Hi chup and jwalker,
240 strut mount Volvo PN 1272455.
Strut can fail some ways. Usually it is the bushing materials cracking in different ways or separating from the steel parts (usually from the outside metal of the bearing assembly). The strut piston with bearing assembly can push through and bank on the hood, bending the hood.
The turbobricks article to highlight the issue of Volvo OEM early failure:

A solution is the camber plates from Kaplhenke as Offset Spherical Strut Mounts.
APA / URO strut mounts lasted from 2000 to 2012 / 2013 and replaced with Volvo OEM.
On another 240 went Meyle as an FCP Groton sales guy recommended in 2008 or so, well, I had to replace them with Volvo OEM in 2012 or 2013.
These OEM strut mounts I bought in 2012 / 2013 were the same design and manufacture as you had in the 1970s and late-late 1980s+. Open to the top ball bearing race you would stuff some grease into and reinstall that black plastic dust cap that seals out dirt and weather. (I use silicon grease (SuperLube!)
I must have gotten the last few good ones. See the dates of the article URLS, above.
After market strut mounts use a sealed bearing crimped into the center bearing shell assembly. Sealed bearings they use don't take lateral stress too well.
To find SuperLube, See:

Silicon grease does not eat the rubber bushing material.
Happy 'merikan illusion is choice primary election tuesday. Like Volvo 240 rubber strut mounts.
This is all very disappointing; the strut mounts and this sham election.
Hope that helps.
