These replacement ball joints are just what you need to ensure the safety and integrity of your vehicle's suspension and steering.

Specifications:

  • Comes as a SET of 4
    • Fits both LH (Driver Side) & RH (Passenger Side) FRONT UPPER & LOWER
  • Replaces dealer part numbers: 12475478, 12475486
  • Direct replacements
  • Built to strict quality control standards

Note: Upper ball joint alignment hole in flange must point toward the wheel when ball joint is pressed in to the arm

Worn ball joints can cause excessive front tire wear, popping or creaking in the front end, extra play in the steering system, and pose a serious safety concern. Replace loose or worn ball joints with our quality replacement.

One way to diagnose a loose, or warn ball joint, is to jack the car up, so the wheel is off of the ground, then have someone try to move the wheel in and out. While they are moving the wheel check the ball joint for play, if it is moving you probably need to replace it.

Our steering and suspension components are pre-greased and sealed for long life and do not require the extra maintenance typically required by greasable versions.

Perfect Fit
I order top and lower ball joints for 01 Yukon XL. They arrived on time for state inspection. They were a direct fit so they were easily to put on the truck. But just for future reference the upper ball joints on the Yukon and similar vehicles the upper ball joints home eventually grows bigger in size. So if you run into this problem just get the top control arm, so you don't have to put a spot weld on them to hold.
