Hi all,
Been tinkering the past few weeks and found the gas struts on the engine lid of my 8 year old 991, were beginning to weaken. After the third time of it coming down on my hand, I got cheesed off and decided to order a set.
I know most owners of the modern 911s don't tend to work on their own cars BUT it's a VERY SIMPLE fix, so for the sake of anyone who fancies some easy DIY rather than paying a dealer, I thought I'd write it up.
The OEM struts are made by Stabilus - Part No: 991 512 551 00. Ejection Force: 130 Newtons. Length: 168mm.
As my car's under the extended warranty, I went original at £24.25ea - crazy I know because you can buy other brands at prices from £10ea! Bought mine from Design911, who were very prompt and I had them within 24hrs.

Tools
Small flat bladed screwdriver, large flat bladed screwdriver, some kitchen roll, a couple of cloths.
Difficulty
Novice - as easy as it comes.
Here we go
1: Open the engine lid - it's very hard to do it otherwise :lol:
2: Place some cloths around the base of the hinge and fans - whilst unlikely, this is to prevent the possibility that any parts (such as a clip) will fall into the engine bay.
3: Holding the lid up with your left hand, insert the end of the small screwdriver beneath the edge of the metal clip on the upper end of the strut (the clip holds the end of the strut onto the ball head) and lever it up, against the plastic, in order to lift the clip out of the plastic. Once the clip's moved out slightly, you can use the large screwdriver to lift it further
You don't need it to come out completely, just lifted away from the plastic head.
4: Repeat the same procedure on the bottom clip.
5: Once the clips have been lifted, you'll be able to grasp the top/bottom of the strut and pull it away from the ball fixings.
6: Using some kitchen paper, clean the ball fixings of any dirt.
7: The new parts usually come with a small amount of grease inside the ends but here I've added a little Teflon grease.
8: Noting from the other (existing part) which end is up and down, simply pull the plastic end cups of the new struts onto the balls. Being greased they should pull on quite easily but if not, just tease out the metal clips a little - but remember to push them home before you finish up.
and that's it - job done and no need to pay ££s to a dealer for a simple job!
Hope that helps
