By lowering the suspension you change the position of the ball joint and make it run in a different location than it had for however many miles the vehicle was driven at stock height. In some cases this can cause the joint to wear at a faster rate than normal.
i would have to agree with that statement, makes perfect sense to me.
but it would simply be speculation if anyone stated that lowering an EX, Xinches would cause them to fail around Xmiles.
there are so many variables, that it would be pretty difficult to even somewhat accurately predict the life of a ball joint on a lowered EX(or any other vehicle for that matter).
remember, we all have our own driving style, drive on different roads, carry different loads, run different shocks, and have various EX models, driven by people we don't know(if bought used), lowered at different spots on the odometer, etc, etc, etc.
if you're worried about your ball joints failing prematurely, remember that the next time you feel the urge to do something you know will make your EX bounce like a $20ho. lol, seriously just take it easy and don't abuse your EX. any more than necessary, of course
