There are two shocks that hold up the rear deck lid on your Porsche 993. These shocks will weaken over time and eventually fail. Signs that the shocks are starting to go bad are they do not hold the lid as high as they used to, the lid is getting heaver to lift and the lid settles down a little when open. The shocks are easy to replace and there is just no pride in having to hold a Porsche lid open with an old broom handle.

The shocks connect to the hinge on the deck lid and to a mount on the firewall. Once you get access to them there are very easy to change out, but be warned even if the shocks are brand new a single shock does not have the power to hold the lid up so watch your head and do not expect the single new shock to hold the lid while changing the other. While I have heard of some mechanics that change out the shocks with the blower motor in place I have not heard of anyone changing the right shock out with the airbox and lid in place.

If you are just starting to DIY on your Porsche do yourself a favor and get in the habit of moving things out of the way rather than being uncomfortable and risk dropping small parts into the engine bay.

Begin by supporting the weight of the deck lid by having a friend hold it or securely brace it so it will not fall on you while you are working.

Begin by supporting the weight of the deck lid by having a friend hold it or securely brace it so it will not fall on you while you are working. There are two shocks that hold the lid up; one on each side connected to the hinges and the mount on the firewall (red arrows). It is a tight fit replacing the left shock with the blower motor in place but almost impossible on the right side.

By removing the blower motor and airbox you give yourself all kinds of room to work.

By removing the blower motor and airbox you give yourself all kinds of room to work. You are going to be working with very small clips and at the rear there is a good chance the sound insulation will be hanging in your way. It's brittle so make the job easy on yourself and remove everything first. Please see our article on blower motor (varioram) or blower motor (non-varioram) depending on your car and airbox removal for additional information

The shocks mount to the hinge and rear mount by small retaining pins and clips (red arrows).

The shocks mount to the hinge and rear mount by small retaining pins and clips (red arrows). We are going to show you how on the left side shock but the right is the same.

You should be able to lift the edge of the clips (red arrows) with your finger nail and slide the clip out from the groove in the pin.

You should be able to lift the edge of the clips (red arrows) with your finger nail and slide the clip out from the groove in the pin. If you need to use a small flathead screwdriver be careful as it is easy to lose these clips when they come off.

Slightly raise or lower the lid until the pressure is off the pin and then slide the pin out and the shock should just drop out.

If your shocks have failed, the new ones will be longer than the old ones so be prepared to move the lid up until the new shock fits the opening.
Figure 6

If your shocks have failed, the new ones will be longer than the old ones so be prepared to move the lid up until the new shock fits the opening. I like to install the rear of the shock first as it much easier to line up the front pin than the rear. Installation is the reverse of removal.
