Failing shock? Wasson here?

[Alan_M]

I'd just get one machined on a lathe for me if it came to that...

That video was just one arm with that little cheap tyre bar thing and i could move it up probably an inch with ease to be honest.

So take the damper off and attempt to compress it by hand and see what happens?

Basically, yes. Get the car on stands, disconnect the shock and try to lift the trailing arm/tyre up.
