Do you have to replace the ball joints as well when replacing the lower forward control arms? If so what size ball joints are needed for a 2010 a4 Quattro prestige sline
Thanks for your inquiry. It's usually a good idea to change the ball joints along with the control arms, but they can be re-used if they are in good shape. If you are not sure if you need new ball joints we suggest taking your vehicle to a nearby reputable shop. Thanks!
