What steering symptoms indicate a worn worm shaft in my S90?

Excessive free play in the steering wheel and a clunking feel when turning are classic signs of a worn worm shaft in your S90.

Is this a complete steering gearbox for the S90?

No, this is the internal worm shaft component. It is intended for rebuilding an existing steering gearbox for your S90.

How does a new worm shaft improve the steering feel of my S90?
