Will have to check front tire age, they are least almost 5 years old and have ~22k on them.

Bearings and axles have not been serviced yet in my ownership. Did just tighten the boot clamp on the right axle as it was slinging grease. Perhaps it had lost enough to cause an issue. If so I'll run it until I have clicking or other noticeable issue. The short steering shake does not bother me enough to warrant my looking into it too deeply. Was just curious about EODs servotronic issue in relation to mine.

As always, thanks for the info Andrew.
