Q3

How do I replace the suspension struts on a 2011-2018 Mercedes B-Class?

To replace suspension struts, first, safely lift the vehicle and remove the wheel. Disconnect the sway bar link and brake line bracket. Unbolt the strut from the steering knuckle and remove the upper mounting bolts inside the engine bay. Install the new strut in reverse order, ensuring all bolts are torqued to manufacturer specifications. Perform a wheel alignment after replacement.

Q4

What are common suspension issues in the 2011-2018 Mercedes B-Class?

Common issues include worn struts or shocks, leading to a bumpy ride, uneven tire wear, or poor handling. Noises like clunking or squeaking may indicate worn bushings or ball joints. Leaking fluid from shocks or struts is another sign of failure. Diagnose by inspecting components for wear, damage, or leaks, and replace as necessary.

Q5

How can I optimize the suspension performance of my 2011-2018 Mercedes B-Class?

To optimize suspension performance, use high-quality OEM or aftermarket components like performance shocks or lowering springs. Ensure proper installation and alignment.
