How do you tell your Armstrongs are OK apart from a corner bump test?

In most cases they are probably ok provided they aren’t leaking or the piston rod corroded. You could have them tested on a dynamometer but a road test should be enough. The rings around the piston are normally metal like an engine and the rebound valves are spring loaded metal discs. People think they wear out but the internals that do the actual damping seem pretty robust and it’s usually loss of oil that is the problem
