If they are leaking externally or if the vehicle is very 'bumpy'. Typically after you hit a bump in the road, a vehicle with bad shocks will continue to bounce after the initial jounce.
Sometimes it can be very hard to tell if your own personal vehicle needs struts, because you are used to how it feels. So you can go by mileage/age. A 2002 with 75,000miles, needs struts if they are original.
