just curious if anyone can tell me whether or not the ls has a whole control arm module or can I just replace the ball joints and a ballpark number on how much to repair? help?:mad:

The ball joint is included with the knuckle, not the control arm. I ordered the knuckle from teamfordparts.com. I believe labor to have it installed is about $100 or so. To have it replaced at the stealership with them providing the parts , I got quoted for about $500...a little pricey! Good luck!

I had this issue as well, but could not find ANY car parts store/dealer who could locate just a ball-joint.

Had to buy both lower control arms (which include a new ball joint) from Ford.

Just had the knuckle and the lower control arm replaced last week at the dealership. Was $1082 for parts and labor. It was so bad that the guy at the shop wouldn't drive it out f the parking lot. Guess it was worth it.
