i voluntered to replace the ball joints on my bosses' Durango. what is the easiest way to do this? first glance looks like i have to remove the caliper, wheel bearing, and half shaft. is it possible to unbolt the half shaft from the diff. and pop the spindle form the ball joints and then pull them? does anyone know off hand what size the half shaft nut is? im guessing maybe 32mm. bad thing as well, is it seems like it needs TREs as well.
