Hi Walt. I was wondering that very thing this morning when I tried to replace my struts. I pushed on the struts, and also couldn't push it, but sensed that it was close. So I'm guessing it takes about 250 lbs to start to move it. I'm also guessing that the surface area of the piston is about .3 square inch, giving a pressure of about 800 psi at the extended state, probably a little more compressed. But that's just a guess times a guess. It's in the right order of magnitude, I suspect. --- In dmcnews@xxxx, "Walter Coe" <Whalt@xxxx> wrote: > I'm curious to know if anyone can say how much gas pressure is in a door > strut?
