Ball Joint

A ball joint is the spherical bearing that links the control arm to the steering knuckle. It carries vertical wheel load while letting the suspension travel up and down and the wheels steer left and right — every turn you make passes through it.
— Knocking or clunking over bumps and rough roads
— A dull pop when turning the steering wheel at low speed
— Uneven tyre wear — often on the inner or outer edge
— Steering that feels loose, wanders, or pulls to one side

Hetian ball joints use cold-forged, induction-hardened studs running in pre-loaded, PTFE-lined housings, sealed with high-temperature EPDM dust boots. Every design is verified in our CNAS-accredited laboratory — radial and axial load, torque retention and salt-spray corrosion testing — under IATF 16949 production control.
Range: 348 SKUs · 2,703 OE cross-references — marked as position 1 on the diagram below. Hetian manufactures 348 ball joint SKUs with OE cross-references, forged and bonded in-house under IATF 16949.
