What It Helps Address

• Front suspension looseness or play
• Clunking or knocking from the lower suspension area
• Uneven tire wear related to worn ball joint movement
• Steering wander or reduced front-end stability
• Inspection failure caused by excessive joint wear

Installation Notes and Tips

Verify the vehicle’s front lower suspension configuration before installation. The tapered stud, cotter pin hole, and castle nut design should be matched to the original mounting style, and the joint should be torqued to the vehicle manufacturer’s specifications. Because this is a bolt-in, threaded assembly, proper alignment inspection is recommended after installation on the Honda Civic or Acura ILX.
