“With the Jeep Grand Cherokee L's new setup, the ball joint was moved to a virtual point. In the past, the pivot point was inside the vehicle, between the wheels. Placing the virtual ball outside the wheels gives the vehicle more lateral stability.”
"By moving the virtual ball more outboard, the vehicle is less sensitive to varying road inputs and vibrations to the driver, also providing additional stability and on center steering performance,"
Quadra-lift has a different steering knuckle but the design looks the same. Parts catalog isn’t detailed enough to see if clearances are any different.
