Shimmy/Jostling noise when turning sometimes
 

Removed, will post in the correct forum.

do you have any other issues with steering? the connector for the rack is a known issue to some cars: https://www.rx8club.com/series-i-trouble-shooting-95/power-steering-failure-107481/ long thread but something to look at

Also, tired tread, wheel balance, brakes.. these have all been checked?
