Before installation, a standard check of tightness, play, and the condition of boots and tie rod ends is recommended, as well as performing a wheel alignment after installation.

When selecting a steering rack for a specific ML W164 or GL X164 version, it is worth paying attention to:

• compatibility with the power steering system used in the vehicle,
• type of tie rods and steering ends used,
• proper fitment to the steering column.

Benefits of using an original steering rack

Using an original steering rack in a Mercedes ML or GL allows for maintaining the vehicle's factory driving characteristics. This is particularly important in heavier SUVs, where the steering system works under greater load, and steering precision affects safety and driving comfort.
