555 SB4942 — JOINT ASSY, SUSPENSION
Overview
Lower ball joint 555 SB4942 connects the front lower suspension control arm to the steering knuckle, enabling pivot movement during steering and wheel travel. Manufactured in Japan by Sankei Industry, the main housing features cold-forged carbon steel construction paired with an induction-hardened ball stud to resist high impact forces and friction wear. The supplied fitting kit includes a chloroprene rubber dust boot, retaining circlip, and mounting nut. Key dimensions: housing press-fit outer diameter 43.2 mm, ball stud thread M12x1.25, taper diameter 18 mm. OEM cross-references: Mitsubishi MR403419, MR403420, 4013A087, 4013A090, MB831037. Pre-filled with synthetic grease suitable for operating temperatures between -40 °C and +120 °C.
Vehicle application list includes Mitsubishi Lancer IX 2003–2008, Outlander I 2001–2006, Airtrek 2001–2005, and Space Runner 1999–2002 models. Replacement is required when detecting axial or radial play inside the socket mechanism, torn rubber dust covers, lubricant loss, or knocking sounds during front suspension compression over rough road surfaces. This replacement part press-fits into both left and right lower front suspension track control arms. Installing a new joint restores precise steering control, tracking stability, and factory suspension kinematics.
