Just tell them there's a knock, from the steering area. Mention the intermediate shaft. Await the response. Yep had my service done, and asked for the noise to be looked at... i have reported the noise for the last 4 service intervals (i get them done each 7500km) Toyota response, "There is a small amount of play in your left hand rack, its nothing to worry about" Hmm.. The noise is still there, and i cant say that im in an way happy..? My Aurion is a 2006 Sportivo sx6, and such is out of warranty. Any thoughts for aftermarket assistance... suspension company? or steering company? Thanks
