Detailed Description

This Dorman suspension ball joint, part number 539-804, is engineered for front lower suspension service where a worn joint can affect steering response, alignment stability, and tire wear. It uses a steel body, bolt-on mounting, and a pinch-style stud to match the specified OE-style application. This part cross-references MOOG Chassis Products K500319 for the same application. For shoppers searching for a front lower ball joint for 2014-2016 Kia Sportage, 2014-2015 Hyundai Tucson, or 2015 Hyundai ix35, Dorman 539-804 provides a direct-fit replacement option.

What It Helps Fix

• Front-end clunking or popping from a worn lower ball joint
• Excessive suspension play at the front lower control arm
• Uneven tire wear caused by loose suspension geometry
• Steering wander or reduced directional stability
• Inspection failures related to ball joint wear

Installation Notes and Tips

Verify vehicle fitment by year, make, model, and front lower position before installation. The bolt-on design uses 3 mounting holes and a 12 mm mounting hole diameter, with included castle nut and cotter pin for the stud connection. Because this is a non-greaseable assembly, no grease fitting service is required after installation. Professional alignment is recommended after replacing a front lower ball joint on the Kia Sportage, Hyundai Tucson, or Hyundai ix35.
