I bought a cheap pair of pneumatic cylinders that support the XC90 hatch. The hatch motion was jerky - not smooth like the factory cylinders. As a result, one of the pivots on the hatch end of the cylinder pulled out of the hatch. The pivot looks like a wood screw with a ball where the cylinder attaches. It threads into a material that looks like plastic in the hatch. Well, that plastic stropped out.

I tried the following to fix it, none of which worked:
* Wrapping various materials (electrical tape, etc.) around the "wood screw" part and threading it back into the hole.
* Packing the hole with construction adhesive and reinserting the pivot.
*Filling the hole with fiberglass, drilling a small hole in it and threading in the pivot.

Has anyone else seen this problem (and found a solution)?
Thanks in advance.

What about a blind nut insert kind like this:

I believe the blind side mushrooms out when you tighten, in your case, the ball stud. The trick is getting one with the proper threads and outside diameter.

Amazon.com has various sizes. You might even find them at Home Depot or the local hardware store.

Great idea! That's exactly the type of part I was looking to find. I might be able to cut new threads of a standard size on the Volvo part.
Thank you.

If you have a Grainger Supply near you, they list metric inserts on their website.
