What This Part Helps Address

• Front-end looseness or play from a worn lower control arm
• Clunking or knocking noises from the front suspension
• Uneven tire wear related to suspension geometry wear
• Steering instability or wandering on Volvo XC60 models
• Ball joint wear at the front left lower suspension point

Installation Notes and Tips

Install RK621743 on the front left lower position only for the listed Volvo XC60 model years. Verify alignment after replacement, since control arm service can affect camber and toe settings. Inspect adjacent suspension components, including bushings, ball joints, and mounting points, before final assembly. Confirm that the bolt-in ball joint and pinch-style stud match the vehicle’s original configuration before installation.
