All, Have a 99 RX300 AWD and it does not like the cold weather. Main concern is a terrible grinding coming from under the wheel well while making a steep angle left or right turn. It makes the noise under the left wheel well when making a steep angle (nose down) turn to the right and vice versa. It is as if the suspension is allowing the car to bottom out. It has 49,000 miles on it. I see in Alldata there is something indicating a symptom and canadiandriver has it too. I would almost think it needs strut replacement. Can that be true on a 1999 w/under 50K? http://www.canadiandriver.com/articles/jc/99-02rx300_a.htm http://www.alldata.com/TSB/74/99740513.html Chris
