My steering wheel is showing the following symptoms: *settles off-centre (5-10 degrees to the left) *shakes about 4 times a second at 110km/h *needs to be at 5 degrees to the right for the car to go straight While the car is moving (accelerating or cruising) if I glt go of the steering wheel it re-settles itself to the left. This happens when the road is slightly lower on the left, flat, or slightly lower on the right. When the road is much lower on the right, the steering wheel re-settles itself to the right. At 100km/h there is no steering wheel shake. At 110km/h it shakes. It occurs at a frequency of about 4 times a second and the steering resistance appears to drop about the centre position. Step 1. Dealer performed wheel alignment and no change. Step 2. I then got a quiet rattling sound* from steering column when road is bumpy. Step 3. Dealer replaced steering column for $650 and no change. Step 4. Are there any Aurion expert mechanics in Sydney? *This noise appears a few years ago and was gone after they replaced intermediate steering shaft under warranty.
