Yeap, as StephenVA says, those are the bolts and you can reuse apparently. I am a guy that thinks once a metal bolt is stretched, its weaker than it needs to be and if I am honest I was a bit forceful with the removal of these bolts so they where pretty buggered. I have fitted new ones and they are much easier as I haven't taken all the edges off the bolts and nice and easy to tighten to correct torque.

Good luck, hope it solves the problem.

Unfortunately for me it appears the problem is not the bolts holding the reinforcement plate :( . All bolts tight and no obvious signs that they had been removed in past so I left them alone - also no indications of wear or movement around any of the bolts. Steering seems fine - smooth, vehicle tracks straight and tires wearing evenly. I'll have to have the suspension inspected unless anyone has any other ideas?

Perhaps sway bar links loose/worn. As a matter of fact if they serviced the front airbags/struts they would have had to remove/detach the swaybar links. I ve seen these items clunk on a front suspension especially if they were not tightened back up correctly.

I've re-used mine quite a few times. I didn't tighten them to 45ft-lb either. I just go straight to 100ft-lb and call it a day. Never had an issue.

For those who tightened them, did it wheels on ground or car lifted wheels hanging?
I have the same clonking, but the bolts seems as tight as possible.
Read somewhere that you should loose the bolts a bit to allow the metal plate to replace itself, then tighten back.
