We have owned a T4R for 5 years. Recently i have noticed that the steering is feeling vauge on cornering. The car is a leaf spring type. I have noticed that the steering arm that runs along the leaf spring to the steering box has a spring in the end. When I turn the steering wheel, this spring compresses before the wheels start to turn. My guess is that this is happening while cornering. I have replaced the Moly lube in the front hubs but this made no difference. Could the spring in the link be broken or old and week? Over inflating the tyers made a difference.
