How to check dampers?

It is really an easy way to check dampers (http://autotips.plentycar.com/how-to-check-dampers/). I checked all my friend’s car.

EH. Theres a little more to it than just that. Thats great for if you want to see if the things are completely dead, but theres a lot of other suspension components that cause problems that the shocks get blamed for.
