OE 56540-C9000 — Inner ball joint assembly for Hyundai / Kia

Bulk pricing is tiered: 10 pieces, 50 pieces and full-carton quantities each carry a different unit rate. Piece price also moves with packing format and whether your own brand is printed on the carton, so tell us the landed quantity you are planning.

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.

OEM means the part was produced for the vehicle maker's assembly line; aftermarket means it is made independently to the same engineering drawing. For a inner ball joint assembly the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.

Every shipment of 56540-C9000 leaves with a packing list, photo documentation and a QC report. Warranty terms are agreed per contract and reference that inspection record; claims are settled in writing against the documentation.

Build-year coverage is listed row by row in the Applications table above. Where several generations share one number, the newer rows usually carry a revised suffix — compare the last four characters before buying, since a suffix change often means a different connector or bracket.

A supersession happens when the maker revises a inner ball joint assembly and issues a new tail number. The revision normally changes a small physical detail rather than the fit. Where we know a supersession chain for 56540-C9000 we list the current reference; ask our desk for written confirmation before a large order.
