It is built from steel with a casting\/forged control arm design and includes the ball joint already installed, along with rubber bushings and mounting hardware. The pre-greased construction and bolt-in ball joint mounting help simplify service while maintaining the intended suspension geometry. This part number 521-276 is a direct-fit replacement for select Honda Passport, Isuzu Pickup, Isuzu Rodeo, and Isuzu Amigo applications.\u003c\/p\u003e\u003cp\u003eDorman designs this assembly as an OE-style replacement for vehicles that need a complete upper control arm solution rather than a separate arm and joint service. The threaded ball joint stud, 14 mm ball joint thread diameter, and 12.3 mm mounting hole diameter support proper installation on the listed applications. This part cross-references Monroe Shocks \u0026amp; Struts (e.g., RK621389) for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Repair Issues\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eExcessive front-end looseness or wandering\u003c\/li\u003e\n\u003cli\u003eUneven tire wear caused by worn suspension geometry\u003c\/li\u003e\n\u003cli\u003eClunking or knocking from worn bushings or ball joint wear\u003c\/li\u003e\n\u003cli\u003eReduced steering stability during braking or cornering\u003c\/li\u003e\n\u003cli\u003eService needs where the control arm and ball joint are replaced together\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify the front right upper fitment before installation on the listed Honda Passport, Isuzu Pickup, Isuzu Rodeo, or Isuzu Amigo applications.
