Given the prices of 7 yr old E320s, I do not feel like spending a lot of money on this as I can manouvre the car OK, its just that the steering is a little stiff. |
After you change out the fluid if it's still stiff you can put the front end up on jackstands and then start it and turn the wheel back and forth. That sometimes will help you find binding spots during the turning that can help a diagnosis. The fact that cold or hot is the same leans away from the rack, unless of course it was that way a year ago but the wife didn't let you know.
