pin repair kit eliminates the pivot play that causes steering wander, uneven tire wear, and a metallic knock over uneven surfaces. Always replace both sides simultaneously — one new kit and one worn kit create asymmetric steering friction that pulls the forklift to one side.
