Humming? I've been having a "creaking" noise when steering clockwise in my car. I've already brought the car in 5 times for this issue.
The first time, they replaced a "clock spring."
The second time lubricated some rubber boot.
The third time they thought it was a rack and pinion gear, so they ordered one. The fourth time they replaced the rack and pinion gear.
This time they believe they've pinpointed it to the U-joints in the steering column. They say they've replaced them. I'm picking it up later today, so we'll see if it's finally fixed.
One of many minor issues I've had with my 04 ES. I've been at the dealership far too often. All of the service consultants know me by name.
