OE 51760-3K000 — Lower arm ball joint assembly for Hyundai / Kia

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 lower arm ball joint assembly the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.

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.

The Related OE References table above lists the alternates we see most often in trade inquiries. Cross-references work because the engineering envelope is shared across the suspension, steering & brake family — always confirm dimensions and connector layout before you swap.

Noise normally traces to worn internal surfaces, a loose mount, a dry bearing or contact with a neighbouring part. Isolate it by reproducing the sound at a fixed speed, then compare against the reference photo for 51760-3K000 to confirm the right replacement.

Start from the code cast or printed on the part you are removing — that is the authoritative source. If it is illegible, use the Applications table on the closest suspension, steering & brake reference and narrow by build year. Send photos and we will cross-check the number for you.

Four variables explain most of the spread: material grade, whether the goods are new production or clearance stock, packing format, and whether the quote is ex-works or landed. Ask for the material certificate alongside the price — that is what makes a comparison like-for-like.
