I am looking for a DIY to replace pneumatic spings.. I cannot find..... can you help me?



Assuming you are talking about the trunk lid supports and that they are the same as in '97 Boxster, here is a DIY I had written up a few years ago:

Looking at the ends of the hydraulic arms from their backside (i.e., not the side that presses on to the metal balls), you will see a thin, black curved spring steel strap that wraps around the rounded, curved part of the arm end (one on each side of each hydraulic cylinder). You will also notice that there is a groove that starts at the outboard end of each of the spring steel straps and goes on a diagonal away from the steel strap.

Insert a small, THIN flat bladed screw driver under the center of the spring steel strap STARTING FROM THE SIDE CLOSEST TO THE CENTER OF THE HYDRAULIC ARM (We will call that the inboard side). Then, while pressing in, lever the black spring steel strap upwards so that it sort of rotates around and ends up being guided into the diagonal slots. Be careful that the small steel strap doesn't get airborne because it is spring steel and it can pop out with some force.

Continue to pry off the steel strap and once it's out, the hydraulic arm will easily pull away from steel ball.

Installation is the opposite. Press in the steel strap while rotating it around inboard into position so that it ends up flat across the back of each rounded, curved part on the end of each arm.

Check to make sure that each spring strap is firmly seated and try to separate the ball from its socket by pulling it apart. It should not pull apart if the straps are seated properly.

Regards, Maurice.

thanks Maurice,

url of this DIY? I remenber there were pics


When I wrote it up, it was without pics. I think I first posted it on PPBB.com about three years ago.

If you follow the words carefully, you will be able to get them off and on. It will make more sense once you look closely at the ends of the struts and the little metal strap that locks them on.

Regards, Maurice.
