One and a half years ago, I had to replace the original 12 year old lower ball joints on my 2005 GT. It only had 42,000 miles on it at the time. I think, like a lot of things that age might be more damaging than miles.:frown: However, this is not the only S197 I know of with early failure of OEM ball joints.
The only symptom I had was shuddering (wheel shake) under medium to heavy braking pressure anywhere above 40 mph or so, before and after new pads & rotors.
I went ahead and had them replace the entire lower control arm assy on both sides because it is actually less total money than paying for ball joints and bushings and MASSIVE labor charges. It cost me just over $300.00 out the door. Separately, neither the rear bushings nor the ball joints are a piece of cake laborwise, therefore not cheap at all.
