Step by step instructions on how to replace the front shock absorber on a 1998-2005 ML W163.

  1. Remove the wheel.
  2. Remove the fender liner. Another alternative is to open the hood and access the bolt from the top. To do this you will have to remove the intake air filter.w211_e320_e500_front_control_arm_diy_49
  3. You don’t need to raise the car. It needs to be with the wheel on the round when you do this. Once you remove the intake air housing you will see the nut as shown below. w211_e320_e500_front_control_arm_diy_51
  4. Remove the nut at the top. You will need to counter hold the shaft of the shock. w163_front_shock_ml320_ml430_ml500

    Note: The passenger side shock you can replace easily by removing the intake air filter. The driver side can be replaced by accessing it from the engine bay as well without having to remove the wheel fender liner. There is less space to access the nut at the top of the shock for the driver side but it can be done. Make sure to keep the car with the wheel on the ground when you replace your shocks.
