Introduction

This Front Axle Thrust Bearing WG4005415308 is a genuine OEM chassis rotating part specially manufactured for SINOTRUK HOWO heavy-duty tractors, dump trucks and cargo trucks. Installed on the front axle steering knuckle, it bears axial thrust load while the vehicle is turning and running on bumpy roads.

As a core friction-reducing component of the front steering system, the thrust bearing supports the weight of the front axle, reduces rotational friction between the knuckle and axle beam, and ensures flexible and smooth steering operation. It effectively solves common problems such as stiff steering, noisy turning and front-end shaking caused by worn bearings. With high-precision steel body and durable grease seal structure, it adapts to heavy-load, dusty and harsh mining and logistics working conditions, serving as a fast-moving replacement part in the global heavy truck aftermarket.

Key Features

✅️Original OEM Standard WG4005415308

Strictly follows factory outer diameter, height, hole size and installation parameters. 100% direct fit for SINOTRUK HOWO front axle, no modification needed during replacement.

✅️Reduce Steering Resistance Effectively

High-precision rolling structure greatly lowers friction during wheel rotation and steering, making steering lighter and more flexible, improving driving comfort and control accuracy.
