Product Introduction 30Z01-01020 Steering Knuckle Bushing is the wear-resistant sleeve fitted between king pin and steering knuckle of DFL3250 front axle assembly. It forms a smooth sliding friction pair with the king pin to support axle load while allowing the knuckle to rotate flexibly for steering control. This aftermarket replacement bushing resolves stiff steering response, excessive clearance and clunking noise from the front axle, problems created by inner surface scratching, lubricant loss and outer wall deformation of worn original bushings. It stabilizes wheel rotation and reduces abnormal tire wear for regional heavy-load freight vehicles.
Product Advantages Adopts high-density alloy bushing material with excellent load capacity and wear resistance. Precision inner hole machining ensures consistent clearance with matching king pin shaft. The porous structure can store grease to maintain long-term lubrication. Each bushing undergoes dimensional tolerance inspection before shipment, simple press-fit installation and extends the service cycle of front axle steering assembly.

Q1: What operation is required after pressing new knuckle bushing?
A1: Ream the inner hole to get proper fit clearance and inject chassis grease for lubrication.
Q2: What will accelerate the wear of king pin bushing?
A2: Lack of regular greasing and muddy water entering the gap will scratch the contact surface rapidly.
Q3: Can loose bushing clearance cause steering return failure?
A3: Yes, oversized gap disturbs rotation coordination and the steering wheel may fail to return smoothly.
