Steering Knuckle Bearing 38x65x20mm (fits JCB) - TIMKEN 907/05800
High-quality steering knuckle bearing 38×65×20 mm by TIMKEN — the world's leading manufacturer of rolling bearings for industry and construction machinery. The bearing is fitted in the steering knuckle pivot of the front and rear axle, where it provides smooth, play-free rotation of the steering knuckle and precise wheel guidance during machine cornering. This is a safety-critical component — a worn or damaged bearing shows up as play, knocking or steering wheel vibration, and uneven tyre wear. TIMKEN brand guarantees durability and reliability confirmed by decades of proven performance in JCB construction machinery.

Workshop Technical Tip: A worn steering knuckle bearing shows up as noticeable lateral wheel play when pushed, metallic grating or knocking during cornering, steering wheel vibration over rough ground and uneven tyre wear (excessive edge wear). Always replace knuckle bearings in pairs — upper and lower at the same time. The bearing must be pressed in using a press or a correct-size driver — never by direct hammer impact. Set the spindle nut preload to the manufacturer's torque specification — under-tightened means play, over-tightened means overheating and premature failure. After assembly, always grease through the nipples and check wheel alignment (toe-in/toe-out).
