Are you getting tired of having your front or rear trunk lids fall on your head? It's probably time to replace your hood shocks. These are among the most disposable of parts on the W210 Mercedes. They will fail - it's just a matter of when. Replacing them is an easy task, however one that is made easier with small hands that manipulate tiny pieces. With a little bit of patience, you can replace your hood shocks in about 5 minutes.

The front hood uses gas-pressurized shocks that hold up its weight. Start by lifting up the front hood, and securing it by putting the hood into the service position. This is done by pressing the catch release on the left side hood hinge looking towards the rear of the car with the hood open. You'll need to pull the hood down slightly to press the catch in. Once pressed, push the hood up as far as it will go. The catch will engage and hold the hood up while you change the shocks one side at a time.

Starting with the right side, place a rag or shop towel over the sheet metal to protect the paintwork. There is a small clip that holds the the end of the shock to the ball pivot, you will need to loosen or release that clip by using a small screwdriver to pry it off the pivot. Then use a large flat blade screwdriver to pry the upper connection point for the hood shock off the ball pivot. Next, pry the shock off the lower ball pivot. Once the hood shock is removed, clean the ball pivots and put a dab of white moly grease on each of them.

Replace the old shock in the same place and orientation that the old was in. For reference, the smaller diameter rod of the hood shock points downward. The thicker diameter rod faces upward. Line up the lower connection point with the ball pivot and give it a good push with the palm of your hand. It should just pop into place. Rotate the hood shock up into position with the upper ball pivot and pop it on like the bottom one. You may need to move the hood upwards slightly for the holes of the new hood shock to line up with the ball pivots. Don't try to compress the new hood shocks. You will find it incredibly difficult.

The rear hatch shocks are very similar in their replacement process. The only difference is that the orientation is reversed. The smaller diameter rod faces the top while the thicker faces the bottom.

Hood shocks are a common wear item that are easily replaced in a matter of minutes.

Use a screwdriver or small pry bar to pry the upper hood shock connection off the upper pivot ball.

Use a screwdriver or small pry bar to pry the upper hood shock connection off the upper pivot ball. I'd also recommend placing a shop rag in-between the screwdriver and the side of the hood to protect the paint. In this picture I've left the rag out to make the picture a bit clearer.

Place a towel or shop rag over the sheet metal to protect the paint and use a large flat blade screwdriver to pry the lower hood shock off the ball pivot.

Place a dab of white moly grease on the both ball pivots prior to installing the new hood shock (green arrow).

I would grab a repair manual. It will have the procedure, special tools and torque specs.

John Comments: I purchased hood shocks from you but when fully extended they're too long to fit the hood. I can't lift the hood enough to make them fit. Part number 210-880-04-29 624. What am I doing wrong?

Phuong Comments: I figured it out. Some of our Mercedes come with 2 struts, and one of the struts the one that is attached to the red button that allows to be put in service mode is shorter than the other one. I bought my struts from Tuff Support. And they sent equal length struts.

Phuong Comments: I just change my lift support to my w209. Now it won't let me open it to the service position. Do you know what I did wrong?

  Followup from the Pelican Staff: Maybe to the wrong part number? I would double check, the strut may be too short. - Nick at Pelican Parts
