Hi all. 2013 200 series with 182k miles here. I have been experiencing a vibration in my steering wheel. The vibration is more of a hand numbing vibration than a shake. It is very pronounced at highway speeds. In addition I am also experiencing a lot of wandering and loose steering at highway speeds. Occasionally, the steering wheel will shake with braking (especially when the cruise control does the braking) but this is not all the time and seems pretty random. Because I can't always make the steering wheel shake during braking, I think that the brakes are OK and look to have plenty of life left on the pads. I have replaced UCA and ball joints, LCA and ball joints and outer tie rods as well a rebuild on bp51 shocks in the past year, so kinda rules those out. In addition, I have new tires as of a few months ago which have been road force balanced twice and 3 different alignments done. Things have gotten better through all of this but still have the hand numbing vibration, wandering loose steering, and occasional steering wheel shake during braking. Any help or similar experiences would be greatly appreciated!
