When I go over a bump, my V feels like it has something loose like the wheel is about to fall off. Wheels are 150 ft-lbs so it is not that and correct PSI. I wonder if it is the steering, hubs, struts, or the D3 sway bars. I hear it when I go over any bumps, manhole cover, pothole, driveway, turning - it just feels like something is going to get loose at any moment. Any ideas?? Sorry for the vague, non-mechanical symptoms. Thanks in advance for any help.

I doubt it has anything to do with the wheel torque. I would suggest starting at the aftermarket work done on the front end. If not done properly and to proper spec things can get loose. This can be a real safety issue and should be looked at sooner than later. Don't just get under there and start shaking things by hand. The forces at work here are much stronger than you are.
