I'm going to look into this .... the car has only 126k seems a bit early but who knows.... its a heavy car.
They are extremely heavy and IMO the suspension links wear out really fast. My outer tie rods and the center control arms died at 88K and trust me i drive her real careful. My friend whos garage i use to work on my car said they wore out faster due to the low profile tires and rims. Apparantly its harder on the whole suspension system. Anyways i had the similar rocking thing due to the center control arm (large busshing). I changed the whole front end suspension links....noticed the steering felt tighter as well. Id suggest doing a front end rebuild and tighten all the nuts to factory specs...that has to be done when the car is on the ground and not suspended. I believe its 75Nm for the centre arm.
