I have a creaking noise from the steering on my 56 GTI, been there for a year since I had the car. Doesn't seem to be getting any worse although I heard a knock recently which appears by rocking the steering back and forward so could be a track rod end away. I worry that the steering rack is giving up the ghost with the creaking but it does not seem to be deteriorating and certainly doesn't grind at full left or right locks etc.
Interestingly, one poster complained about lumpy power steering when stationary or moving very slow and parking or changing direction quickly; I get this too that the power steering unit does not appear to be able to cope with a rapid change in direction from full lock one way to full lock the other....most bizzarre
The car goes in for a service next week and I have alterted them to my steering issues, hopefully it's a track rod end responsible for the knock and that's all it needs!
