I thought my suspension was still pretty ok when pressing down one side of the car, no real up-and-down wobbling or hissing from a leaking shock absorber. After much consideration I did replace them on the front. Man, the difference!! They were so worn you could compress the old ones easily by hand and they would stay in that compressed stage for a few sec and then they would very slowly start to expand again... Not good!! Going over speed bumps or taking roundabouts is a BIG difference now, I'm gonna replace the rear ones too 'cause can really feel a difference now between the front and the rear end when going over speed bumps...
