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

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

Is this a complete steering gearbox for the CLA?

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

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

It removes the worn section of the gear, eliminating the loose 'dead spot' in the center and restoring precise control for your CLA.

Does this shaft come with the necessary bearings and seals for a rebuild on my CLA?

This is the shaft only; a full rebuild kit including bearings, seals, and bushings is required to complete the job on your CLA.
