That 560 I just picked up had something snap in thefront end. To me it looks like a torsion bar, but its up high and to the back of the driver's side wheel well. Connects to what I would call an upper control arm.

Obvioulsly its drivable, but not safe since breaking is compromised by a hard pull.

What is this part?
Can I replace it on my own?
Can I pick it up at most part places?
Is it a torsion bar and if so does it go all the way to the passenger side?
And how hard is it to replace!

Would love some help on this asap. I am at a restaraunt for lunch using thier computer! Need to decide if I take the car straight home or if I can manage to get to work, then home.

Thanks much!
