My 05
Avalon had the steering clunk when i bought it used 2 years ago i took it to a local dealer and for about $150 they greased the shaft and said it didn't need to be replaced. Never had a problem with it again.
Last month i bought my wife a 08
highlanderlimited. No clunk but since this one i believe has electric power steering and when i turn the wheel to the right there is a little noise like a motor but when i turn it to the left it is a more noticeable noise. Not loud or anything but if the radio is below like volume 5 and you are driving slow it is noticeable.
should i get it checked out? really don't want to go to the dealer and hear nothings wrong and i owe them a $100 diagnostic fee or something! But i am still under my 3 year 36k for about another month.
