Hood and Trunk Strut Replacement
The hood, trunk, and doors on an Aston Martin are held in place when opened by gas struts. Unfortunately, these tend to wear out after a while - generally 5 years or so. You'll know when the struts need to be replaced because they won't be able to support the weight of whatever you're opening. That can be particularly problematic when you find out the hard way... like I did... when the trunk lid fell on my head. The hood and trunk struts are very easy to replace. Having an extra pair of hands helps - the other person can hold the hood and trunk open while you replace the struts - but you can still do this solo if needed. The door struts are a little more involved, so those are covered in another DIY guide.

New gas struts (hood or trunk)
Tiny flat-head screwdriver
About 10 minutes
The best way to go about this is to figure out the struts before you begin, and that's pretty easy to cover. You can do the below steps on your new struts before installing them to figure them out before removing the old ones from the car.
On each end of the struts are ball sockets with retaining clips. There's an open spot in the middle of the retaining clip. You can see it in this pic:
Put the tip of the tiny flat-head screwdriver into the opening, under the retaining clip.
Gently pry the retaining clip back from the ball joint. You don't need to remove it all the way. Once it pops back a bit, you're good. You can now pull the strut away from its mounting point.
Repeat Step 1 for the other end of the strut. You can now remove the strut entirely.
On your new strut, make sure the retaining clip is popped out so the ball socket can easily slip over the mounting point. Put the strut in place, then push the clip in to secure the strut to the mounting point. Repeat for the other end of the strut.
Repeat the process for the rest of the struts that you're replacing.
