Thanks for the update, Auxvache! Glad you didn't have to resort to plan 'B'.

.... and the strut stayed compressed.

Steve - insert the sound the little birdie makes, when it comes out of the clock, here! ;-)

Umm Uli, are you tripling down on your theory that gas leaked across the piston to cause the original problem even though it has been clearly demonstrated to you that such could not possibly be the case since gas springs have an intentional leak across their piston to establish the damping rate?

By far, the normal way for a gas spring to fail is simply for the nitrogen to leak out the stem seal. This apparently wasn't a normal failure since the OP says the tube is distorted. With mechanical stuff there's always an infinity of ways things can break. Yet knowing how stuff works is almost always helpful. It does allow you to scratch off dumb suggestions from people who allege credentials but don't really know what they're talking about. I hope I'm not hurting your feelings again.

Just curious, did you note whether the orientation was thin rod up or thin rod down?

Steve, in the catalogue of the same firm (Dictator) you mention, there is at least one gas spring type that works thanks to the difference between outside air pressure and inside nitrogen pressure. Granted, it is a pulling spring, while all others are the pushing kind that work as you describe it. It simply means there are different systems possible.

One of my club's trailers also had a strange gas spring failure once, luckily on an outside system: the spring gradually refused to open completely, after some time it opened only 8 inches or so. It felt as if it was blocked by some mechanical lock. But it still could be compressed for the remaining stem length, so it wasn't a blocked leak hole nor loss of nitrogen pressure. Any ideas on what went wrong?
