I replaced my crappy broken original parts on my Ford Ranger with these. Direct replacement and lubricated port to extend service life. Installation wasn't difficult and the longest part broke the ankle. After that just go to the car dealership and rent a press for ball joints, press them out, press new ones in. READY. Put everything back together and level the car. All in all a very reliable product from Moog! I wish Ford would have supplied them from the factory! -Nigel
